Thanks again, Chris. I took a look at your image and it is indeed very
good, IMO. May I ask what size scope, exposure times, camera, etc?

The image was made with a 16" DFM RC, using an Apogee Alta U47 1Kx1K
back illuminated camera. The image is a stack of ten 90-second frames.

If yours are that, I can only imagine what it will be for the puny ETX. I
suppose I could stack luminances over many nights as long as the SN
brightness remains, but this would take too much time. Also, not having
gone the DSO astrophotography route before, I'm new to dark frames, flats,
etc so that's only going to cut into my timing.

So, this time at least, it looks like I'll just admire the work of others.

Thanks again for your time and response.

Ron


BTW, would you or anyone else here happen to know how long a SN like this
will remain so before fading into oblivion?

This is a Type IIP supernova which peaked about a week ago, at ~Mv
12.7. It's currently around Mv 13, and this type of supernova will
typically show a very slow decay of 0.0075 magnitudes/day for quite
some time- probably another three months or longer.
