That wasn’t funny at all… after 17 lights suddenly I noticed a huge drift in DEC, M33 were not centered anymore. But a correction was not possible, I was able to navigate within the menu on the hand controller, but no reaction on commands… even back to zero position was not possible… 🙁Only after a […]
Finally again clear skies 🙂 This time only 4 out of 79 lights were unusable due to slight DEC trails… still searching for the ideal MGEN settings. Details
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
After my polar scope disaster and recovery I captured NGC 7822 last night to check if everything works fine again. It was a very warm night. More than 20°C even at the end of the session… Drizzled 2x and resized to original resolution. Details
Still not happy with DEC performance, but at least I can setup the mount in the darkness without light now 🙂 This image contains only 75% of the lights… On the other 25% there are clouds or DEC error 🙁 Details
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 […]
I still looking for the ideal adjustment for gear meshing… this time around 15% useless subs. The other subs resulted in this image: Details
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 […]
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 = […]
Next first light with the iOptron GEM28. OK, the coming moon is annoying, but so far I’m really happy with the result. Even 6 minute subs were no problem at all. Since my apartement’s lights were fully illuminated, to be able to read my notes and statistics, there is a faint reflection in the right […]
