A 78 night period of Saturn and its moons
For this composite picture, I used ZWO asi290mm mini Camera, ZWO L-filter, a SkyWatcher 90mm Maksutov-Cassegrain Telescope, and a tripod for monocolor pictures and a ZWO asi224mc Camera and ZWO IR-UV cut filter for the colors of Saturn and Titan.
This picture was made through a journey of 78 nights. I was able to see how Saturn moons rotate around it through this period. Iapetus is the moon with the widest orbit radius in the picture which almost disappears when it is on the left side of the planet from earth which my picture is able to show that as well. I started from June 15th 2021 and finished on August 31st 2021.
Main Sunspot in Active Region 2835
Date/Time Taken: July 1, 2021, 10:58 MYT (02:58 UT) Location: Heng Ee Observatory, Penang, Malaysia. Equipment: APM-TMB 228/2050 Telescope, Lunt Solar Wedge, Baader ND filter OD 3.0, Baader Solar Continuum 540nm, TeleVue 3x Barlow, QHY5L-II-M Camera Processing: Stacked with AutoStakkkert!3, Wavelet adjustment with Registax 6, Enhancement and false color with Photoshop 2020
This is the best sunspot image I have ever obtained at this magnification. After switching from 2x barlow to 3x barlow, I mistakenly judged that the seeing condition had deteriorated and thus did not proceed to capture a mosaic of the sunspot group. I regretted this decision as soon as I see the result after processing.
Crescents in the daylight sky

In the morning of 19 June 2020 a lunar occultation of our sister planet Venus was predicted. As usual, trying to frame this event was a nerve-racking endeavor. Thick clouds moved to and fro and every time I could catch a short glimpse of the thin crescent of Venus I pressed the release button. On the live-view image the moon itself was invisible, but when I inspected the frames on the computer back home I realized that my efforts were not in vain. The meeting of the two slender crescents may be the most aesthetic picture I ever took.
ISS transit while the partial solar eclipse 2021
Telescope: TMB LZOS 152/1200, Riccardi 0.75 M82 reducer Mount: Astro Physics 900 GTO Camera: ZWO ASI 183 MM PRO, Astronomik 2c green filter Software: Autostakkert! and Photoshop for the final composite.
On June 10th 2021, i took a 100km drive close to the center line of the ISS transit while the partial solar eclipse here in southern Germany. Clouds left and right, but at 12:51:29, the sun was in a spot of clear blue sky. So I was able to capture that 0.58s transit with 25fps, yielding the 14 ISS footprints in the image together with the silhouette of the moon.
