just for fun I combined this H alpha image with OIII data I acquired last year.
This was only 50 minutes and of poor quality -star trailing and noisy-but still, here is my first colour mapped image (OIII data contributed to blue and green channels, H alpha data to red and 20 % to blue-synthetic H beta )
don't have Registar so alignment was manual; also
different star sizes in H alpha and OIII means full res image is pretty ordinary

Thoroughly enjoyed the Ha image. The culmination of 4 hours data provides a smooth, noise free appearance and is a credit to your efforts. Well done.

Thats a fine effort, you certainly extract the max out of the gear you have. Good detail, tastefull processing and excellent guiding for such long exposures.
Cheers

Narayan, I love the black Globules in your cropped image
You have certainly got a lot of things happening correctly: Tracking/Guiding, Focus, contrast etc etc
Very nice work.

Both are very nice, Ha is funny looking huh? I like the ability to image even when the moon is about. Nice job of combining the two as well.

Thanks all for your interest and comments. Not only does narrow band allow imaging on a moonlit night but even on a new moon or third quarter night, one can image from home-and that's two or three hours that can go to exposure instead of travel to a dark site.
