First attempt at M31

Recommended Posts

Hello all :)

The last couple of glorious nights have let me try M31. This was almost 2 hours of 2 minute subs unguided, with some darks and flats. Not sure about whether I am processing adequately, and I think I need to switch to RAW as the jpg format seems to leave me with some artefacts in DSS.

Anyway, I'd appreciate any comments on how to improve it. I intend to try and gather some more data over the next couple of nights.

I think you are processing just about adequately!! Exellent image. Certainly use RAW if you can - I always set the camera to RAW+JPEG so I can have a quick look at the subs as they come in - useful if there are any problems!

Golden rule - always use raw as jpg compresses and you loose all your hard photon gathering time and there is no way to undo the compression.

I think this is a great effort - well done. I like how vibrant and sharp it seems on first viewing, catch's the eye :-)

Thanks for the comments guys. 2 minute subs are pushing it a bit on my mount and tripod but I managed to get another hour of them last night and will try for some more tonight if the clouds stay away.

The scope is my SW ED80 with a SW 0.85 reducer. The reducer is essential really, otherwise M31 refuses to fit on the sensor of my canon.

Nice image. Definitely worth shooting in RAW though... and on cooler nights in the winter you'll get a much better signal to noise ratio as well.

Good work.

What were the camera settings by the way iso speed aperture. I took 95shots at an iso of 800 and 40 seconds and still not getting the outer lanes coming through :-(
