Traantula Nebula

2 x 10 mins ISO 1600 with UHCS filter.
Many thanks all
I use a 10 inch F5.6 newtonian on an astro optical supplies "Sampson" mount
This is it here http://www.users.on.net/~josiah/focuser/IMG_9932.jpg
I use Off axis hand guiding for imaging. The Baader coma corrector goes onto the 2 inch Focusser, the T ring and camera screws onto the coma corrector, thus the coma corrector acts as the camera adaptor allowing it to be attached to the scope. Focal length of the scope is 1400mm.
I cant wait till the moon is gone from the morning skies, I plan to get some shots of the Orion area like M42 and the Horsehead
The Coma Corrector is excellent, not removing most, but all of the coma I used to get in my scope

Thanks Paul
Ving ,the belt comes in handy to help me in carrying the tube from the garage to the mount each night . The mount is permanently set up in the yard, covered up fully with a whellie bin liner and a white plastic bin put over the whole thing to fully protect against the sun and weather. I cover the plastic drive wheel with thick rags to make sure no light reaches it, as UV lignt can deteoriate the plastic wheel. This way the mount is always polar alinged . Lifting the tube was a bit heavy so the belt comes in handy, especially to lift it onto and off the mount.
I bought the scope and mount back in 1986 for halleys Comet, the off axis focuser/guider was bought early this year.

Thanks Tony
The UHCS filter really helps with the Tarantula, as it is indeed so blue on DSLR images. The blue cast I get with the UHCS filter, when I neutralise the sky background colour, makes the blue nebula much more reddish, almost like having a modified DSLR
Yes I recommend using both the MPCC and UHCS on the tarantula with your scope, stay with the high ISO of 1600, try to go 5 mins if u can, that should be good with F4.5 You will love the results.
yes tony that is a prime example of excessive photon collection
Scott will probably repaint it one day when he gets his mirrors re alimunised and Sio2 coating put on them, at the moment he images with a hazy mirror. Still trying to talk him into that one, but now he has his optical gadgets he may rethink that (did you hear that Scott). he would probably get at least 20% more light throught to the camera. His skills are to be commended, bit of an unsung hero but he has the respect of our AstroSociety. He is a very modest guy, and easy to get along with and no doubt will one day gather all his images and publish them in a book, especially the planetery faint fuzzies he has imaged.
hehehe youre too kind lol
One of these ays I will have to get in touch with the optical coating mob Qi Chin I think it is, and see if they will do a overcoated silver coating (98 to 99% reflective) on both primary and secondary (if I can afford a silver coat that is hehehe). An xtra 10 to 20% light wont go astray
