Description

M1 with 8" F/4 Newtonian and a GSO 2" Coma Corrector (increased my scope's focal length to 915mm.) Also in the mix was a Lumicon Deep Sky T-adapter mounted filter and an IDAS-LPS drop in filter both used simultaneously. I had to use ISO 3200 and 3 minute sub-images to get the histogram off the left side with Lumicon filter. Guiding with a new home-made 50mm finder and an Orion SSAG arrangement. Still having trouble getting images without tracking errors with exposures longer than 3 minutes, which is why I went with ISO 3200.
