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 […]
Finally clear sky for the next few days… still small clouds but the conditions yesterday were good enough to test my new iOptron GEM28 mount. I know the dovetail solution with the EOS 70D, EF 400mm and guidescope side-by-side is not ideal regarding balance… Unfortunately I’ve no other possibility to attach my equipment right now. […]
After almost 2 weeks with the iOptron GEM28 I want to share my first impressions, even if I still were not able to test the mount in the field due to bad weather… So far, I found 2 issues: Saddle Locking Knob scratches on the DEC unit Polaris seems to be on a wrong position […]
Finally the sky was clear last night, so I captured once again the Wizard Nebula. With my last results I never was really happy. It is a difficult object for 400mm focal length… f/5.6, 2x drizzled and resized to original resolution. Details Cropped:
Again I’ve learned something new about the polar alignment 🙂 : Polaris can be at different positions in some apps that takes into account refraction correction! Wrong position of Polaris? The iOptron GEM28 mount has a polar finder section on the hand controller. But the position of Polaris seemed to be wrong, compared to the […]
6 years ago I started astrophotography with the SkyWatcher Star Adventurer and finally the next step on my journey is taken 🙂 My new mount is here! The iOptron GEM28. The mount head only weights 4.5 kg, but is capable to carry 12.7kg payload, for astrophotography 8-9kg should be optimal. And it’s still very portable. […]
First light for my new UV-IR block filter. I want use it instead of the CLS-CCD filter, mainly to gather light wavelengths that are blocked by the CLS-CCD filter. 2x drizzled, resized to original resolution, almost no color manipulations except of calibration. I’m really sursprised about the result. It looks more dynamic to my last […]
Once again I captured the Cygnus Loop during the last two fantastic nights 🙂 The first night I’d to fight with wind… half of the subs were unusable…Yesterday was perfect! No wind and absolutely clear sky… Unsure how much star size reduction… I chosed this “medium” version 😉 Details
Recently this YouTube video was posted in a forum thread on AstroBin where it’s suggested not to use dark frames for DSLR deep-sky astrophotography! Since this would be really a huge time saver, I took the last weeks data of my Propeller Nebula session to create different stacking combinations to find out, if there is […]
Unfortunately I never created flat frames in the past. It seemed laborious to me. White T-Shirt and so on… I didn’t realize that I was already equipped to make flat frames. My netbook with a non-reflecting display (Asus X205T). It’s really worth to take flat frames. It removes vignette and any particles on the lens, […]
