Today I used a break in the clouds to test how the astro-modified Nikon D7000 works with a h-alpha Filter. As the weather was very unstable, I didn’t set up the laptop for guiding, so some images were unusable due to trailing and passing clouds and full cloud cover at the end of the exposure resulted in oly 83x30s unguided exposures. Which way too short, but I am happy with the result under these circumstances.
NGC1499, Baader Planetarium, 1,25″ h-alpha Filter, 83x30s (41,5m) exposure, Astro-Professional 80mm f/7 refractor.
Two Nights, Two Scopes, Two Targets
In the first night I used my 80mm f/7 ED Apo for unguided 30s sub-exposures, in the second night, the 127mm f/8 Apo with 120s guided exposures…

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

Monster Sunspot AR2192
Today I had the opportunity to see and photograph the giant sunspot Active Region 2192, it already has rotated a bit away from our direction, so the probability of a massive solar storm with possible damage to space and other infrastructure is reduced.
Detail of the image above:
The images were taken with a Nikon D7000 camera using a Astro-Professional ED80 f/7 doublet refractor. A Baader solar filter ND3.8 was used for filtering the sunlight.
