Hi,
In addition to io, we now have a Facebook QCUIAG group.
It is a closed group and so far a number of QCUIAG members have joined.
If you are on Facebook, please join QCUIAG there.
If you are not on Facebook, or don't use it often, QCUIAG is a good reason to join and it could be the only part of Facebook that you use.
Discussions and images have already begun to be posted.
If you have a website or astronomy blog of your own, then please post that on the? Facebook QCUIAG group.

Hi Sylvain, and all,
Rare poster, long-time lurker. Modified a Toucam, back in t he days. I work mostly with a Canon Powershot SX50 with the CHDK modifications, these days, which, I think, not only qualifies, but deserves more attention within this group.
????????????????????????????????????????????????????? -P-

Thanks I have found the group

Hi Peter,
I'm glad to see that you are still looking at modifications of
cameras─good QCUIAG tradition.? I can look up the SX50 but what
is the CHDK modification?
I too modified the old Toucam, one bit the dust when the USB
chip failed, but the other one, with modification and cooling
still works although I seldom use it these days as KCCDTools
doesn't work on my modern computers although the old Philips
software does.? One strange thing I discovered is that the trick
of raising the colour saturation to 100% to show up differences
in lava composition doesn't work with my Imaging Source DFK
camera nor (I think) my DSLR. I don't understand that─presumably
something to do with the colour filters on the chip.
BTW there have been at least 21 others who have joined QCUIAG
here since we did.? I don't do a lot of QCUIAG-type work these
days but do experiment a bit with different optics.? I wonder
what the others are doing.
Best wishes,
Peter

Hi, I am currently testing two cheap CMOS webcams for mainly lunar imaging, and working with my partner Nicola (she is a brilliant programmer) on AstroDMx Capture for Linux. More details and discussion on the QCUIAG Facebook group. Please consider joining, it is a great place to discuss things and post results.

Hi Peter,
??? The CHDK mod. is actually a "firmware" mod. to the Powershot
line of Canon cameras. In effect, what it does is allow one to
access and control many aspects of this line of cameras to a much
larger extent than the manufacturer "built in". For instance, the
basic longest exposure is 15 seconds, but, via the CHDK system, I
can expose for anywhere from seconds to hours, giving me access to
phenomenal deep-sky objects, with everything from wide-field to
1200mm telephoto, all through a single, dedicated lens system.
??? Take a look at the system via Wiki, and here's a sample photo I
took a while back of an Iridium flare, using the long exposure
feature and a fairly wide-angle lens setting...
??? Do I have your attention now?
??? ??? ??? ??? ??? ??? ??? ??? ??? ??? -P-

It is obvious you are not interested in CHDK users.
I was on the Yahoo Group for 6 years. I am deleting myself from this group.

I have CHDK installed on two Canon cameras I use for normal photography.

Re: Canon Camera Modifications - CHDK Resources
Wow, Jonas!
??? Thanks you for posting this wealth of information. I'm an avid
CHDK user, but it has been a few years since I checked in on things
there.
??? I will vouch for the fact that it is a great leap forward in
Unconventional Imaging, for those that are willing to invest in? the
line of cameras that are supported. To be able to take pretty darn
good, single-frame deep exposures in color, with good hAlpha
sensitivity, and, if willing to spend the time to stack and process
a collection of images, or to take time-lapse, or even
motion-detecting photos through a lens system that can go from
wide-field to telescopic is truly new ground.

Hi Jonas,
??? I see you've listed AstroKam. Are you using it, or just
mentioning it? I've been trying, sporadically, to get it to link up
with my SX50s, with difficulty. But I'm an avid user of CHDK,
primarily in astrophotography, and love it. I use the cameras in
regular mode for all of my birding.

Focal reducer with SW 150mm F5
Hi everyone
I thought to get a slightly bigger FoV with the Skywatcher Startravel
150mm/F5 scope. It is already a fast scope, and initial experiments with my
collection of a 31mm reducers were not promising: stars turned into seagulls
and worse.
I took a punt on the 2inch Orion 0.8x Imaging Focal Reducer - it works quite
well. Here is a shot of two galaxies NGC147+NGC185 (Green filter, 4x120s,
minimal processing). Not a great pic, but a great density of stars - and
they are pretty well behaved over the entire frame.
Here is an RGB of M31, which shows a usefully bigger FoV compared with my
previous efforts. M32 and M110 are both in the frame. I have tried to bring
out the inner gas clouds circling the core which are usually burnt out.
SW 150mm F5, 0.8x Orion Imaging Reducer, Atik 460EX mono. Darked and
flatted in Dawn, stacked and initial stretch/gamma in Registax5, processed
PSE10
B filter - 43x60s
G filter - 37x90s
R filter - 102x35s
Total 9480s
Here is a brighter version:
I took a few sighting shots of a couple of other targets, looking forward to
the winter season:
Here is M45, G filter - 13x300s, total 390s. I have been trying to catch
the dust clouds in M45 for years with my old 8bit imager, and never managed
it. Here they pop out in the 16bit Atik - just shows how important ADC bit
depth is:
And M42, G filter - 13x120s, total 1560s. The dynamic range of the camera
is impressive - on the unstretched raws the trapezium is not burnt out and
clearly resolved.

These little Powershot cameras are absolutely amazing. LiveView on PC and remote PC control including lens zoom. I have 2 cameras I got secondhand. I use my SX230HS with the CHDK intervalometer for all night meteor watch. My SH530HS with its amazing 50x zoom lens is able to just about match my 1100D/Nexstar 4SE combo.

Displaying images of equipment and results
Hi,
I would like to encourage everyone to join the QCUIAG Facebook group even if you use Facebook for no other purpose.?
There you will be able to display directly, your results, and be able to engage with other members in discussion about yours and their work.
Clear skies
Steve
PS Many people have a negative reaction to Facebook in general, myself included. However, it does provide a suitable and easy forum for the display and discussion of QCUIAG's work. Moreover, there is absolutely no need to engage in any other Facebook activities, so why not?

Re: Displaying images of equipment and results
Hi Steve,
??? I'm sure I'm missing out by not, but I just don't have the time.
I get what I can from here, first thing in the morning, and then I'm
out. Maybe in a year or two, when my life calms down some, that
could change, but meanwhile, I'd like to encourage people to
continue to use this format for sharing, too.
