Here are September's entries!
NGC 7129 Nebula and NGC 7142 cluster
Imaging: SW MN190, Modified 550D, EM-200, APT (Astro Photography Tool), PHD
Guiding: Meade 90mm, DSI 1 Pro
Subs: 8x600s = 1h 20min, ISO 1600, no calibration - only dithering
Processing: DSS, PS CS3
Location: 2012/8/17, Nedelkovo (890m ASL), Bulgaria
NGC 7129 in Cepheus
24 exposures 5 min @ 1600 + 12 exposures 1 min @ 1600 for star color
Imaging scope = C8xlt on the CGEM mount
Imaging cam = Canon 450D xsi
Guide scope = Orion ED 80
Guide cam = Meade DSI osc
Aquisition = Backyard EOS
Guided with PHD
Stacked in DSS
Processing = PS CS5, Noels tools, Star spikes pro
Here's my NGC 7129:
High Resolution Image and more image info available at
This is a stack of 171 x 3 minutes subs (8 1/2 hours total) using focus stacking with a Celestron C-8, Celestron focal reducer at f/5.8 (1160mm), and a Gary Honis modified Canon 450D (Baader mod). Guiding is with ONAG on-axis guider, Lodestar autoguider, and Phd guiding.
For my version of this target I went a little different and decided to shoot a widefield of the area to see if there was any dust nearby.
It turned out the ED80 gave too wide a field for this so I croped it by 50% and lost some resolution as a result.
26 10min subs with no filter at ISO 800 stacked in DSS then adjusted in PS CS2. Canon 500D(modded) , Orion Atlas mount and the scope was an ED80 with WOVII FR and a 7x40mm finder as a guide scope.
Congratulations and good luck to each entrant!

I'm quite honored to have my image selected, as I was extremely impressed with the very high quality of all 3 of the other entries. I think the voting clearly reflected this - all of our images received a respectable split of the vote. As it happens, I didn't vote at all - but I easily could have voted for any one of the other images. So, congrats to Ivo, Scully, and Erik for their excellent images!
I'd like November's target to be NGC 772 - a very cool Arp galaxy with lots faint, fuzzy friends.

Thank you for the congrats. As far as entering the contest, rules, etc - Each month when Charlie posts the Challenge Submission thread, he includes the rules at the top of the posting. So, to find out about it, you can look at the October 2012 DSLR Challenge submission thread. To enter your submission, just reply to Charlie's posting and include your image, links to hi res version (optional) and image info.
As far as choosing the targets - whoever wins the contest for a month chooses the target for the following month. So, Bruno won the August Challenge (voting done in September), and he chose October's target as NGC 7293 (Helix nebula). Similarly, I won the September challenge (voting in October), and I've chosen NGC 772 as the target.
For clarity - NGC 772 IS the target for November's challenge - have fun with it!

I did vote for your's but all the 4 images were high quality so it was a difficult choice.

Thanks Al - I agree with you 100%.
