M16 – The Eagle nebula
M16 has become famous with the famous image of the Hubble telescope showing the pillars of creation. They are also visible in the center of the image below.
This was a first, quick test with the 0,75x reducer (27TVPH) – but I think focus was not good, so my judgement about the quality of the image the focuser delivers is not final yet.Read More
NGC4565 – a springtime favourite
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.

Venus with 200mm reflector
Without an UV or deep violet filter, the Venusian atmosphere appears very bland, but the phase is very prominent in this image.

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.Read More
