This past Sunday, February 26, 2017, a fellow member of the Roanoke Valley Astronomical Society, Bert Herald, invited me over for some observing. Bert has recently purchased an impressive Celestron Cassegrain telescope and tracking mount to do astrophotography.
He has just recently moved from afocal imagining, using an iPhone, to the big leagues of DSLR astrophotograpy. The evening started with a complicated and sometimes frustrating polar/5 star alignment which gave me a greater appreciation for the complexity of these advanced telescopes. After some initial difficulties with alignment, later in the evening Bert was able to get some nice exposures of NGC 1983, the Running Man Nebula. He described overcoming some difficulties with the tracking system for this observing session and the process of capturing the nebula:
Tracking continued to suffer even after a second round of alignment! But it was good enough to capture a set of 5 30 sec exposures. I stacked them and briefly edited…
The result of his efforts is an impressive image of NGC 1983, particularly for someone new to advanced astrophotography.
