#c63 — Public Fediverse posts

Here we go. My most ambitious processing to date.

The #HelixNebula (aka #C63 , aka #NGC7293 ) is probably the closest planetary nebula to Earth.

This image is created from subframes taken with my #Dwarf3 over 2 years and 18 sessions. I started with 4791 frames, 3816 ended up being stacked. A total of over 55 hours of observing time. Most of which I slept through. It took nearly 10 hours to stack inside the telescope itself.

In amongst the Ha/OIII frames there is also one 3 hour session of SII/OIII, which brings the blue out a bit more.

Restacked using the Dwarflab onboard Megastack, then post processed in their cloud Stellar Studio. Final recombining and tuning in #Snapseed .

The #astronomy group I associate with, #AGWA have a target of the month each month. This month it is #C63 , the #HelixNebula .

Now over the past few years I have shot this target a lot.

So I am now gathering together *all* my session data, going the Full Tim and stacking it all. I don't know how many hours it is. Lots.

Wish me luck!
