Go to GEM28 – Latest Update Part IV Luckily I was able to continue my tests… finally clear sky for at least a week. I started with a serie of guided 10 minutes exposures. Guide speed this time 0.25x for DEC (before: 0.90x). Adjusted gear mesh for this test: RA -1/2 turn, DEC -3/4 turn […]
Even if it’s still almost full moon, I used the last clear night (at least for a week) to test new settings (GEM28 and MGEN). When I was done with the tests, I did a little star cluster session 🙂 I got better results than before with only 2 different settings than before: I tightened […]
Go to GEM28 – Latest Update Part III Update Sept. 25, 2021 After analysis of the guided material, at least one positive thing resulted: I never reached that good eccentricity values before. This is very sursprising because the MGEN values doesn’t look very well, once again… The best sub exposures are IMG_1453 and IMG_1455, since […]
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 […]
Go to GEM28 – Latest Update Part II UPDATE Sept. 22, 2021 It’s really an adventure with my GEM28. Differential Flexure is likely not responsible for my guiding errors, but at least I learned something new 🙂 The Differential Flexure hint was given on this German forum thread:https://forum.astronomie.de/threads/staradventurer-2i-vs-eq5pro-vs-eqm35-vs-ioptron-gem28.312432/post-1610995 2 months ago I started this thread […]
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 😉 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
