Welcome to the RSpec spectroscopy forum, hosted by Tom Field, the author of the RSpec astronomical spectroscopy program: link ( https://www.rspec-astro.com ). All of us here are big fans of astronomical spectroscopy. It's fun, exciting, inexpensive, and not hard. And best of all, it's hands-on science! This is a friendly, online community. Whether you're a beginner in the field or expert, your questions are welcome. Need to contact Tom? Contact form: link ( http://www.rspec-astro.com/contact ).

What are we measuring? 3 messages
A fairly fundamental question that has only just occurred to me.... when we measure spectra using a CCD or MOS detector presumably we are measuring the number of photons, not total energy, arriving as

A type IIP supernova in NGC4545
At mag 16.5, the type IIP SN 2022fuc in NGC4545 is probably too faint for a spectrum with most setups but I thought I would post about it as it shows the interesting differences from type Ia SN 2022hr

supernova SN2022hrs bright in NGC4647 34 messages
supernova SN2022hrs is currently mag 13 in NGC4647 and well separated from its host galaxy so a good target for the Star Analyser (use a cooled camera and low dispersion.) https://www.rochesterastrono

My version of SN2022hrs 9 messages
:-) :-) Hi, just started to take a wide FOV image of the SN2022hrs between M60 and NGC 4647 and of course a satelite had to cross exactly on the Super Nova. Tomorrow I can post the finished image.
