Dolphin Head Nebula
Had a go at the Dolphin Head Nebula a few nights back
sh2-308
Skywatcher Esprit 150
iOptron CEM120
asi2600mc no filters
88 x 180 second exposures for a total of close to 4.4 hours imaging time.
Flats, darks, bias
Processed and stacked all in PixInsight.
Had a bit of an issue with a bad halo on the bright star, after a few hours playing around trying to figure things out with PixInsight and the pixel math, I have got this image,
I am sure it can be improved on, just still working my way through PixInsight.
Next time i think i would reduce the exposure times a bit to see if that improves halo issues.
Looks very grainy on here, but don't have an Astrobin account to show a larger full version.
