This is a quickie image taken of the moon this morning as I stepped outside to check on my gear. I had intended to cover everything up after moonrise, but the sky was so clear I decided to push ahead until dawn.

After taking a set of images of the crescent moon I decided to try and capture the beautiful Earthshine. The source images were gorgeous without a hint of color fringing. I had to remove a ghost image that indicates that the objective in this old Unitron does not have AR coatings. Processing also brought up a little bit of color fringing, but it is still very limited. Note the little star trail just above the moon that shows how far the moon moved during the time the source images were being taken.

This is quick test image taken with my 60 year old Unitron 155c on its second night out. During this test I found that the 155c was much easier to point and to fine tune the field than I had expected. I was particularly interested in whether I could make fine adjustments in the R.A. as this model lacks the secondary fine R.A. control meaning that you cannot make fine adjustments in R.A. while the clock drive is installed. This turned out not to be a problem. The field of view of the full frame EOS Ra is large enough that pointing the scope was relatively easy. To make fine adjustments in R.A. I simply pointed the scope slightly west of the target, and then turned the clock drive off, letting it drift to the center of the field, and then turning the clock drive back on. Easy peasy. The clock drive itself performed flawlessly off of the 120vac output from my lithium ion battery pack, though I need to work on the polar alignment to get the best performance from it. It is certainly plenty good enough for visual and if I get serious about imaging with this scope I should look at mounting it on my Atlas.

This is an excellent example of the high resolution performance of the Unitron 142. I was pleasantly surprised by the lack of color fringing with this relatively long f/ratio scope. Note the lunar terminator sweeping across the southern highlands, indicating that the moon is passing north of the Earth’s shadow.

This 50 year old Unitron produces a sharp, high contrast image with little or no chromic aberration. The 142 equatorial mount is very stable with excellent slow motion controls and a very accurate synchronous drive. I was curious to see how well it performs with basic imaging and this is the first test image. I chose to use my uncooled ASI294MC as is it a very lightweight color camera with a modest size chip and since there is no shutter there wasn’t a problem with vibrations. This does a fairly good job showing the excellent image quality and the lack of color fringing. Very nice!

This image was taken as part of in initial test using a Baader Mk III MPCC with this wide field 8” SCT and the original, uncooled version of the ASI 294MC. I’m configuring this for remote observing, but it is working so well that I’m going to conduct some additional tests to see how well it works for general purpose imaging.

This is a quick stack of images that I grabbed of the moon while setting up my gear for an evening of remote observing. This was taken with the original, uncooled version of the ASI 294MC which is a wonderfully simple, lightweight, and effective camera for this type of work.

The short streak in the center of this field shows the apparent motion of (1) Ceres over the period of about 30 minutes on the evening of November 22, 2021, at 10:00pm local time. Ceres was the first asteroid discovered as part of a methodical search for a ‘missing’ planet between the orbits of Mars and Jupiter that began in 1800. Giuseppe Piazzi, from Palermo, Sicily, discovered Ceres on January 1, 1801, and it just happens to be the largest and most massive asteroid in the solar system. Ceres is 590 mile in diameter and was 164 million miles away shining at magnitude 7.1 in Taurus crossing the Hyades star cluster when this image was taken.

Ceres is still in Taurus, but has since moved off to the west and now lies south of the Pleiades star cluster. Although it is currently 203 million miles away it is still relatively bright at magnitude 8.2 and is an easy target for binoculars or small telescope.
