Which type of modification is best?
type of modification depends on how you plan to use the modified
camera. Each type has its advantages.
UV/IR filter: The
Baader UV/IR filter replacement is a much milder UV-IR-Cut filter
than the original Canon IR Cut filter and it allows the H-Alpha
wavelength to pass for deep sky. It also blocks higher infrared
wavelengths that cause poor focus and bloated stars with refractor
telescopes and camera lenses. Because the Baader replacement filter
is the same thickness as the original Canon IR cut filter, the
feature and optical viewfinder will continue to work as in the original
un-modified camera. The camera's custom white balance feature can be used
to correct color balance or an external color correcting filter can be
Modification with an Astronomik Multi-Coated Clear Glass Filter
opens up the CMOS imaging chip to all wavelengths of light, as
in commercial color CCD imaging devices. If a "Full Spectrum"
Astronomik clear glass replacement is done, a UV/IR filter will
need to be used if imaging with refractor telescopes and camera
lenses. The UV/IR filter can be either the clip-in type, 2 inch
mount or camera lens thread-on. During the camera modification,
adjustments will be made so that the camera's autofocus feature
and optical viewfinder will continue to work as in the original
un-modified camera. For details on the "Full Spectrum"

happens to the Canon Warranty?
A. Opening the
camera for the modification will void your Canon Warranty. I have
no way of being certain that the camera you send to me has been
previously altered and I will accept only unmodified cameras.
If it is clearly found during inspection of the camera you send
that the camera has been previously opened, is malfunctioning
or damaged; it will be immediately returned without modification
and the $20 shipping cost will be retained.
not accept cameras for repair service.
I receive your camera I will test its functions before beginning
any modification and also afterward. Be assured that I want your
camera to work well after the modification and I will correct
any problems that should occur as a result of the modification
for a 90 day period after you receive the modified camera. If
you send a new camera to me for modification, I provide a one
are taken during the modification process to avoid dust particles.
Very minor dust motes may occur on the modified camera and these
can be removed completely by using flat fields. These are usually
due to coating imperfections of the Baader DSLR UV/IR filter.
For normal daytime photos, if they are noticeable, they can be
completely removed using the "dust delete data" function
of the camera. The filter designated by Canon as the "Low-pass
1" filter will be left in the camera unaltered for the Baader
astro modification. It is an anti-aliasing filter that Canon is
using as a dust cleaning surface and is explained on Canon's web
site as follows:
Cleaning Sensor Unit - A key element of minimizing dust is preventing
it from clinging to the front surface of the imaging sensor. To
combat against this, the EOS Rebel (XSi) features a Canon-designed
Self Cleaning Sensor Unit. The low-pass filter at the front of
the sensor shakes off dust automatically with ultrasonic vibrations,
removing dust from the sensor assembly. The EOS Rebel XSi has
a new coating on the front surface of the low-pass filter, to
increase its resistance to dust sticking to the sensor."

How long will it take to complete the modification and return
A. As an avid
astro imager, I understand your need to have your camera returned
as soon as possible. As per the Service Procedure steps listed
above, I will not ask you to ship your camera to me for modification
or pay for the modification service until I am ready to begin
and complete its conversion in short order. The usual completion
time for the modification is within three business days from receipt
of your camera. My modification service may be closed during certain
New Moon periods.
As part of the modification I provide
and apply a free Red Shield Display. It can be used to preserve
night vision and as a protector to avoid scratches on the camera's
LCD display glass. It is a self-adhering vinyl, uses no adhesives,
leaves no residue and can be easily removed and re-applied when

feedback on my modification service and have allowed their comments
to be posted. Many thanks to all:
word sums it all up: Excellent! Excellent service, excellent turn
around time, excellent equipment, excellent help and advice. And
with all of that Im taking fantastic photographs. So maybe
two words: Excellent and Fantastic!!
entire process was very fast and very easy to deal with. Not only
did you give me advice on what to purchase but you handled everything
for me. All I had to do was wait for the finished product to arrive
and then start taking photos. Your services didnt end there
either you gave me a lot of invaluable advice on how to
use the modified camera. The Astrophotos that Im taking
now far surpass what I was taking before I bought the modified
camera and before you shared your valuable knowledge.
photos for you to see and share on your web site if youd
like. They were all taken on my back deck during November, 2009.
am very happy and very fortunate to have found your web site!
wanted to let you know how happy I am with the modification you
did to my Canon 1000D. I love it!
did a great job with a fast turnaround, and the camera's increased
red sensitivity for hydrogen-alpha emission nebulae is wonderful.
Thank you for this outstanding service that you provide to the
amateur astrophotography community.
the Light - Astrophotography by Jerry Lodriguss
did a great job modifying my Canon XSi camera. The camera functions
perfectly and has greatly enhanced my astrophotography experience.
service and communication were excellent. He provided a pre-mod
and a post mod check list showing exactly what was done and he
did all this is a very timely manner, beating his estimated completion
time. After sending the camera to Gary, it was back in my hands
within one week! You can't beat that!
website shows anyone who is interested exactly how to modify their
own camera, but with his excellent reputation, quality service,
and pricing, letting Gary make the mod takes all the risk out
of opening up the camera. Thanks for a job well done, Gary!
J Patrick Johnson PBase Celestial
Thanks for the quick turnover in modifying my Canon 1000D. I received
the camera and couldn't even tell it had been disassembled. I'm
really pulling a lot more H-alpha out of my astro-photo's. I recently
took what I consider my three best astro-photo's yet, all in one
night, and cannot wait to get back out.
have also been pleasantly surprised with the quality of my daytime
images using only a quick custom white balance. Overall, I couldn't
be happier with the way the transaction went, and I'd recommend
your mod service to anyone considering it.

the Lackawanna Astronomical Society Web Site
modified my Canon 450D (EOS XSi) this past year. His work was
excellent, and turnaround was fast. He is very thorough in his
work. He takes the time to make test images both before and after
modifications to insure that autofocus, dust spots and exposure
control are unaffected by his work. In my case, Gary had the camera
fully modified in under three days, then delivered the modified
camera to me in person at a local star party. He spent a few hours
with me for first light exposures, teaching me technique and the
intricacies of effective astrophotography. I look forward to many
more years of Garys advice and guidance as I learn this
exciting new hobby. I would definitely recommend Garys work
to anyone not wishing to tackle a camera modification by themselves.

is my testimonial to your service. You have my permission to publish
it wherever you see fit.
Honis' camera modification service is a class act from start to
finish. His attention to detail is second to none. Upon receiving
my camera, he immediately ran it through an intense battery of
tests in order to ensure proper operation prior to modification.
There was never a doubt in my mind as to his progress during the
entire process. His communication to me was outstanding. Upon
completing the process, Gary ran it through the entire test battery
again to make sure everything was operating as intended.
Including shipping time, I was in receipt of a fully functioning
astro modified DSLR in 5 days. It has functioned wonderfully since
its arrival and I look forward to putting it through its paces
every new moon.
if this wasn't enough, what is most impressive to me is Gary's
continued commitment to his work and love of his hobby. Under
no obligation, he has offered a wealth of advice to me weeks and
months after he completed my camera's modification. I have never
met Gary personally, but I am under the impression he does this
because he loves it. His answers to my questions were personal,
meaningful and and well researched. He has taken some of the most
beautiful pictures I have ever seen and I believe his dedication
to mentoring and teaching our small community runs deep. I can
say, with the highest of confidence, that you will be happy with
any service that Gary offers.
another note, a
picture of M33 I just finished. Thanks for the advice on photoshop,
I'm slowly, but sure getting better at this...
Ken Pendlebury's Photostream
am absolutely delighted and impressed with the Canon 450D DSLR
modification you performed for me two weeks ago. As a physicist,
I probably could have done the modification myself, and considered
it much earlier after seeing your modification instructions on
the Internet, but I was reluctant to undertake the task for various
reasons, not the least of which was the fact that my current general-use
Canon DSLR 10D had been purchased for my wife, who had serious
reservations every time she saw me mount it piggyback on my telescope.
Modification of that camera by me would have resulted in divorce
or worse, after 54 years. A different Canon DSLR camera body was
mandatory, I decided.
was very happy to learn that you performed the modifications as
a service, and contacted you immediately. You informed me as to
your currently available modified cameras, and told me exactly
how and where I could buy other refurbished Canon camera bodies,
which could be shipped directly to you from the supplier for your
made the whole process very easy, and as an astrophotographer
yourself, even suggested you could get the modified camera to
me by New Moon, which hadn't even occurred to me up to that point.
The fact that you completely check-out the camera and its performance
both before and after the modification gave me a lot of confidence
in the camera and process.
kept me well-informed via Email of the status of the process,
and made a lot of very helpful suggestions regarding the camera
settings and shortcuts in astrophotography, such as how to focus
on the stars using Canon's LiveView feature, something I had not
to your suggested timeline, the modified camera arrived on New
Moon, and I took pictures of the Horsehead Nebula that very night,
and the next few nights. Your earlier suggestions and insights
allowed me to take pictures immediately, without a drawn-out learning
It performed spectacularly on the hydrogen-alpha emission, something
my unmodified Canon 10D was absolutely unable to do, no matter
how long the exposures.
had since 2002, an SBIG ST-7 cooled CCD monochrome camera with
a color filter wheel which I rarely use due to the fuss of taking
all the exposures through the color filters, along with necessary
flat fields, etc. Multiple short exposures with subsequent "stacking,"
make the TEC cooling far less important. With the purchase of
my earlier Canon 10D DSLR, I stopped using the SBIG ST-7, except
for the hydrogen-alpha emission pictures such as the Horsehead
Nebula. Now, with the modified Canon 450D DSLR, I'll probably
never use the cooled ST-7 again.
in all, Gary, your modification service has been a very pleasant
experience, and I'd do it again "in a heartbeat," and
wouldn't hesitate to recommend it to others.
Arthur R. Kotz (Art)
a great service you offer!
ordered a refurbished Canon 450 from Adorama and had it sent directly
to Gary for The Baader filter modification. The Canon 450 arrived
at Gary's with an obvious scratch on the LCD. Gary immediately
contacted Adorama and had a new refurbished Canon 450 sent to
him and he returned the scratched camera to Adorama. After a couple
of days and a thorough inspection I received my modified Canon.
I could not be happier with the results of this modified DSLR
camera. The deep reds from nebula show up on even the shortest
exposures. Thank you for the quality service you offer.
Scott Kindt's DSLR Gallery
had a much longer wait for my Canon DSLR modification than most
people due to a temporary worldwide shortage of the replacement
Baader UV/IR filters. Because of that, I'm probably even more
appreciative of Gary Honis's incredible customer service ethic
online camera modification video is what sold me on his services
in the beginning. Anyone who would provide that free detailed
instruction, inspite of the fact that it's his business, was a
special person. I was aware of the possibility of a replacement
filter shortage in February, when I ordered the modification of
my 4-month old Canon XSi. During the 3-month wait for the filters,
Gary not only kept me apprised of progress on a regular basis,
but offered me the alternative of a clear filter replacement,
providing me with detailed information that was extremely helpful
in deciding that that was not for me. I continued to receive updates
from Gary every 1-3 weeks, until finally in early May, he said
it was time to ship the camera to him.
When the camera was in his hands, he provided a complete report
of its function in a pre-modification checklist. It was only days
before I received the modified camera back with a post-modification
report and instructions on resetting the white balance, which
he had already done for me. The camera looked like new and operated
At that point, my patience was tried by the weather, due to one
of the wettest and cloudiest springs I can remember in Colorado.
Two weeks after I received the modified camera, I was finally
able to use it at my club's dark site. Despite the haze and poor
seeing, the camera produced some wonderful images, including one
of M27 that met all of my expectations: improved sensitivity and
absolutely wonderful reds.
I would heartily recommend anyone to purchase camera modification
services from Gary Honis.
Thank you, Gary.

You modded my Canon XSi a few months back. I have finally been
able to use this and I just wanted to say Thank You for a job
well done. Your service was excellent and very professional (availability
to answer questions, quick response times, packaging, etc). There
was no doubt that my camera was taken care of while in your hands.
I have taken several images of red emission nebula and the results
are outstanding. Thanks again.
I just wanted to let you know how much I have appreciated you,
your modification service, and your extreme professionalism through
this entire process. Though taking photos is not new to me, the
world of astrophotography is, as is using the camera I purchased
(Canon XSi 450D). You have guided my steps along the way, and
your help has not just been of value, but your dedication to professionalism
in your work has helped me to know there are others out there
who really CARE about the product and services they provide to
others, and even continued follow-up services, guidance and assistance!
Thank you for starting me on a new journey. I look forward to
the new world you have helped open for me.
was received here in very rural Nova Scotia on Thursday morning,
July 28. That's six days in transit. Pretty good. All seems well.
In fact I am very pleased with it and have been burning up the
nights as there has been an unprecedented run of good nights since
I received it and at new moon too. Quite a bonus!

in mind, I am not an experienced astrophotographer. I am very
happy with these first results. Thanks again for the impeccable
work . . . I could not tell the box had even been opened!

wanted to let you know everything arrived in good shape. Your
color balance setting you performed on the camera looks good to
me. Appreciate the display red covering. Ill let you know
when I get back out and take a few shots with the modified camera.
Waiting for Celestron to return my CPC, at present. Im very
pleased with your courteous, quick and professional modification
of the camera. I will highly recommend your services to others
in the future.
doing some research on the web, I chose Gary to replace the infrared
blocking filter with a Baader UV/IR filter. I ordered a Canon
EOS 550D in January 2011 and had it shipped directly from Adorama
to Gary Honis. The email messages from Gary were very informative
and he made every effort to get my camera modified and delivered
quickly. His DSLR Modification Service comes with my highest recommendation.
By February 2011, I had my newly modified Canon EOS 550D and immediately
set about testing it with some of my favorite Nikkor lenses (105mm
f/2.5, 180mm f/2.8 and 300mm f/2.8). The images are remarkable,
especially when I use the Canon Live View feature to carefully
focus on a star field. I'm so pleased with the Canon EOS 550D
that I selected it for a project to image all 110 deep sky objects
from the Messier Catalog using the Takahashi Epsilon 180 Hyperbolic
Astrograph. Visit my Messier
Catalog Photo Gallery to see the image quality delivered by
this camera and telescope combination.
Fred Espenak's Astropixels.com
for the quick work, Gary. I really appreciate the nearly daily
updates also its really nice to know exactly what
was going on with things on your end as the work progressed. With
so many other companies my gear stuff just disappears for weeks,
if not months, at a time and even direct requests for status go
unanswered (thanks, Celestron). I really appreciate the service
- too bad I only have one camera to modify or Id send another
have gotten my UPS status email on my end and it looks like it
will arrive ahead of time they are saying tomorrow (Wednesday)
already! Thanks again I cant wait to get the modded
camera out under the stars and see what a difference it will make
to my DSLR astrophotography.
