The planet Mars captured with my Celestron C925 SCT telescope and my ASI224MC colour camera. I used a Powermate x2 barlow lens to give a higher image scale together with an Atmospheric Dispersion Corrector (ADC). A total of 12000 frames were captured using Firecapture to a SSD drive on my capture PC. I used Autostakkert to process the best 20% and then PixInsight to bring out the details with 8 wavelet layers. A bit of unsharp mask afterwards to sharpen it up a bit. Mars was to the East of the meridian and about 40 degrees in altitude. From my backyard in Nottingham, UK. I am quite new to using the ADC and what I did was use the colour alignment tool in Firecapture to “tune” the ADC to get the colours all as perfectly aligned as I could.

Jupiter, 7th December 2022 with C925 SCT and ASI 224MC camera I am not experienced with imaging the planets other than the Moon. This image is not going to win any prizes or keep the award winning planetary imagers awake at night! However, it’s a first effort at Jupiter and a foray in planetary imaging to give me some other astronomy options since almost always, when it is clear the moon is bright thus rendering deep sky observing and photography impossible I used my Celestron C925 telescope with a x2 Powermate (a 2″ version). I then used an ADC to try and improve colour correction and to this was connected my ASI224MC colour camera. I tried my very best to “eyeball” the focus the best I could. This is very difficult to do as Jupiter was bouncing around considerably due to quite poor seeing. Jupiter was at about 30 degrees…

A selection of images I took with my C925 and ASI224MC.  Transparency was reasonably good but seeing was quite poor and the image was wobbly.  Each image is developed from a 5000 frame .ser file choosing the best 15% of frames as a result of the poor seeing.  The Moon is at a phase of 82% waxing gibbous and some nice shadows on the terminator. From my back yard observatory in Nottingham, UK.  Using Celestron C925 SCT telescope and ASI224MC colour high speed planetary camera.Telescope is at its native focal length of F10 for all these images since the seeing was much too unstable to use a Powermate or Barlow, even a x2 one woudl have been too much on this session.
