Hi Hugh,
Yes agreed on both counts. The Atik 314L+ was my first astrocamera and has been very effective for spectroscopy (decent resolution), photometry (16 bit linear response) and astro (works well and straightforwrd to use)
Re the Adventurer PEC quite agree I was a bit sloppy and should have said 2" guided. Theres an assessment of guided vs unguided with the Adventurer at
http://www.cloudynights.com/topic/46...r-first-light/ . The native PEC on his lightweight tripod and heavy camera with no counterbalance rig was 23" P-P and guided it was 2" rms.
I'm going to be using a steel tube eq3 with a very solid adaptor, light weight camera, balanced load and OAG guiding so I'm hopeful that I'll reproduce the 2" but can't be sure it will work - I'll let you know how it goes.
All the best, peter
