Taken through my Meade ETX-90 telescope. I like the tiny craters in the seas, such as the 6.6 km Deseilligny crater just to the left of 16 km Bessel crater in the Mare Serenitatis, and the ones just inside the dark part of the Moon.

A nearly full moon on April 28th. Single exposure taken through a Meade ETX-90 telescope in Oslo, in the backyard. Notice the color shades, telling which areas are rich in titanium (blueish) and iron (reddish).

Comet C2020 F3 Neowise, in a stunning capture from last night. Not only did I capture more of the ion tail in this capture, I actually saw it, as well. While I was capturing the data to compile this half-hour composite exposure, I had set up our recently acquired Meade ETX-90 and sat in awe at the view through the Televue 24mm eyepiece. The nucleus has gone from bright yellowish-orange to a greenish hue as well as the coma immediately surrounding it. This was unaided, strictly using a Nikon DSLR.

Raw footage.Captured with a Canon 750d stuck in a Meade ETX-90 OTA mounted on a Skywatcher EQ3-Pro using manual movie mode at Full HD @ 25 fps, 1/125s exposures and ISO 12800. I should have used a faster exposure, maybe 1/400s, to avoid the blurring of the ISS (next time). This image was created by stacking every other frame of the transit over another image of the complete crescent Moon that I took after the transit, and then flipping the composite to remove the effect of the telescope's mirror.

New-cycle sunspot AR2765 (in the lower left quadrant), the first sunspot of new solar cycle 25 is the first to appear after a 122 stretch of spotless days. It is active with relatively weak (B-Class) solar flares. Afocal exposure using a Samsung Galaxy 6 smartphone camera through a Meade ETX-90 Maksutov-Cassegrain 1250mm focal length f/13.8 telescope with a Meade 25mm Series 3000 Plossl eyepiece.

I like the tiny craters in the seas, such as the 6.6 km Deseilligny crater just to the left of 16 km Bessel crater in the Mare Serenitatis, and the ones just inside the dark part of the Moon. I shared the direct live view through the telescope with dozens of people at Mt Lofty Summit. EVERYBODY said "oh, wow", which is exactly what I wanted to hear.
