This four panel mosaic gives an incredible widefield view of one of the most colourful regions in the night sky. A collection of intricate dust clouds, reflection, emission and dark nebulae and background globular clusters makes this a fascinating area. All data captured previous summer (end of June) in Mt. Parnon Greece @ 1430m. We finally found some time to process and merge all of them in one picture. Luminance taken by Angelos Kechagias with an Atik 428EX on a Nikon 50mm Lens, RGB taken by Evangelos Souglakos (me) with an Atik 4000 on a Canon 50mm Lens. Both lenses were stopped at f/5.6.

Hello everyone, Last wednesday, I tried my first shot with an Astrotrac, which I borrowed from a friend before making the jump and buy one. And I must say that I'm quite amazed by its tracking capabilities, even without an autoguider. I know that the lens I used has only 85mm of focal length, but I only got a 5 pixels drift during 45 minutes of imaging : that's quite impressive Enough chitchat, here are the images : 5DmkII, Astrotrac, 85mm f/4.0, ISO 800, 14 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. From the Southern Cross to Eta Carina 5DmkII, Astrotrac, 85mm f/2.8, ISO 800, 9 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. Pipe, Trifid and Lagon nebulas, with some Barnard 5DmkII, Astrotrac, 85mm f/2.8, ISO 800, 30 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation. Rho Ophiuchi A mosaic of the last two images Click on the pictures for a larger version I hope you liked them ! And if you're on the fence to buy an Astrotrac, just do it, it's an excellent piece of gear. Clear Skies
