Finally cooler and longer nights 🙂 But the session started with a non-responding GEM28 after starting the guiding calibration… so annoying!At least the rest of the night was problem-free… Details
I think the CLS-CCD does a good job for the Heart Nebula. Especially from my light polluted home. Details
My DSLR doesn’t like these temperatures… Had to fight with background noise structures. Looking forward for the colder nights 😉 Details
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
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
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
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… […]
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 […]
Three sessions in a row without a freeze on my GEM28. Yeah! But I expect the next very soon… Details
Yesterday I took the chance to shot the Fly- and Spider Nebula and some cluster neighbors, but had to stop after 1.5 hours due to clouds (in contrary to the weather forecast). Additional I had a forced 15 minutes break: my GEM28 had again a crash/freeze. I had to reset everything: back to zero position […]
