Jupiter, Io Transit
Clavius and Copernicus
Crater Copernicus, 200mm GSO Newton f/5, QH5IIc camera, Televue 3x Barlow lens.
Lunar telescope comparison 80mm, 127mm, 200mm
Last night I photographed the same lunar regions through 3 different telescopes:
- Astro-Professional 80mm ED f/7
- Astro-Physics 127mm f/8 refractor
- GSO 200mm f/5 Newtonian
Clavius, Vallis Alpes, etc.. and Venus!
Today I pointed the 20cm Newtonian telescope again towards the moon. Shortly after first quarter quite a few nice landscapes are visible.
All images were captured as 120s AVI files using a 3x Barlow lens and the QHY5IIc camera.
Crater Clavius
5 day old moon
The 20cm Newtonian telescope in combination with the Televue 3x Barlow show a wealth of detail on the moon.
4 day old moon
I haven’t photographed the moon at this age, so here are some new lunar features for me. Read More
ISS solar transit
As the ISS orbits our planet, from time to time it passes in front of the sun for a given location.
https://www.calsky.com and https://transit-finder.com/ allow you to predict such transits for your location.
Last Saturday such a transit happened, and I was able to capture it:

Spring is here: Galaxies and Clusters
Springtime is galaxy time! After a frustrating friday night with incorrect mount setup, iAstroHub not working properly, which resulted in badly focussed and guided images, saturday evening proved much more successful:
Leo Triplet, M65, M65 and NGC3628, 25x120s, Astro-Physics 127mm f/8, Nikon D750, BackyardNikon, PHD2, Regim, Photoshop, Lightroom
The Leo triplet is a trio of galaxies which are physically near each other, a faint tidal tail can be seen to the upper left of M66, the lower right galaxy.
The distance to this galaxy group is about 35 million lightyears.
