After whinging about no clear skies for 2 months, last night co-operated JUST long wnough to satisfy me, and managed just on 2 hrs of TOTAL data (7 min subs in Lum-Ha-OIII and SII) - thankfully I got more Ha than anything.

OIII subs a bit wonky, so will need to work on it.

This is a straight colour combine straight out of CCD Stack (I experimented with blends to see if I could come CLOSE to real colurs... FAIL :) ) and then thrown into photoshop with a slight Imagenomic noise reduction - it's still noisy thanks to the paltry data even denoised :)

Yes, it's gad awful, but I got out and got me some photons! Tracking was beautiful all 2 hours (not a beep), everything came back like riding a horse.

Hereby, I present the worst NGC2467 known to humanity :rofl:

PS: no, no one get's the larger version because it is downright embarrassing :(

Now after cleaning each channel prior to integration and other cosmetic corrections.

It's still VERY short on data, but the potential is definitely there.

I don't miss the frustration of imaging one bit, although these days with digital it must be just so much easier than film was when I last did it. At least you got out there and got something.

(For the younger members here: Film was a means to capture images before Charge Coupled Devices were even an itch in Silicon Valley's jocks)

Nice one Lewis :thumbsup: glad you were able to do some imaging. :)

Cheers

I think it's really good Lewis. Which scope did you use? And what F ratio or focal length is it?

Scope: Old Faithful - Vixen FL102S
CCD: OLDER Faithful: SBIG ST-8XE with Astronomik filters

Scope was reduced to f/6.3 fro f/9


Got a LONG way to go on this one, IF I don't decide to finish off M78 again...

"Yes, it's gad awful" no its not....its a great effort for what you got Lewis.

Sorry to disagree - it is gad awful, but thanks for the morale boost :)

Here's the best I can do with the cruddy data.

Very nice. That's a faint one. :thumbsup:

Glad to see you got some Lewis!:question:

Worth keeping on with NGC2467, it's a beautiful nebula.
Here's what it looks like from my 1100D.
This is quite old data 1.5 hrs - 5 minute subs, from 2012, I plan to revisit with longer subs.

Cheers,

Justin.

I was amazed and delighted to see how much H-a is in the neb. Lum is VERY dull, but Ha just jumps out. OIII is smallish, but SII is minute - just the little "cross" structure near the bottom.

A gorgeous nebula. Thanks to Stu for the inspiration to capture it. Will keep going with it, hopefully with a slightly better framing now I know it's full extents.
