    Thank you for that. I have a Baader MPCC and I'm told I won't be able to get that to work with an OAG fitted to a Nikon. I think you are right - I will need a thin OAG. I'm still not sure about the coma corrector I should buy. The Baader RCC will apparently work if I can get the adaptors I will need but some threads seem to inicate that collimation and/or tube flex is a problem with the RCC.

    Hi Does anyone feel able to recommend an OAG + Coma Corrector combination that achieves the correct spacing and good reliable results when connected to a Nikon DSLR? Cheers Mike

    Thanks for that. Yes the whole set up is pretty over-engineered - very solid indeed. Cheers

    The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

    Thanks. The skies here are not too bad. We are at around 700m altitude and 100kms from the centre of Sydney. There is a thin strip of housing and small villages/towns that follows the road as it winds up the mountains and is the main source of light pollution here. The main problem I have is the humidity is very high at the moment and and as soon it as starts to get dark we get low altitude cloud formation that starts of wispy but gradually builds to create a continuous blanket of red. Oh well at least there are moments of clarity and it should dry out later on into winter.

    Thanks. Still working on the processing and I hope to get the autoguider working soon but I was pleased with it as a first attempt. Cheers Mike

    NGC 3372 Collected my new Skywatcher Quattro 10" f4 Newtonian yesterday from Bintel in Sydney. This is the first scope I've owned since the Tasco 60mm alt/az I saved up for when I was 12. I had already collected a AZ EQ 6 last Thursday and spent the weekend understanding the mount, sorting out alignment and playing around with a camera fixed to the mount and stacking frames using free software I found on the web. Yesterday I set up the scope and was ready for when it got dark... I captured about 140 images but high level cloud ruined most of them. The image below is a stack of the best 30 or so. My main hobby is photography so I framed the image to match the others on my online gallery. --------- Skywatcher Quattro 10" f4 Skywatcher AZ EQ 6 GT Baader MPCC Mk 3 coma corrector Nikon D300 (unmodified) 30x30sec ISO800 unguided
