6: Ultra thin M48 adapter

I ordered the Ultra Thin M48 to EOS adapter. A couple of days ago I got it delivered, it looks to be well built and fit correctly.

With this adapter I save 10 mm in length, maybe that will be enough. This adapter is much more stable compared to the old one, it dose not have a cone with its three stop screws that caused me problem, it wasn't possible to tighten enough. With this adapter I can't rotate the camera, but I can do that at another joint. This evening started with a clear sky, but after setup of the telescope and started all the programs the clouds came in. Sorry no test this evening.
