Planet Images

Here is Jupiter captured with a de-forked Celestron C90 Astro, taken using the stock 2.5x barlow extender and an ASI-224MC camera.

I bought a Celstron Evolution 8 for visual observation, but I couldn’t resist trying it out for imaging as Jupiter came to opposition in September 2022.

The other blue planet, Uranus, proved a tough target when i pointed by Skymax 127 towards it in February 2021.

These are some images I’ve taken with my 127 and C90, back to back on the same night with the same kit (HEQ5 Pro, 2x barlow, ZWO ADC and ASI-120MC). Each time I’ve taken the best 25% of 10000 frames using AutoStakkert, and then performed wavelet sharpening in Registax.

Previously I made the following comparison between 127 and 102.

A week past opposition and finally Mars is in reach, albeit briefly before it is obscured by a house!

Jupiter on 28th June 18, getting lower in the southern sky after sunset. Good seeing for once allowed use of a 3x barlow. Happy with the result!

Another image of the Callisto transit. I find myself revisiting the wavelets page on Registax, endlessly moving the sliders… am I the only one? [caption id="attachment_1264" align="aligncenter" width="513"]SkyMax Jupiter May 2016_20160523_2137_21_wave_crop Transit of the moon Callisto across the northern polar region of Jupiter, taken on May23rd 2016 using an SPC900NC webcam, a Skywatcher Skymax 150 Pro telescope and a 3x barlow. To focus I used a Bahtinov mask on Arcturus and locked the focuser.
SkyMax Jupiter May 2016_20160523_2102_55_wave3
Jupiter on 23rd May 2016. There was a brief period of what looked like excellent seeing, where more details became visible on the disc for a few seconds at a time. This image was produced from Registax based on 300 frames of data captured at 10fps. The moons to the left and right are Ganymede and Io.

Jupiter on 12th May 2016. First light through my new Skywatcher Skymax 150 Pro maksutov. I didn’t use a barlow so this is a shot taken at F12. 40s at 30fps then PIPP and Registax. Now where is that barlow…

Jupiter and Venus in the western sky, at 10:15pm local time. The exposure was 1/100th of a second.
Jupiter and Venus in the western sky, taken at 10:15pm local time on June 30th, as the duo skulked off towards the horizon. The exposure was 1/100th of a second. I had hoped for a perfect, miniature Jupiter image but the brightness of the two planets was so different that it proved tricky to achieve. ‘Happy with the crescent of Venus though, which is now clearly different from earlier in the year.

Saturn in June 15
Saturn in June 15 taken with 1000 frames at 1/25s using the C90. The ringed planet was low above the southern horizon: 15 degrees at most. The thing I always forget is that Saturn is much fainter than Jupiter and it shows in the final image.
Venus in May 15 taken with a C90
Venus in May 15. I think we’ve reached the heady heights of 5 out of 10! These 500 frames were captured just as the sun set. The sky was still bright and blue and perhaps this reduced the contrast enough to capture a cleaner shot. An exposure of 1/250s was used, with the only real tweak being to the RGB align in Registax, to remove the blue fringing. The original video is Video of Venus with C90.
Venus in May 15 taken with a C90
Venus taken in the minutes after sunset, with a 750 frame capture. The exposure was set to 1/100s. There is some obvious colour fringing going on – perhaps this is an artifact of the Mak’s corrector plate? As a planetary picture I would have to give it 2 out of 10, but at least it added to the list of objects my family have been forced to look at!
This time I took 2000 frames, and let RegiStax select the best 60%. The seeing was better than with my first attempt, and more detail is evident.
Jupiter and Io and Europa
If you look closely you can see the moons of Io and Europa to the left of the planet. For this shot RegiStax took the best 700 frames from a 1000 frame file, with the exposure set at 1/25s.
Jupiter with a C90 Mak
This is the result of my first attempt using a Celestron C90 Mak and a 3x Barlow. I captured 1000 frames at 1/25s, and Registax took the best 800 or so. The C90 should give me the greater image scale I need, but it certainly doesn’t focus as well as a refractor. The seeing was only average so I will try again, this time grabbing 2000 frames.

Mars in 2014.
Mars in 2014. By the time my 3x Barlow was online the red planet had shrunk. The image scale is too small, as my set-up is running at about F18, whereas the forums all tell you to try for F30. Short of buying a longer focal length scope, the only option would be to use a camera with smaller pixels.
Saturn in 2014.
Saturn in 2014. It looked great live on my laptop’s screen, with the Cassini division evident. Something is lost in the final image. I would have to class Saturn as a work in progress!
