The Iris Nebula, also known as NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158. It lies 1,300 light-years away and is six light-years across. (from Wikipedia)
I have already photographed this area of the sky but using a DSLR camera and my previous telescope not optimised for AP. Now, using a dedicated deep-sky camera and monochromatic imaging, the result is much better. However the light-pollution makes still challenging to show the dark details without increasing the noise.
The Iris Nebula - bright reflection nebula in the constellation Cepheus
Image Integration: 6 hours
The "Leo-Triplet" - Galaxies about 35 million light-years away
Image Integration: 0.5 hours
The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.
The location of the famous Leo Triplet on the spring sky is not so optimal from my observing site and therefore not suited for long imaging projects. Despite of this, I wanted to take a short "visual" trip to this beautiful group of galaxies. Only 0.5 hours of exposure was possible, but I still processed the data. Some fine details are well visible in the structures of the galaxies.
