This one is half a dozen 5min subs at iso400 with M83 approaching zenith from the east. My longer exposures after these didn't show the object due to pollution to the west of me. I gotta move

I added an image of what it is supposed to look like of course it's clipped for the purists but wooohooo...
Hi Tandum

Images such as the one you have posted as an example usually take several hours or more with dedicated CCD astro cameras mounted on high quality scopes and mounts etc. Here is a link to an IIS members image of M83 that took 6.1 hours to collect. Jase is one of the guys to emulate on this site .....

I think you could probably get a better image with your data by using GradienXTerminator, I find it very useful. As Jase would say taking the image is only part of the game, the processing is the rest.
I have a long way to go yet to get anywhere near his and a few other members standard. Keep at it !
I've done a quick adjustment of your image with GXT and PShop .... hope you don't mind.



p.s. I've gotta move as well .... hate the city lights !
