Eastern Veil narrowband H-alpha with Esprit 100 triplet refractor and ASI1600MM-C

NGC 6992 Eastern Veil supernova remnant
I've had more clear nights to use my new Sky-Watcher Esprit 100 triplet telescope. I've been collected HaRGB data between July 28 and Aug 7, on the Eastern Veil nebula NGC 6992. NGC 6992 is one part of the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant (SNR). These are [...]

It's an exciting end to the month of June as my newest telescope addition arrived! I have used many different makes and designs of telescopes over the years. All of them were good and I have enjoyed using them. Some better than others. A few I still have even. I felt it was time to [...]

M31 90min LRGB test using ASI1600mm-cooled CMOS camera

M31 90min LRGB test image with ASI1600mm-cooled

I performed some more test imaging with the ASI1600mm-cooled camera. This time I centered the telescope and camera on M31, the great Andromeda galaxy. I have imaged M31 before a few years ago using different equipment. This galaxy is a popular target at this time in the northern hemisphere when it rises high in the […]
