Supernova SN2017eaw in the Fireworks Galaxy (NGC 6946)

I had some time last evening to collect data on the Fireworks Galaxy (NGC 6946) knowing that there was a recent supernova discovered in it, actually back in May of this year. I had the opportunity of collecting data on this galaxy in the past (2015) so I was able to compare the views and see the supernova (see pic) using my own data.

The bottom photo clearly shows the supernova with a distinctive reddish hue.

Tech Specs: Meade 12” LX90 + Antares Focal Reducer +Canon 6D, guided using a Canon 400mm lens and ASI290MC ZWO camera. 24 x 60 second subs at ISO 1600, 3 x 60 second darks and 3 x 1/4000 second bias. Date: September 10, 2017  Location: The Dark Side Observatory, Weatherly, PA.

Andromeda Galaxy System

Having not had a lot of telescope time during the summer months, I find myself reprocessing data collected in the past. This is a reprocessing of the Andromeda Galaxy region including insets of the two brightest satellite galaxies, M110 and M32. This is from data collected from 2015-2016. The wide-field view was collected using a Canon 6D and 400mm lens, the inset images were captured with my Meade 12” LX90 telescope.

You can find additional details on these images on the links below:
