Cygnus Wall

650mm focal length is already to much for the whole North America Nebula, so I tried to capture the most interesting area of the North America Nebula. At least most interesting to me 😉 Details

NGC 7380 Wizard Nebula

Finally clear sky! The Wizard Nebula now with 650mm focal length.What a difference to my previous shots of the Wizard Nebula at 400mm 🙂  Details

DWB 111 Propeller Nebula

The nebula season is coming 🙂 I think I now know how to prevent reflections: if there are no bright stars near to the field of view. Like in this one. Another solution would be probably to darken the inner tube and the spider. Details

NGC 6946 Fireworks Galaxy

Almost exactly one year ago my first image after a 3 years break was the Fireworks Galaxy. Back then I was still using my Canon EF 400mm f/5.6 lens. Yesterday I captured the Fireworks Galaxy again, but this time with my new Sky-Watcher Explorer 130PDS at 650mm focal length. I really like the additional focal […]

M 57 Ring Nebula (1mm T2 Ring)

This time I used the 1mm distance ring to fine adjust the distance between sensor and corrector. 1mm seems to be too much distance between DSLR sensor and coma corrector… the borders are worser than with the 0.5mm ring. And still not enough focal length for M 57 Ring Nebula, one of my favorite objects… […]

M 13 Cluster (0.5mm T2 Ring)

For this test I used a T-2 fine adjustment ring (0.5mm) to slightly extend the distance between DSLR sensor and corrector (54mm measured distance without any ring). The stars in the corners look much better than before, but I need to go to 55mm distance. Next time I’ll use the 1mm ring! Additional I encountered […]

NGC 6543 Cat’s Eye Nebula

This time especially the right upper corner is problematic (left upper corner too, but not that much as the right upper corner). At least not all 4 corners are affected in the same way… I’m unsure what’s the reason for this… So far, after reading a lot about the topic, I think the problem is: working […]

M 92 Cluster

So, this is a bad example of an astro image 🙁My DSLR almost slipped out of the focuser during handling on it. Fortunately I holded my 70D in both of my hands as it began to move… a very bad feeling 😉 Maybe I lost the collimation during that action or it was tilted in […]

M 13 Hercules Cluster

Even when there was a full moon, I had to check the performance of the primary mirror ring installation. It seems to avoid the bloating of the stars very well now! But I’m not sure if there is to much tension on the primary mirror…. especially the stars in the left corners seems to have […]

M 101 – First Light 130PDS

My first image with my new Sky-Watcher Explorer 130PDS telescope 🙂 It was a bit cloudy… 30 unusable subs. Out of 86! But it was worth it, even if the weather was not perfect and the moon already had 64%… But the over-all performance of my GEM28 among with the higher payload is really good! […]
