Amazing tutorial! I’m about to set a SA200 in my EFW, and now in the best position to process my first data. If only the weather agrees, in the French southwest… Thanks again!
Excellent presentation. BASS also has all this step by step and more under help, for new viewers,but I like starting with the video first for an overview. I was completely unaware of siril and imagej.so thanks. I used the pixel tool in sharpcap for focus previously. Hopefully maybe you could do one on slit spectroscopy. I’m finding guiding to be troublesome there. Much appreciated 😀
Excellent! Thank you for sharing this and great timing. I will give a presentation of doing Spectroscopy with Seestar at TAIC tonight, and have been using BASS for processing. May i reference this video in my talk?
Thanks for the question @ravnica1 - Typically you would use the instrument response from a nearby Type A or B star (that has these Balmer lines; like Sirius or Vega) to correct the instrument response the target you are after that same night (lets say Betelgeuse or Uranus). The instrument response corrects (contains, models) the atmospheric distortions, optical efficiency and your Camera quantum efficiency. So in order to get your target identified well, you always shoot a nearby Type A,B star on the same night.
Thanks for your video! Very usefull for a someone like me wanting an overview. I am still unsure to go down this route. I would like to know if, from the scientific point of view, this type of slitless spectroscopy has any usefulness!
Probably my familiarity with SIRIL from Astrophotography. But I also really enjoyed the speed of working with SER files. I did not find a way to use SER files in BASS (individual FITs work great!). To make it work in BASS you could export the individual FITS subs from SER (e.g. using SIRIL), and then do the stacking in BASS instead.

Outstanding presentation!
Many thanks for sharing this well structured presentation.
Looking forward to the next one.
Hi. Thanks for great video. How do you get rid of reference spectrum? I can't figure this out on my own.
Ty for sharing your experience
Very nice presentation!

Absolutely! Looking forward to your talk tonight!
Nice, how would you obtain and apply instrument response for a spectrum of a star of a different type let's say Betelguese?

Just curious why you didn’t do your preprocessing inBASS?
