My Tak FSQ has been out of commission for months now. The Robofocus was not up to the task - due in part to clumsy installation on my part I'm sure. So I've been waiting patiently for a Bellepheron to arrive - should be here any month now...
I saw a post somewhere here suggesting that a dew heater will reduce the shift in focus over a session. Determined to get some imaging done, I bought one this afternoon.
After manually focussing, I've started on the Cat's Paw - looking at CCDIP the focus has been remarkably stable - with no need to refocus.
Brilliant!
Whoever it was who suggested this - many thanks
