Re: DSLR Camera

Hello John Cant go far wrong with a Canon EOS 1100D. The standard lens 18-50 lens is fine for general photography but as for other lenes such as telephoto's I would suggest buying old M42 screw thread lenses off EBay .I did this and it was amazing how cheap they were. Youll need a M42 adaptor ring f...

Re: Two Very Different Nebulae

HI Brain, The RA drive on my EQ5 mount is very old and very basic,it plays up sometimes especially after slewing and takes a little time to take up the slack .Also it has to carry a rather heavy DSLR and I'm not always conscious enough in balancing the tube properly between shots.Both camera and mou...

Re: M11 Wild Duck 02.10.16
