M37 RGB

[Graeme Coates]

I grabbed this set of subs on night if 5th Nov as a quick image after working on the bubble. 35 min in RGB at 1x1 bin (7x5min subs).

Processed in Pixinsight - the RGB process is not so hard, the automatic colour registration tools work quite nicely, and makes stretch preserves start colour well. I particularly like the deep red star below (south) the cluster.

That's a really nice image Graeme. Good to see you are getting to know
your way around PI. Are you using the trial version or have you 'doshed
out' for a license! Its quite expensive I believe.

That red carbon star came out well. There's another one close to Orion -
W Orionis (HIP23680) which is mag 6.1 so quite a lot brighter.

I remember many years ago attending an Astrofest in Kensington where
David Malin was the main speaker. After his talk I showed him a
ciberchrome print of the Orion constellation which Konrad had made from
one of my transparencies -

David pointed out that star to me on the photo and said it was a carbon
star. I would never have known that!

Cheers,
John

Still on trial until Xmas eve (45 days is reasonably generous, and I have data to play with and can easily lay my hands on more). Will decide nearer the time, but I rarely buy much expensive software so might go for it (licences are cheaper when you work in academia!).

(Should clarify that PI isn't cheaper, but lots of other things are
(OS, Office, Photoshop, etc...)
