UPDATE Sept. 14, 2021: It seems my DEC problems are caused by Differential Flexure. The guide scope or lens are drifting during the session relative to each other (in a range that is mostly not noticeable by eye). The reason can be various: pulling cables, insufficient attachment of components… So I’ve ordered rings also for […]
The Lion Nebula is much more faint than I thought. So I spent the last 2 nights for it. It’s a very star rich region. More than 4 hours integration. Each session is calibrated for it’s own, then registered and integrated all at once. Details Shooting impression:
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
I’ve used the GoTo system of the iOptron GEM28 for a few weeks now and I’m really impressed about the accuracy 🙂 The traditional 2 or 3 star alignment is ok, but the real precision comes from the Sync. to Target function. It enhances significant the GoTo accuracy. Enhance GoTo accuracy Before I start the […]
Full Moon time = star cluster time! This group of cluster were very well in sight. NGC654, NGC659, NGC663, M103, and IC166. Everywhere star clusters 😉 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
Yesterday afternoon I aligned the polar scope reticle in vertical and horizontal direction towards a distant buidling because the night before I suspected that it’s not aligned well anymore. I was right! I’m not sure if this is my mistake. Before that all started, I transported the mount with attached counter weights from my balcony […]
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 […]
