M20 The Trifid Nebula

[cometcatcher (Kevin)]

Continuing to experiment with the 8" F10 SCT. This is M20 The Trifid Nebula, or angry cat nebula from some angles. z

Needs at least 10 hours to smooth out the noise but I'm still just mucking around at this stage to see what I can get.

Meade LX90 ACF 8" F10 SCT, Canon 1100Dfs, 600x30 seconds guided with PHD on a HEQ5 Pro.

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764. Its name means 'divided into three lobes'. Distance 5200 light years.

Another nice shot there Kevin with a good colour balance but like M17..?.. longer subs perhaps..?

Needs longer everything Mike. DSLR's and F10 are not the best match. I don't personally recommend the combination to anyone else lol. DSLR's like F4 - F5 best. I'm just mucking about.

Not a bad shot for just mucking about but it does look a bit noisy. Maybe a mild noise reduction if you don't want to go to longer subs?

Well done, Kevin. You've got excellent resolution there. Each of the two very bright stars on the upside-down tom-cat's nose is revealed to be a triple, comprising a very close binary and a fainter outer companion. That takes some doing.

The DSLR has let you capture the reflection nebulosity beautifully. The famous Herbig-Haro jet (the thorn in the pussy-cat's ear) and the cometary globule next to it are only just there if you know where to look.

Already has gentle noise reduction. I don't usually like using it. The best noise reduction is more time. The thing is, I'm pretty harsh on processing. If I can't see grain, I haven't made it bleed hard enough. Some people like em buttery smooth, not me so much.

Thanks M&T. The core was masked out when processing the rest so as not to blow out the central stars, though with shorter subs I could have done even better. A bit like processing the Orion nebula.

Nice work, Kevin! I'd like to see the jets stand out a little but you are pushing he bounds of what is possible, as usual

Thanks Rick. Yes I would like a bit deeper too. The night time temps are creeping up now as well which will be hard on this non cooled camera. Things will get lost in the noise.

It's a new scope Kevin!

It's a nice shot for just doing some playing around. Nice separation of the central stars.

[cometcatcher (Kevin)]

It is Colin! The fun part is seeing what it can do. It's great for small bright objects.
