I did this one a couple of years ago at 50 minutes and got more dust lanes for some reason my photoshop skills need a good sorting out but anyway my first attempt (this year) 3 hours of data. Really expected more but ill capture more data later and just keep trying to improve on the photoshop side

1200 @ 45 sec subs

Hi Scott,
Your stars are looking slightly oval as though guiding is not quite accurate. That won't be helping your resolution on the target either. Three hours should be starting to see some definition in the structure.

Alan was referring to the lenght of each sub. Aim for 3 mins at 1600 ISO for each sub and see how you go. Aim for middle third of the histogram depending on light pollution and heat noise.
Cheers,
Bo

Thanks. I didnt go throughall the subs magnified so im sure i have to eliminate some that where the guiding moved a bit. When i was capturing i had it magnified and could see every now and then some subs had moved a bit through bavckyard eos. The histogram was far left and nothing really to play with when i did a little longer it went more grey so i was a bit worried about that. ill try longer exposures and combine with the good subs i already have. was a bit windy last couple of nights aswell

very nice, love this galaxy! can't help thinking the problem is lack of tools in photoshop. I reckon wavelets processing will bring out the detail with ease. But dont think ps has anything like that. if you are patient and willing to try there are tools for photoshop to deblur (de-motion blur) images which is what your subs have so you should be able to process yours subs so the stars become round, that should pull the galaxy signal into focus again slightly. then register and integrate again and detail should sharpen up for you. i've done the same in the past even though it was time consuming but it works. save you scraping the subs.
