    M15

    M15 from the 28th, 144x60s subs, always difficult to process colour with so much LP but PI's photometric colour calibration helped make the task much easier.
  2. Thanks for all the advice, very helpful, I suspected the Astronomic was too good to be true. The Baader filter is probably worth a try at £200 for a 1.25" I think. Rob
  3. Looking to try some bicolour images as my light pollution is much worse sine the installation of LED street lighting nearby and wondering what the best value OIII filter is for CCD. I already have an Astronomik 12nm Ha filter, would an Astronomik OIII be worth getting? Thanks, Rob
  4. The thread on the clamps are M8
  5. I use a 13/16" socket seems to fit quite well though I'm sure they will be metric so I suppose 20 or 21mm would be correct. I'll have a look at the thread in daylight tomorrow unless anyone jumps in first.... Rob
  6. Nice setup, been considering one of these so I'd be interested to see how you get on with imaging through it. Is the steel tube rigid enough? What gauge is the steel? Thanks, Rob
  7. Thanks for the tips, glad to know I have the correct bar. Rob
  8. OK I'm new to dovetail bars Strange though that may seem ☺ I have just took delivery of an eq8 mount and bought a Losmandy 15" type d bar for it. I have fitted the bar on and was surprised to see a gap between the mount and the bar of a few mm. Is this normal? Have I got the right bar for the mount

    Barnard 1991 to 2011

    The motion of Barnard's star between 1991 and 2011. Images take through a 14" reflector on film and with 3 different CCD's! Motion is 10.3" per year, total movement over 20 years is 3.4 arc minutes.
