Hi to all, here I am with another image taken last months with the TEC 140. This time it is a very seldom imaged object in Canis Major, Sharpless 308.
Despite this nebula is a giant bubble larger than the full Moon and very conveniently located for southern observers (it passes almost at the zenith), I found very little images around the net, one of those the fantastic image taken by Don Goldman that gave him an APOD some time ago. I believe this is the first post of this object in this group if I am not wrong..
Again this is a combination of narrow band filters and RGB colors (I don't like mapped color images) and here the contribution of the OIII filter is essential. Unfortunately I was not able to collect as many subframes as I wanted, in particular for the OIII, this because of the set up problems I have already mentioned before. Therefore this image is much noisier that I wanted.
Total exposure was a little over 15 hours.
I suggest the view of the zoomify version to full resolution at full screen. If you use firefox 5 you will also enjoy the color management (the color profile is embedded in the images.
Hope you will like this image. I really hope that somebody of you with larger telescopes will give this nebula justice next winter
Love it Marco. It's so delicate and must be a real task to find without perfect pointing. The sublety of the Ha in the background is superb.
Beautiful image.
Thanks Doug, actually this object is pretty easy to be found thanks to the bright yellow star at its base (Omicron CMA), another reason that doesn't justify the little images around..

This might be worth a crack with the AG12

Thanks Mike, with your new fast Newtonian you should get an excellent s/n on this object with a fraction of my exposure time. Consider also that the size of this bubble is close to one degree, a perfect fit for your FOV..

Thanks for pointing out this virtually unknown object so beautifully.
Greg.
Thanks Greg, I hope you will ive it a try with your CDK17 reduced, you should be able to get a superb view of this faint bubble..

Mate, I have looked at your images on the glittering nights website.. they are absolutely amazing the colour depth and detailed captures is unreal.
Apart from decent optical equipment, is the camera you use particularly different to other cameras? i notice it is very sensitive to reds and blues
obviously its miles ahead of DSLR's etc but is it a specific camera designed solely for astro etc, and is the kind of camera you need to mortgage you house to get or can they be bought for a few grand?
ive checked out their website, there is little information on it.
Wonderful image Marco. So fine a detail. Excellent presentation.
Thanks Paul

Thanks Steve for the nice comments. There are several factors that contribute to the final result, namely the equipment used, the sky quality, the integration time and the way to process.
Indeed the camera I use is dedicated for astrophotography and it is on the high range in terms of cost. To have an idea check the website of one of their distributors: http://www.optcorp.com/ProductList.a...9-320-322-1028
Price range is in line with other equivalent products in the market using this large format CCDs..
Lifting the bar alright, to at least a near Earth orbit
