This is my shot of the Andromeda Galaxy taken whilst on holiday in Scotland two years ago.
It's 36 frames of 3 minutes each at 1600 iso with a 300mm F4L lens on a modded Canon 600D

all mounted on my Astrotrac, no filters used as it was a very dark site, it was stacked in DSS

as a 32 bit tiff followed by lots of Photoshop.

Never thought I would get such a good response to this thread.

Keep them coming, it is becoming a good showcase of different style and talent!

I really appreciate all contribution, feel free to update if you add more data / reprocesses and get it better.

Anyway I promised I would embarrass myself, so here goes my first ever astro image and M31 to boot!

Come to think of it, I now wonder if that is even pointed at the right place! 

Not the right shape at all hmmm.

Some cracking M31's  here, I had to dig deep in the imaging pit to find one I posted here quite a while back

Its a shame i dont have  some of my vey firts attemps to hand as these posted on here would make mine look even worse :grin:

any way here was my take on it.

10 x 2 minute subs iso 3200 in monochrome
10 x 4 minute subs iso 800 in colour
10 x 2 minute subs iso 400 in colour
10 x 2 minute subs iso 200 in colour
The usual set up Quattro 8 inch cf modified Canon 1100d with cls clip filter,
neq6 pro mount , Mppc coma corrector,qhy5 auto guider with Phd

processed in PI and PE

This was my best effort on M31 after many attempts over the years, not an easy one but well worth the effort. Apart from getting good enough subs and enough of data the hardest part is the processing and drawing out the detail from the outer lanes.

This is my effort - unmodded Canon 1100D, ED80, Orion Sirius, unguided, 7 x 300 subs, no darks, bias or flats.

Stacked in DSS and tweaked in Photoshop.

To throw in a Pentax DSLR in here :

M31 take 3

This is pretty much first few attempts at astrophotography. Limited to 30 sec subs.

Bump!

Anybody else out their been imaging M31?

Seen some fascinating images on here, many different people attempts and processing styles.

I was thinking, imagine if you took all the best images on here and stacked all the raw data together.

Now that would make one awesome picture!

Well done on this image, was featured on sky at night a UK astronomy program.

Thank you Chris. That was quite a thrill to see my image come up on screen! Two other images in that sequence were by SGLers too - StuartJPP and Rob Preston - the next two images in the piece. Not sure who the final image was by though - a Trevor somebody!?

That will be Terry Hancock...he's got some excellent images.

Apologies Terry! Quite where Trevor came from....?! Is Terry an SGL person?

I've just done my research and yes indeed, Terry is the creator of fantastic images. As the S@N sequence suggested, this is what we are aiming for!

My 2014 M31 project is set to commence this evening, clouds willing.

Nice one Gav, personally I think that Thomas has set a high bar! (although with a DSLR) 

Would be interesting to see where you land with a CCD and with integration time.

(F-Ratio and Dark sky aside as Thomas has some pretty impressive kit in a pretty dark location)

      M33 captured over 4 nights, 16hrs of data using 300sec subs, darks from library, mixed flats for an average and bias frames. Camera: Canon 600D. Everything put into Deep Sky Stacker and the resulting image processed in PS.
      I used a video made by Scott Rosen on processing to help me process and I learnt some really powerful techniques to use in PS.  I think this is my best processed image to date, so I feel happy I have made some progress. Looking forward to reprocessing my old data armed with the new knowledge 🙂.

      So, although I had some issues with my auto guiding (which I found out afterwards) I did manage to get 9x180s exposures and 5 darks of Andromeda and give both stacking (using DSS) and processing (using GIMP).
      My first attempted DSO....
       
      I am pretty sure that people could get far more information out of the TIFF file from the stack.
      Hopefully I will get another clear night soon. I am in a heavily light polluted area so I do have a clip in filter on my DSLR which I think took a lot away.
      More practise needed!

      Hi All,
      Having had to move to an apartment where I could not use my CPC 1100, I decided that I have to see what I could do with my NexStar SLT 102 (alt-az achromatic 102mm f6.47 refractor). Setting up on my narrow balcony was challenging and the altitude bearing was so loose that it almost moved from the weight of the Canon 700D. I could not see M31 in the estimated 3.5 magnitude sky so I did a two star alignment and used the live-view to focus on a bright star. I then took a 15 second exposure after slewing to M31 which allowed me to see that I had it in the field of view. After a few more 15 second exposures and playing with the motion controls I managed to get it centered. The resulting picture is from 39 subs of 30 seconds at ISO 1600, 9 flats. The images were stacked and stretched with Siril and then I played with the curves on Gimp, cropped and scaled. Not too unhappy.
