Hi Everyone. This is my first image with my newly self modded 1100D, I think I like the potential the modd as given this camera. These subs are from last night 24.10.23. I think I might have pushed the data a bit to far, but I have another hour and a quarter of subs from tonight to add to it. I'll fix it all up once I add the new data. As always, critique and advise are welcomed. I want to improve. Thanks for looking.
Image details:
Object: M33 Triangulum galaxy
Location: North of Townsville NQLD
Camera: Modded Canon 1100D Astronomic CLS-CCD clip filter
Scope: Newly acquired carbon fibre Skywatcher 8" f/4 astrograph, MPCC
Exposure: 20 x 300sec @ ISO1600
Guiding: QHY5 4" f/5 newt and PHD
Captured with: APT - Astro Photography Tool
Stacked in DSS and processed in Photoshop CS2
I created an astrobin account this morning and uploaded a better quality image, still not full size but much better. http://astrob.in/61511/
Well, I finally got around to adding the new data, re-stacking and reprocessing. I had to crop it slightly to remove stacking artifacts. I gotta tell you that I am not sure it was worth the drama, as this time around I really struggled to rein in the reds. I am not sure whether I like the second one or the first. I must be doing something wrong somewhere in the processing because every other pic I have seen of this galaxy has much more blue than red. Please be honest and tell me which you like better and why, (I want to learn). If you have suggestions as to how to make it better I am all ears. Thanks for looking.

Reason: Added more data
Rex, that shot comes up quite large in my browser, might be better to reduce the size and then save as a jpeg, you should get a better quality image to look at then given the file size limitation of the board.
Thanks Laurie, since I got this scope I have been really enjoying my astrophotography. I don't feel like I slog my guts out and get nothing in return.

Thanks Rick, it ranged from 17deg when I started to 39deg at transit. Not long after transit my northern sky is blocked by a tree. I got 23 subs in but lost three due to guiding errors. Can't have everything I guess.
That's the advantage of living here in the north. We get to image objects most of the rest of Oz can't even dream of doing When it's not raining, or all smoked out, or hazy and humid
That's a really decent M33 Rex. Its a tough one to do justice to and I like the Ha regions you've managed to bring out.
Thanks very much Rob. Hopefully I can do as well when I include the next set of Data.

Thanks Pete. I love the northern sky from here. Quite a few objects that I hope to image over time, M31, Veil, North American Neb, Pelican Neb, Crescent Neb, just to name a few.

Nice piccie
Thanks Carl. Yes the dreaded wet is definitely on the way. the humidity is rising day by day. Won't be long and it will all be over until next year

What was it like to mod the 1100D? I'm toying with the idea but am worried about "all thumbs" syndrome with itty bitty screws and cables.
Thanks Kevin, I feel I am improving. Modding the 1100D is actually not as hard as most people think. Most of the later models have two flters, one you remove and the other you keep. To be honest the only really stressful bit is prying the glass out. Unfortunately the filter you remove is under the one you keep, so have to be very careful not to break the first filter when your removing it to gain access to the second. Other than that, you just take your time and don't rush it.
I've really enjoyed the way you've sunk your teeth back into astrophotos. you are getting great results. you could perhaps turn the red down with PS, by using selective colour? Did you realign the RGB channels after stacking as i believe this gives a stronger red signal on a modded DSLR.
All the best, and keep posting your shots - been terrible weather in melbs so living vicariously through others shots!
