First spectra with Star Analyser

Well, it's not really much to show, especially with the amazing results people have been sharing of Nova Del, but I'm fairly pleased with it.

It's actually my third attempt, first couple of efforts were with a DSLR which I need to use with a barlow to achieve focus on my scope and hence pretty miserable results, plus the setup gave me about 4 angstrom/pixel.

Tonight I tried it with my QHY5, a huge improvement. Much broader response curve, able to achieve focus without a barlow so the scope running at f/5, and the spacing gives me a more reasonable 12 angstrom/pixel.

Getting focus and framing with the dob is infuriating. One day maybe I'll own a tracking mount

10" GSO dob, QHY5 mono and a Star Analyser SA-100.
