NGC281 - Pacman Nebula in Narrowband

Well I have to say this is my looooooooongest project to date, a total of 23.75 hours just for the hubble palette composition, so here it is

39x900S in 7nm HA (9.75 Hours)
30x900s in 7nm OIII (7.5 Hours)
26x900S in 7nm SII (6.5 Hours)
Each filter has 25 darks and 25 flat frames

Total exposure time 23.75 Hours

WOW Simon - looks great. I learned quite quickly when I started this hobby that long total exposure time was the only way to really bring out fine detail and go deep. Your patience in getting over 23 hours has been well rewarded.

Thanks Brendan, I think I'll be stretching to 20 or 30 min subs for Narrowband in future, the mount is rock solid and has been thoroughly tested, an RMS of around 0.37

Hello,

This thread begun 2.5 yrs ago so hopefully there's still interest in it.

Not a great sky last pm with a very bright moon but I've begun a Pacman project hopefully I can add more data to over the next while. I got 10 of 10s same of 60s and 5 of 30m Ha subs so far the last infected by encroaching cloud. Subs are ok apart from some barrelling towards perimeters any got heads up on explanation of that or rectification?

I intend to apply some new processing techniques I've been acquiring lately from Josh Smith

But appreciate any tips on approaching your fine Pacman image there.

Here's some initial processing of stacked 5 of 30min Ha

Hey there

Well I must admit, the way I used to process in PhotoShop is not how I process now, I use PixInsight for all of my processing now, and the past few days, I have also been adopting the Stacking and Aligning with PixInsight too, so I have almost surely Ditched Maxim-DL, Nebulosity and Photoshop for my Astronomy image processing, here's a link to another Pacman Nebula of mine processed with PixInsight
