The Baader adapters is allowing me to use a 13mm backfocus ccd camera or a 6.5 mm backfocus monochrome cmos and preserve the 29mm +/- 1mm backfocus RASA 8 requirement.
A big thank you to Ken at
www.All-Startelescope.com (baader components) and George at imagingstarlight.ca (ASI 1600 cmos) for their help with this setup. In Canada, it is not easy to get all the adapters/components.
I am looking forward to trying the new equipment. Last night the temperature was -37C.
Anxious to get going, but at -37C, wires can snap without warning. I did that last year, so wait and wait. Clouds more clouds, cold and more clouds.
