Carinae Nebula 10h 45m 59.52 bright diffuse nebula surrounding n Carinae easily visible with the naked eye. Discovered by Lacaille 1751-52. This giant diffuse nebula is one of the largest H II regions (composed of ionized hydrogen gas) in our Milky Way (http://www.seds.org/messier/more/mw.html) galaxy. The star forming nebula NGC 3372 has produced the very conspicuous peculiar star Eta Carinae (http://www.seds.org/messier/xtra/ngc/etacar.html), which is among the most massive and luminous stars in our Milky Way (http://www.seds.org/messier/more/mw.html), and perhaps in the universe.
Star forming region and its complex structure of bright area of gaseous emissions and dark absorption lanes bears examination with a wide range of apertures, it contains various star clusters and several double stars. Distance 3.4 kpc (10400ly)


Note: What intended to be a session on NGC2070 after 2477 but by 12:00 midnight it turned into Eta as 2070 was too high in the sky and it became a back breaking job trying to line it up and then focus on 2070 so I went for Eta instead.

Nice going Trevor, May I ask why you're imaging with the 120 F/5 acro rather than the SV80ED? The SV80ED would produce a better image, and a wider field of view....

[TrevorW]

Just wanted to give it a try so it didn't feel neglected, it's been sitting idle doing nothing for sometime as I've rigged my 10 x 60 finder as a guide scope atop the SV80, so the 120 doesn't get used much these days.

Cheers

Nice shot, Trevor....the achro isn't doing such a bad job at all. But the ED is the better scope. I think there's a strong bias against using achro's for imaging...and fair enough, given the CA you get in them. However, some achro's are far better than others and the Skywatcher f/5 120mm looks like one of the best of them in terms of optical performance.

You're getting there Trevor ! I also have a few scopes lying around gathering dust since I got the FLT110.

:thumbsup:

[AlexN]

Yeah... I'd keep the 120 F/5 for narrowband work for sure.. Im really regretting selling my 152 F/8, as it would have been a beastly refractor for NB imaging... :) oh well.. live and learn I guess.. :)

Steve - I bet your scopes have been gathering dust after receiving the FLT110 :D My scopes all get used about equally.... as they all do very different duties at very VERY different focal lengths..

[bluescope]

The FLT110 is a very convenient size ( 6.5kg and 770mm long ) with excellent optics, much easier than dragging my 254mm ( 15kg - 1200mm ) newt outside :whistle:. When I get my observatory setup again it may be a different story .... we'll see .... I doubt it though I love my apo.

:thumbsup:

Nice Trevor. Info nicely sets the scene too.

Thnaks guys for the feedback I may have overdone the processing but attached is a slight variation

Good effort Trev!
