GEM28 – Latest Update Part III

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 […]

NGC 225 Sailboat Cluster

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 […]

GEM28 – Latest Update Part II

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 […]

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 […]

GEM28 – Latest Update Part I

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 […]

Sh2-132 Lion Nebula

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:

M33 Triangulum Galaxy

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 […]

IC1848 Soul Nebula

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

iOptron GEM28 GoTo

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 […]

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
