Polaris – the Double Star

I’ll be honest, I really never viewed Polaris under any magnification before. I’ve always used it as a guidepost to align a telescope or other piece of astronomical equipment. While recently setting up my pier and Meade telescope for the first trial runs, I focused the scope on Polaris to begin alignment, and snapped a few quick pictures. That is when I noticed a little companion star right next to it! Low and behold, Polaris is a multiple star system with an 8.7 magnitude companion (see image in the two o’clock position). Polaris actually has another, closer star, designated Polaris Ab that amateur scopes can’t resolve. You can see a Hubble view of this star at:

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.
