The Crab Nebula ... Messier 1
(Click on Picture for larger view)
Added April 21, 2019 ...
The Crab Nebula is in the constellation of Taurus the Bull and is the remnant of an exploding star (supernova) that occurred in 1054. What we see today is the outgassing of that explosion. It is about 6,500 light years away. I took this image April 21, 2019. This nebula is medium high in the WNW at sunset in mid April. I started shooting once the twilight ended at 9:15 and ended at 10:11 after which the object fell behind the trees. Click on pictures for larger view.
<-- This is the full view at the f/10 setting of the telescope and the Canon 7Ti camera.
The picture above is a cropped view of the full view image giving it a larger apperance in view, but they are both from the same exposure, which was 54 minutes.

Added Jan 14, 2018 ... Heavenly Backyard Astronomy Video #1
This is my first edition of "Heavenly Backyard Astronomy". In this video, my target was the CRAB NEBULA in the constellation Taurus the Bull which is the remnant of an exploding star (supernova) that occurred in 1054. What we see today is the outgassing of that explosion. It is about 6,500 light years away at a visual magnitude of 8.4. This image was captured Jan 13, 2018, in my backyard using 86 X 60second exposures at an ISO of 3200 on a Canon T2i using an Orion CLS (City Light Suppression) filter attached to the prime focus of my Celestron 11” Edge HD f/10 telescope. Outside temperature was in the upper 30s.
