Hyperstar Horsehead

[AKB]

Cracking night, last night (15-Dec-2017) although with temperatures a bit below freezing and gusty winds.  Having discovered that the spacing for my QHY8L on the Hyperstar was incorrect by 3mm despite using the Starizona-supplied spacer, I'm now using the excellent Baader Universal Filter Cell to give me nearer to the correct spacing.  Still not quite there yet, though.

To check it all out I went for a number of targets for a relatively short time.  Here's my go at the Horsehead.

• Hyperstar 9.25" with Baader UFC and IDAS P2 filter
• Avalon M-Uno guided and dithered with Nebulosity
• 20 x 60 seconds
• Processed in PI  (shhh... I'm still learning)

Haven't really got the hang of noise reduction, (and seems my bias or darks aren't handling a bad column) but really the answer is more data, and I suppose this isn't too bad for  just 20 minutes...

Advice more than welcome.

Excellent result looks natural trying to tame Alnitak is abit of a [removed word] though.

Thanks for that.  I haven’t done anything special to reduce Alnitak, except trying to be a bit careful with the stretch.  You can, at least, see that it is a double, which is the litmus test for me.  It should be improved by tidying the camera cables across the corrector plate and also getting the spacing and tilt exactly right.

Really is a great image for 20 mins. That is equivalent to one of my Ha subs
