Small Mars, 9 Jan

Recommended Posts

Here is an image of Mars I made on 9 Jan this year, with a C8 SE, and ASI120MC camera.  The images are rather small (around 7" dia).  Mars is now much higher in the sky than at opposition, so it seemed worth taking a few farewell images as it diminishes in size. Captured with Sharpcap.

I did not use the ADC - the images are corrected for AD in the processing in Registax.  This is from a run of 3000 images.  I have included a x3 Photoshop zoom of the same image to indicate the size of Mars at opposition on the same scale.  I was quite pleased to record some surface detail, corresponding with the position of Syrtis Major.  If I'd had more time, I could have tried some images using a Barlow lens. I have just discovered that I can unscrew the lens section from a Skywatcher x2 Barlow and screw it onto the 1.25" nosepiece of the ASI120MC, which will give a more modest zoom (I think).

Yes, Mars is nice and high now, unfortunately really small also, nice shots!

Definitely some albedo detail showing in the smaller images.

As far as post processing out AD; Damian Peach says in his article that although you can improve the effects of AD in post processing it does not remove everything that a good ADC will remove at the time of imaging - if correctly set up.

Nice images with some fine detail. I am woefully short on planetary imaging and will make a serious attempt this year.

      Yesterday I managed to climb out of bed at a little past 3:30AM to get my small portable rig out to a small nearby park and setup to observe Jupiter, Saturn and Mars. I got the Skywatcher Evostar 72ED DS-Pro last summer so I was especially excited to see how it would perform on Mars because of its red wavelengths which many small fracs often have trouble with handling.
      At first it was partly cloudy but I persisted and was out and setup on the field at around 4AM. The sky was already surprisingly bright here in Denmark but Jupiter was shining bright and Saturn faintly visible almost right besides Jupiter. Fortunately for me it wasn't too cold, but I was happy I brought some gloves anyways;)

      This picture was taken at 5AM while I was observing Mars.
      I remember from last year that my scope didn't perform great on Jupiter for some reason, and the view of the gas giant wasn't anything different this time either. Using my 4.7mm ES 82 degree eyepiece not much detail visible except the two main bands and its moons. I would later return to Jupiter after the scope had cooled down a little and the view was perhaps a little sharper.
      Pointing the scope at Saturn, which I was very satisfied with last year, I was amazed of the detail the small scope managed to squeeze out. It doesn't compare to the view I had last year with my 10" dob under great conditions at 255X but I was able to easily spot surface banding on the planet itself, and the Cassini division was also surprisingly stable. I really enjoy the stable and consistent view through the small refractor! I observed Saturn for quite a while until I eventually set out to try to find Mars. At this point I couldn't even see Saturn with the naked eye but I was fortunate that Saturn and Mars were approximately the same elevation above the horizon.
      After a few sweeps across where I though Mars would be I finally located the small red speckle, this time with my 6.7mm eyepiece so I had a larger FOV. Switching to the 4.7mm, though still very small, I was surprised that I could pick up a dark surface marking across the disk on the lower southern half of the disk. Furthermore, the southern polar cap was really pronounced and you couldn't miss it. I watched Mars drift through the FOV until about 30 minutes after sunrise where the contrast between the planet and the sky became too low and the dew started to set on the lens element.
      Using my small refractor for observing the planets I have always wanted to magnify things a little bit more, and I think the telescope would have no problem doing so. A Nagler zoom 3-6mm has been on my wish-list for a couple of years now, but the upcoming planet season really makes me want to find one second hand
      Here's a video I've made that covers what I've written above with some footage I tried capturing through the eyepiece:
      I hope everyone on here is still doing well despite the current situation!
      Clear skies!

      This is a re-processed image from some videos I recorded on a trip to Somerset in 2018 during the Mars Opposition. Unfortunately, I lost the exact day of the recording. Telescope: Skymax 150 Maksutov with a TeleVue 2x Barlow. Focal length was approximately 3600mm. Camera: Canon 550D unmodified at ISO 200 with 1/60 exposure. Video was recorded in 640x480 crop mode at 60fps. Processing: Video formatting, quality control and centralising done using Pipp, stacking and tweaking done using Registax.

      This planetary grouping from 20th March around 5.30am shows Saturn to the left with conjunction of Jupiter above & Mars below, sharp eyed may also see...  Io, Ganymede & Callisto in a string just right of Jupiter.
      Image taken from Lesmahagow, South Lanarkshire looking toward the SE.

      Celestron C8 XLT + extras and SkyWatcher Star Travel 80 (ST80)
      I have a Celestron C8 with XLT Starbrite coatings. Will include the full length base plate, both visual and imaging backs, scope rings, front 8" end cap and the finder scope with it. No box I'm afraid. Optics are good and clean, focal length is huge - 2300mm from memory. This lot would cost close to £1300 new and one with less spec went for £750 on fleabay recently. Might be interested in a part exchange or will let it go for £450 collection only.
      Also, I have a SkyWatcher Star Traveler 80 - good optics, used as a guide scope - just the scope itself (does not include the barlow in the photo) - now including dovetail bar and scope rings looking at around £50 for it.
      I have decided to save up for another refractor, WO, Equinox or even toward an Esprit. However, I would also consider p/ex for an Intel NUC and/or Pegasus Astro Pocket Powerbox.
      Please excuse some of the colours - I used my astro modded 6D which was in the observatory so the "nice" purple is actually black !!
      Both these are collection only.

      Hello everyone, 
      I'd say it's been about 6 years since I last posted on this forum, oops 😁. 
      Anyway Ive been looking for a new scope something with abit more punch than the skywatcher 130m I have been using and came across this beaut on eBay, I won the auction and picked it up yesterday. The guy was selling it on behalf of an elderly gentleman man who couldn't use it anymore, (it's been sitting in an unheated garage for many years 😩) he had no idea on the make or model other than its a c8, I did a bit of research and found its a c8 super polaris. 
      The mount has both RA and Dec axis motors but I have no way to power them, the action of the mount is buttery smooth. However I plan to mount this on my HEQ5 anyway... 
      The scope its self seems to be in good condition some minor scratches on the tube but nothing too alarming, no finderscope or dust cover but I plan on adding my own finder anyway. The focus is super smoothe and can't see much if any image shift in use (not tested on a star yet due to preverbial clouds) 
      My main concern is as its been in an unheated garage for some considerable time and there seems to be some minor mildew on the primary which I plan on cleaning... when I feel brave enough.. 
      I don't think the secondary screws are original, should be Phillips head? Tested on a small light down the garden and it seems to be well collimated, but does have a small amount of mildew on it
      I don't recognise the mounting bar, I would like to swap it to a vixen style bar so I can mount it on my HEQ5 maybe this?
      Anyway that's where I am with it sorry its been so long since I last posted, I hope to be a tad more active on here. 
      Harry
