Persei Cluster, again…

Yesterday I started only MGEN recordings to test the new parallel setup but ended up on the Persei Cluster 😉 I love this double cluster… Unfortunately 44 of 125 subs were unusable due to the persistent DEC problems on my GEM28… on some other were clouds, so in the end I could integrate only 67 […]

Star Cluster Group

Full Moon time = star cluster time! This group of cluster were very well in sight. NGC654, NGC659, NGC663, M103, and IC166. Everywhere star clusters 😉 There is a small cluster in the right middle area wich was not plate solved and also not listed in Stellarium… maybe someone knows? Details

Bubble Nebula Wide Field

Again testing the gear mesh adjustment… and I’m still not done 🙁 So far I adjusted the gear meshing 4 times in the range of 1/8 turn counter clockwise and 1/8 turn clockwise, since the manual says not more than 1/4 turn in total. I contacted iOptron again regarding this issue and they told me […]

Persei Cluster

The next few days looks promising regarding weather, so I can continue with my gear mesh tests. I begin to record every session with the MGEN since it’s very valuable for finding reasons for tracking errors. I’m still using NGC7789 as test target, simply to have similar data to compare. At midnight I switched to […]

Caroline’s Rose Cluster

Since it’s almost Full Moon I decided to capture a star cluster to continue testing my new mount. This time with 90 seconds exposure time, like on the Star Adventurer. A slight DEC error was present on 4 of 48 subs… The interesting fact is that the error appears in a 10 minute interval = […]

Bubble Nebula Wide Field

Since days very good weather conditions. It’s a complete different thing to photograph with a modified DSLR compared to last years image. 2021 reprocessed with slightly different/new processing steps. 2x drizzled, scaled down to original resolution. The old version is still available on AstroBin. Details

M 45 Pleiades

Since weeks bad weather… but yesterday I had luck 🙂 So, again M45 Pleiades (how wonderful to focus with the Bahtinov mask because of the bright stars…), this time at f/5.6. Therefore no spikes. It looks more realistic to me with the round stars and no spikes… Drizzled 2x and resampled to original resolution. Details
