A Horse in Ha

A few clear hours last night so with the moon around picked the Horsehead Nebula (IC 434) / Flame Nebula (NGC 2024) and surrounds for some H-alpha imaging.

Maybe one day I'll get the right weather to get the RGB data to go with it, but the way it's been I will probably have time to save up for my other NB filters before then...

Cheers,
Mark

Very sharp! I like it a lot, and can't wait to see what adding the RGB data will do.

Nice Mark, great start.

Thanks guys - my only problem is that I'm enjoying the Ha results so getting around to the RGB with limited sky time is...hard. :D

Fantastic detail in that Ha data! It’s really hard to keep momentum on a project when you can’t get consecutive clear nights but hope you can finish it this season! Looking forward to seeing the final result

I think I prefer this PoV.
