Reprocessed Eta carina heaps more detail

Hi all
Ive reprocessed an Eta Carina Neb shot I took a few weeks ago with the 6 inch f3.6 SN
6x10 mins ISO400. Baader UHCS filter and MPCC coma corrector. Hutech modded 350D.
Taken from my suburban back yard where the LMC is only just visible to the naked eye.
Not bad for a 20 year old telescope and an even older mount. Both corrector plate and main mirror of the SN are ordinary green plate glass, what was at the time a "cheap n nasty" scope that only cost a few hundred dollars, very cheap back in the 1980's. Look how cheap standard newtonians are today
I should point out a few modern additions like the camera of course and also the q guider camera but that still requires hand guiding a star image on the laptop pc.
The whole shooting match, including the Hutech modded camera and laptop cost me less than the cost of a STL11 on its own with no scope or even a filterset and wheel

One final advantage. If necessary it can be used in the field without a PC. I used to manually guide with an illuminated recticle before the Q guider came along. The drive corrector that runs the mounts RA drive draws about 0.6 amps 12V, so even a small SLA battery lasts a very long time in the field.
