Wow, what a difference! SS Auriga is now so bright I didn’t recognize the field at first. It’ll be neat to watch as this star fades back down to magnitude 16ish before it does this all over again.
By the way, this was perfect timing. It wasn’t forecast to be clear this evening, but the clouds departed earlier than expected today and it stayed clear and bitterly cold. Much to my surprise I found a little box from Astrovid waiting for my on the table when I got home from work; my V photometric filter arrived! I mounted it in one of my spare filter slides and removed the IDAS LPS-2 from the nose piece of my DSI Pro II. As expected I had to tweak the focus a bit, but since my SN6 has an electric focus drive that was not a big deal. I was pleasantly surprised to find the removal of the light pollution filter didn’t have any adverse effect on the image since photometric images aren’t stretched the way deep sky images usually are. Also, the image is a teeny bit darker than a typical luminance image, but not by much. Using a 30 second exposure I was still able to easily reach 16th magnitude, though I may increase the exposure time a tad to follow SS Auriga all the way through its next minimum.
