Eta Carina & NGC4945
A couple of humble attempts from the weekend - whilst I'm waiting for my new toys.
This was shot with the WO 70mm scope, Televue Reducer, piggybacked on the LX-90. Focusing was with a Bahtinov mask - I don't think it was perfect with Eta Carina, but I was happier with it on NGC4945.
They were guided through the 8inch OTA at 2000mm focal length - the guiding graph was pretty erratic, but I wasn't prepared to spend a lot of time fiddling with settings when this will hopefully be the last time I image with this mount. (The periodic error was +/-20arcsec). The seeing was pretty average.
The camera is an unmodded Nikon D200 - 5 min subs. 20mins of exposures for NGC4945 & 35mins for Eta Carina. They were stacked in DSS with a dozen dark frames. I then stretched the image in PS and bumped the saturation for Eta Carina. Both are cropped.
Any advise is welcome.
Regards
David T
