I have long wanted to image this beautiful region of the sky, but I didn't have a good OTA with which to capture it. With the addition of the 200mm Canon lens to my equipment list, Rho Ophiuchi was finally within my reach:


Posted Image

High Resolution version and more image information available at http://www.astronome....php?c=17&p=494.

This image was made from a stack of 123 subs of 5 minutes each at ISO 800 taken with a Gary Honis modified Canon 450D (Baader Mod) and a Canon EF 200mm f/2.8L II USM at f/3.5. The camera was piggybacked on a Celestron C-8 and guiding was with the C-8, an ONAG on-axis guider, and a Lodestar autoguider.

Thanks for looking!

that is a beautiful area that just stirs the soul. The colors seem a little to saturated, but still beautiful. I have been wanting to spend time on this one myself. I thought in the 50mm to 85mm range for a wider fov. The longer I do AP the more I'm amazed. Thank you for sharing this image.

Wish I didn't live too far north to capture this stunning part of the sky. Alas, I'll have to experience it through other's images.

An amazing image Scott! Lots of subtle dust in there. I agree with a few others and it seems the saturation is a bit much for what I prefer(seems to be the blue that is pushed). Still an amazing image.

Very nice Scott, there are a lot of nice wide field targets out there for a 180mm or 200mm telephoto lens. Looking forward to seeing more widefields.

Thank you so much for your very kind comments. This was a very challenging and fun image to process. The colors in this area are so varied, and there's just about one of every kind of object imaginable. I understand where some feel its oversaturated - I don't think I'd entirely disagree. I've tried toning down the saturation, but it just didn't have the pop I wanted. So, I left it as a saturation monster (my personal preference).

@Mo - your 50mm and 85mm plan is a great idea. This image will eventually part of a 50mm composite for me. Rho Ophiuchi is the highlight of the area, but the entire region is quite incredible.

@Warren - yes, I agree on lots of great ~200mm targets. I'm looking forward to grabbing all the great summer targets over the next few months.

Awesome!

I have to travel a bit further south to really capture this beauty. At a mere ~19deg ... *sigh*
