The following series was part of a test for the 228mm H-alpha refractor. Only the red part of the spectrum is usable (as it should) so only monochrome images have resulted. All three imaged planets were at around 20 to 23 degrees above the horizon, so pretty low for any serious images; still, some details are detectable, like the GRS, the Cassini division, the polar cap.



While testing some filters (both H alpha and others), I’ve also acquired a few views of today’s solar features. A few spots, a few proms, and some other details observable in the chromosphere. All shot with the 150mm achromat and Quark filter.


And a prominance:


3. The planets with the 355mm Newtonian on August 3, 2020. Under moderate to good seeing. Mars is getting bigger πŸ˜‰

An animation spanning almost half an hour:


The Sun in H-alpha on August 12, with a lot of details. Of importance is a complex-looking prominence, but also a new active region. 150mm refractor, Quark Chromosphere, ASI 174MM. Seeing 5-7/10.

Moon shots with the 355mm Newtonian in some good seeing on the morning of August 14, in red light:





A short 8 frame animation showing about 80 minutes of rotation on planet Mars. August 14, 355mm Newton, Red filter. Seeing 7-8/10. Poor transparency.

A test for my new Baader Johnson U filter. Horrible conditions, Venus being only a blurred object on the laptop screen:

One more animation showing the IR channel for 1.5 hours:

The Moon on September 1:

Mars on September 4, 2020, in very poor seeing. Note the elongated cloud in the blue filter image, near Arsia Mons.

Mars on September 7. This is the first sequence of the session, when the seeing was not that good. Just moments later the seeing improved considerably. More data will be processed soon.

Another series from Sept 7:

And a two frame animation:

Some lunar imagery from September 8:

Mars on September 9, 2020, from high up in the mountains, near Piatra Arsa Peak. Some very good to excellent moments of seeing, but mostly fair to good.

Saturn on September 13, 2020:

An animation showing planet Jupiter rotating in half an hour. Note the chaos in the bands made by one of the currently three disturbances:

Jupiter images from September 13, 2020, showing the first NTB disturbance effects on the NEB. Poor seeing in the RGB data, so I had to mix it with the IR. The low altitude of the planet is not helping me much…

Mars on September 13, 2020, in fair seeing:

Mars on September 23, 2020 with a 150 mm achromat refractor (Bresser). Just my first light with the ASI290MM camera. It was a fun session πŸ˜‰
