Raw imaging advice

[Pete D]

Decided to image M31 last night with my 200p on a NEQ6 with a Nikon D3100. After advice shot in Raw with 30x30 secs exposures. The images looked ok on the LCD but when put on dss the images were very dark and small and it could not idendfy any stars even on 2%. Any help would be appreciated. When I did a few in JPEG it didn`t have any problem picking out the stars.

What are you using to process the image after DSS? I usually stack in Nebulosity and then stretch the image in Photoshop; your image looks a lot like a pre-stretched one!

DSS also has a hard time dealing with star trails, dont know why jpegs would work over raw.

Have you tried stretching the on screen image by pulling the white point slider to the left - see top right hand corner of image

[Pete D]

That is the image before putting it on DSS. Tried moving the slider put it doesn`t help.

Strange, I copied your image into DSS and moved the white point to the left and I can get the image to brighten to full white. Maybe I am not understanding your problem completely?

It will not pick out the stars to stack the images together
