Hi
It was one of those nights again last night, trying to decide whether to try some imaging or not. There was patchy cloud dotted over the sky with a few clear patches and occasionally some thicker patches drifting in occasionally, I have seen this before where I live and sometimes it is worth giving it a go even if only to salvage a few frames.
I decided to give Van den Berg 142 (Elephants trunk nebula) in Cepheus a go as it had just risen high enough over my neighbours tree. I managed to get 15x10 minute unguided subframes with the TMB 115/Starlight Xpress H36 on my Paramount ME. Unfortunately 6 of the frames had to be junked because of cloud damage and the last two frames because "good light stopped play".
I did a sum combine and 0.8 gamma stretch in Maxim DL and then transferred to CS2 where I used 3 iterations of curves and local contrast enhancement using Noel's tools.
I have enclosed the widefield version and also a cropped closeup. I was having a further play with Noel's tools and added false colour, these can be seen on my website

in the image gallery under nebulae
Considering the clouds and short imaging time I am quite pleased with the result
Thanks for looking
Regards

Ah the fickle weather :rolleyes:

Nice result none the less, I love Ha images.

What do you think of the H36? I was considering one of those then went with the ProLine 11002.

I had a look around your site Gordon and I liked the Astronomy Jokes :thumbsup:

"If you find it difficult to look at Uranus...look at Mars then, she won't mind"... :doh:

Hi Mike
Thanks for the comments, I like Ha as well, at least you are not restricted by moonlight and light pollution, the only downside being that you have to use longer exposures. The H36 is a great camera, it only has 2 flaws as I see it
1. No control over cooling
2. Not as sensitive in quantum efficiency as the FLI equivalents
The problem was that I really wanted a proline 9000 but in the uk it cost almost £9000 which is twice the price of the H36 and I just couldn't justify the cost. In the future a definite possibility though.
Love the joke by the way, do you mind if I put it on my site?
Best wishes
Gordon

Hi Gordon, love the image! Don't think I've seen this one before.

10minutes unguided exposure... now that's the kind of polar alignment and guding accuracy I can only dream of:D

Very nice Gordon, there some lovely detail in this one. The globules at the bottom really jump out.

Cheers
