  1. I read the same sad news. I've had an excellent G42+ mount for many years and benefitted from Andras's friendly, expert advice on several occasions. I think his company is a small operation, perhaps depending pretty much on him personally, so I'm not sure if there will be anyone ready to take over. I'll be watching the GTD web site to see if there is any news. Adrian
  2. I haven't tried it, but you might be able to do it with two adapters: a c-mount female to T-thread male, plus a T-thread female to 1.25" male. For example: http://www.ebay.co.uk/itm/Brand-New-T2-T-Mount-Male-to-C-Mount-Female-camera-adapter-/251175321713?hash=item3a7b374071:m:mfQNmf33aeyt0wne7jgl1oA http://agenaastro.com/blue-fireball-t-t2-female-m28-5-male-thread-adapter-t-03.html A cheap DIY alternative could be to buy an inexpensive c-mount lens to DSLR/ Micro 4/3 camera adapter and Araldite on to this an old 1.25" threaded filter cell with the glass removed http://www.ebay.co.uk/itm/C-mount-movie-16mm-1-2-Lens-To-Micro-M-4-3-43-M43-Adapter-for-Olympus-Panasonic-/322016427684?hash=item4af9acbea4:g:gLkAAOSwGvhT9CWZ Adrian
  3. Robert Gendler has a series of good articles on his website covering much of this, including: - basic process of combining L with RGB http://www.robgendlerastropics.com/LRGB.html - the more advance 'multiple luminance layering' method (adding the luminace in stages as Olly described) http://www.robgendlerastropics.com/LLRGB.html - adding in Ha to enhance images of nebulae. http://www.robgendlerastropics.com/HARGB.html Adrian
