I find edge-on galaxies especially pleasing, I guess this is the reason while I return to NGC4565 so often.
While the images were captured, the Starlink satellites which launched yesterday passed almost through the Zenith. They were still very closely grouped, and changed dramatically in brightness when the culminated almost in the Zenith. Here are some images of that pass:
Soon after reaching their highest point in the sky, they entered Earth’s shadow and became unobservable.
Without an UV or deep violet filter, the Venusian atmosphere appears very bland, but the phase is very prominent in this image.
Galaxies in Leo, M 65, M 66, NGC 3628, NGC 3893 among many others in the backgroud. Astro-Professional 80mm ED f/7 with 0.8x reducer, 53x120s (1h46m), ISO 400, Nikon Z6 – definitely not enough focal length for this subject
Comet Atlas C/2019 Y4 makes a rather sad appearance in this wind-shaken exposure.
Read MoreComet C/2019 Y4 (ATLAS) will maybe become a naked eye comet in April, and could probably become reasonable bright as comets to, now it is a faint smudge in the constellation Ursa Major. NikonZ6, cropped, 85mm lens, 62x15s at f/2.8, ISO 3200
A late friend of mine owned a Zeiss AS 63mm lens, it took me a while to figure out all the details, as it is not mounted in the original cell, but in a custom machined one, and the tube loooks like it is self-built too.
In the process of establishing the quality of the lens I took these images with a QHY5L-IIc camera in prime focus configuration. As the conditions were very changeable because of passing clouds, the brightness of the images had to be adjusted individually, color saturation has been enhanced.
