Food for thought guys. Many thanks. And thanks for the FSQ narrative Olly; yes, very true. 2" filters are out of the question.
This is my imaging setup at the minute:
1. TEC140 > Atik460/EFW2 Astrodon 1.25" LRGBHaOIII. On MESU (with Meade 14" but lets forget that for this discussion). Observatory permanently based. Works brilliantly and I am not touching it.
2. Widefield > Moravian G2-8300, Samyang 135mm, Astrodon LRGBHa 31mm. All on a modded NEQ6. I love this portable setup and really like widefield nebula work. I can have rig running inside ten minutes from startup.
The cameras now belong with the two above rigs and when it is clear I am always imaging with them.
3. My FSQ85 does not have a camera. I already have the 1.25 filters that are a mix of Baader and Astronomik. . I am in no rush to do this and so I may wait for a QSI 583/683 to come up or maybe experiment with a CMOS camera. i even liked the Atik460 on the FSQ85. I am clueless really on the CMOS variants so was looking for some thoughts in that department.
