Hi Rob, I don't know of any specific side by side comparisons of the Star Analyser and the Rainbow device but physically they are similar and comparing the...

... Probably astigmatism but its very time consuming to get good focus with DSLR as unlike CCD/webcam there's no instant feedback or pixel brightness reading...
Did some spectral starhopping in Cygnus tonight via Meade LX200 and Megastar. Bagged 2 WRs + 1 Mira + 1 Carbon star in a half degree field centred RA20h 10m;...

Hi. I'm new to the group and have been through the archives looking for an answer to my "beginner's" question (novel concept to look there first) but haven't...
Hi John and welcome to the group, I am not familiar with the DSI or the Photshop FITS plugin software unfortunately (My older version of Photoshop does not...
Hi Robin - I posted my URL for my "Spectral hotspot in Cygnus" on CloudyNight Forum {so pleasantly civil compared to other open astronews groups] with a...
Hi - Did anyone record Nova Scutum 05 spectrum? If so is there a URL[s] for it? Tried this evening [ok belatedly!] but nothing found in slight haze low in...
Thanks, Robin. I was trying too hard to retain the color image. Once I switched to a FITS "mono" I was on my way (the learning curve is pretty steep using...
After seeing everyone's nice spectra on various websites, I knew basically what I was shooting for. Instead of posting the image, I'll describe the spectra so...
Then again, if it was light pollution, then shouldn't the entire sky have that "peak"? It should have dissappeared when adjusting the background. So I'm back...

Hi John, You are right about light pollution. If you are not using a slit, the sky background just adds uniformly at all wavelengths. You can see the effect on...
