I recently bought a QHY5-II-M camera since I am currently facing USB connectivity problems with my current DMK31 from “The Image Source” on my new notebook (update: I was unfortunately not able to get it working).
I tested the new QHY5-II-M camera on Jupiter with my 8″ GSO f/5 (f=1000mm) Newtonian telescope. I took some footage without and with a 2x barlow lens.
Moon through 8″ GSO f/5 (f=1000mm) with QHY5-II-M camera (without and with 2x barlow lens). Camera chip pixel size 3.75um x 3.75um, resolution 1280×960. I captured another video of Jupiter with the QHY5-II-M camera here.
Clear skies!

Around new moon in September 2014 I visited Appartamenti Agrituristici Agribaldo (https://www.agribaldo.it) close to Lake Garda for a few days and nights.
They offer an apartment with kitchen, bath, bedroom, garden and a wide free area around the building for up to 4 persons for a fair price. But the most important thing is that is is pretty dark there. The good thing is that is is not far away from Lake Garda and depending on the weather you can decide if you want to spend your holiday at night watching the sky – or – at day with e.g. hiking, cycling or climbing.

Actually this motif – the Great Orion Nebula (M42) – was one of the first nebula I have ever tried since starting with astrophotography. I was already quite satisfied with the first result (maybe because I didn’t know better :)). Tonight I decided to give it another try. Personally I think it is much better than the last one. The image is also available in full resolution.
