This image was taken at the Snake Valley Camp last weekend. A very tight fit and mostly experimental. Two versions, subdued and contrasting?
The sub frames are a little under exposed and too few to really make things pop. A little StarTools magic (not the Magic module) teased out the detail, while doing a very good job on the noise.
Preprocessing in Pixinsight and post processing in StarTools, using the additional Luminance channel technique to allow further stretching of the colours.
The bias and dark frames are twelve months old and were taken with my regulated cooled Canon 1000D, at -5C. Pretty good consistency. The camera maintained -5C +/- 0.5C all night over the weekend.
Despite heavy dew both nights, the camera and scope ran dew free. It was a delight to see the dew controllers inside the camera and on the scope perform very well.
I have a bit to learn about keeping bright stars like Antares under control, and, I have a faint suspicion that several of the images may have been taken with the focus mask in place. Rather than discard them, I am prepared to put up with those big spikes emanating from Antares. But there is room for improvement.
hi Rowland,
nice one - I love this area of the sky. think i'll have a crack at with my camera piggybacked on the scope this season. I prefer the first version but perhaps something in the middle?
the camera mod sounds interesting - good to hear the gear was running well.
cheers
Well done Rowland, an excellent image.
I definitely prefer the first version Rowland, a lot "punchier".
Are you able to mask Antares a bit more to see if that can make any difference?
Bo
lovely work Rowland. Your ongoing work on this area of the sky has been inspiring me to spend some quality time there once the obs gets up and running.

Thanks Russell. It was an image of Rho Oph on IIS that got me into AP. I look forward to it every year.

I think you should be pleased with that result
Thanks Andy. It is well worth the effort.

Thanks Bo. A better mask should do it. But the response of the 60CB is quite different to the Canon 200mm. Need to work on acquisition for the future.

Great to see your gear working so well too.

Thanks Nick. Well worth the effort. The dynamic range and colour is extreme. Quite a learning curve.

Thanks Marc. It was a great time. Beautiful skies, but cold with heavy dew.

Thanks Goran. I might have overdone it a bit - always a work in progress.

Thanks Dunk. Subs 180 and 150 seconds, about half and half, 35 in total, playing around with exposure times as it was the first time I had used the scope.

Thanks Rick. You will not be disappointed. Very satisfying area to image.
Thanks Jo. It's great to have it all running well. I read your astrobin post about LRGB combination, adding additional luminance to the processed RGB image. It makes a huge difference. I will look for your 'cool' images on astrobin.
