Jupiter 2017-05-09
Software used: Autostakkert 3.0, Registax, Fitswork. This version is a bit softer, shows much less artifacts but still more detail I think.

Venus at 4%
Today Venus was a very delicate crescent, with only about 4% of it’s visible disc illuminated by the sun. I used the 127mm f/8 refractor with a 1.4x teleconverter and took a number of images using the Nikon D750. 20% of 46 individual images were used to create this image using the software Autostakkert:

Testing a new guiding setup
This evening I did a quick test under the stars to see, how iAstroHub 3.0 works with my setup.
Apparently it works quite well, though I need to test with longer exposures.
The sun 2017-01-28
The sun shows only few spots when near solar minimum. Today the Spots AR2629 and 2628 were clearly visible.
