Hi -
That's the excellent image, I love the colours.
Attached is one I took 2 years ago, just using Ha and OIII. The scope is 30'' F3.5 Dobsonian on unguided Equatorial Platform.
Each exposure was only 15 seconds and there were 30 Ha and 30 OIII frames so total of 15 minutes data.
Camera is Atik Horizon mono and all processing done in Pixinsight.
I need to try the hubble pallet
Regards
David
