ngc 7814 in Pegasus


Recommended Posts

Last spring I bought a new telescope (a refractor at that) for wide fields, but I couldn't test it then. So this is almost first light. I wanted to see what this telescope can deliver, and I must say, I'm not very impressed. The stars aren't round to the corners and there is a horrible blue bloat. The first night I collected data for this image, I didn't refocus before switching to the blue filter . (Hey, I'm a reflector guy. I'm not used to having to refocus.) The second night I refocused with the blue filter in place and collected new data. Even the green subs were below par and I used only 13 of 21 collected. For this reason I didn't even bother collecting luminance data. I created a synthetic luminance instead. What I am pleased with is the sensitivity of the ASI294MM which pulled out quite a few distant fuzzies from the limited data.

  • Red: 20  4 minutes
  • Green: 13 x 4 minutes
  • Blue: 30 x 4 minutes

Total integration time, just over 4 hours with the moon at 80%.

I have also used this scope together with a Star Analyzer 100 and have started playing with spectroscopy. I will probably use the scope for that and for wide field Ha objects. The Pelican nebula is very nicely framed with this scope and the 294.

Well, can't even say I'm an amateur imager or something, but that is a great photo. In my view at least..

Kinda plays with your mind this thing. Makes you wonder about stuff haha 😄
