Description

A retry of M101 using the EdgeHD on its f/10 configuration. The result is, especially on f/10 on par with the two nights were guiding was good (below 1 RMS) and a bit above (not so good). As an experiment I created longer subs to see if the movements would cancel out some of the effects. APP picked some of those longer exposure for the final stack.

In all its a mixture of a few 30 min and 5 minute subs during nights with and without gusts of wind. Nethertheless I am happy we had at least some cool nights to create pictures with, also almost no moonlight interferences... Good nights to experiment with guiding and the CEM120 mount.

During one of the nights the Moonlite CRL did not respond on the Pegasus focuser so as an alternative I had to switch focusing with the Bahtinov (manual) focusing method.
