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 😉
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.
Mars in very good seeing, but only Red light, on August 14, 2020:
Saturn on August 13, in poor seeing:
Mars on August 18, in good seeing conditions:
A short RGB animation showing the rotation of Mars in one hour on August 18, 2020:
Mars on August 20, 2020, in mostly poor seeing. Syrtis Major feature is seen. Note the polar cap has shrinked a lot.
Jupiter with an outbreak, on August 21 2020:
And an animation spanning about 20 minutes showing the rotation of the planet and the outbreak:
Saturn on August 21, 2020:
Mars on August 21, 2020:
And an animation of Mars rotation, acquired in 2 hours and 45 minutes:
A selection of three de-rotated views of Mars from August 21-22, 2020:
The three planets of August 21, 2020, not to scale (Mars should be almost two times smaller):
A test for my new Baader Johnson U filter. Horrible conditions, Venus being only a blurred object on the laptop screen:
Mars with an orographic cloud in very good seeing:
A short animation showing 1.5 hours of Martian rotation on August 29:
Mars in fantastic seeing on September 1, 2020:
The RGB series from September 1, showing some clouds on the terminator in the blue filter image:
An animation from Sept 1 from the Red filter data:
An animation from Sept 1 from the Blue filter data:
An animation from Sept 1 from the Green filter data:
RGB all filters animation:
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.
A short animation showing 12 minutes of rotation”
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…
Planets of September:
Mars on September 13, 2020, in fair seeing:
Mars animation showing the planet rotate in about 1.5 hours, on September 15, 2020. Red filter data acquired in very good seeing.
Mars RGB set from September 15, 2020:
RGB animation made up from four sequences:
And the sequence from the above animation:
Jupiter on September 16, under poor seeing conditions:
Solar imagery from September 24, 2020. 150mm achromat, Quark H alpha filter, ASI174MM.
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 😉
