NGC 2903 Getting there.

[DaveS]

I collected more data, though some was degraded by cloud. So 15 subs Red and Green, 13 subs Blue after stacking in DSS. Got rid of the asteroid images. Bashed in AstroArt 8, but there are still some annoying alignment issues which I'm struggling to fix.

 

I'll park this for now, but may try to get some H-alpha when we next have a clear night with little moon. Perhaps next year.

Despite your perceived problems it's still a quality image...plenty of detail and colour coming through.

Hi Dave,

You have some good data there. The galaxy looks great but your stars seem to have lost colour. I don't know your workflow but perhaps treat them separately from the galaxy with a more gentle stretch and recombine them when stars and galaxy are how you want them. That may get your colour back and the slight differences between filters will likely become invisible.

Thanks both.

 

I haven't done starless images yet, for a variety of reasons but perhaps it's time to see what's available to work work AstroArt. I think Starnet++ is available as a plug-in.

 

Not sure how well it will work with diffraction spikes.

Most of my images have diffraction spikes left behind after doing a star extraction. Generally its not a problem I just process them along with the nebula/galaxy. The spikes are low intensity compared to the star body.  Starnet++ also has standalone app version I believe Download | StarNet (starnetastro.com). I haven't tried the V2 version myself yet.

Thanks, will have to give it a try.
