I am beta testing the new WiFi nFocus from Rigelsys. I have set it up on the Celestron C6. The people at Rigelsys have worked with me to find the right fit for the C6 focuser base and have sent out this one. It installed easily with two screws and I am controlling it via the on-board PC: I use remote access to the PC via Windows RDP.

I use APT (Astro Photography Tool) for my imaging and via ASCOM, the nFocus interfaces well with APT. Upon connecting to the focuser in APT, it calls the installed nFocus software.

For an official announcement from Rigelsys on this new WiFi nFocus product, see this link to CloudyNights.com here.

Sprint weather is back: clear skies for two days and temperature is around 45deg F. Moon is over half phase. Bright, but I managed to capture these two images of it on April 2nd and M37 on the 3rd. No filters. The first image of the moon is a little over processed – sharpened. Exposure: 1/125 sec. ISO 100. Imaged with a Canon T3 and Celestron C6 on Skywatcher EQ6-r mount.

M37 is a stack of 10 images during this moon – lights only. It is not a good image, but this was a quick take with no filter during Moon. Messier 37 is the richest open cluster in the constellation Auriga. It is the brightest of three open clusters in Auriga and was discovered by the Italian astronomer Giovanni Battista Hodierna before 1654 (Wiki, 2020).

Tinkering in the basement with the Explore Scientific AR152: I had installed it on the older Meade LXD75 mount. I am currently calibrating the telescope, as it has severe astigmatism.

The AR152 will be used for visual use only as the optics (a doublet) have not passed my tests for astrophotography – Stars have blue edge and are just not sharp.

In the background is the next project: a restore of a vintage Meade 6600 – a 1986 6″ Newtonian reflector with original stained wood tripod. The mount has no drive; just adjustment knobs. There are plenty of dents and scratches on this one – I have used it over the decades in the field and it shows.

Made some changes on the C6; it is ready for first light. At the time of this writing, it is in the middle of winter in Northern Ohio – cold and grey skies. I usually take a break from astronomy at this time of year; as the older I get the less I like standing out in the cold. The tinkering is done and this rig is ready for work. I have been thinking about setting up an observatory for it, using a shed from Home Depot: modified, of course.

I have just set up the alignment of the finder, autoguider, and the main OTA with the help of an artificial star.

I have received and installed an eyepiece shelf on both of the EQ6-r mounts. The shelves will be used to hold the power bricks that power everything (including the Pegasus box). Purchased at Otelescope.com

Equipment update: out with the new, in with the old (yes, that’s right).

I had disassembled the 10″ Schmidt-Newtonian and cleaned it: there were small spider webs in it, and the mirrors needed cleaning. It was Collimated and mounted again on the main Skywatcher EQ6-r mount. Another EQ6-r is going to be purchased soon for alternating use by the Explore Scientific AR152 (for optical use) and the Celestron C6. The C6 is being used for DSLR. It is currently sitting on an old Meade LXD75 mount but the Orion autoguider cannot be used with this mount – I prefer to get another EQ6 to resolve this.

The Explore Scientific AR152: Let’s just say I am replacing it with my 6″ Celestron SCT…Explore Scientific does make quality products, but it seems in my experience and opinion that sometimes defective things can slip through quality control.

When I had received it, the light shroud and entire objective lens assembly was loose and I could move it from side to side. I called Explore Scientific and told them the model was an AR152 and the support person said that this was normal and that the light shroud was designed to move up and down the tube – he was wrong; as this cannot be done on the AR152: the technician was thinking about another model.

I had found that the objective lens assembly was held in by only one screw – the other two were stripped (probably on assembly by too much torque) and laying within the tube; and fell out when I removed the objective assembly. I had to replace the screws and it is now on the tube is on solid.

I have tried laser collimation, but this did not eliminate the chromatic aberration but it still persists.

This is the first and the last Explore Scientific product I will own. I will fix the issues with this AR152 and use it for visual observing only – as it is a telescope for basic visual use only and not for any kind of advanced imaging.

The C6 – prepped and ready DSLR imager:

Celestron C6 with right-angle finder w/illuminated eyepiece, Orion StarShoot AutoGuider Pro & 30mm Ultra Mini Guide Scope, and and old trusty Cannon T3. The old Meade LCD75 mount that this is currenly on will soon be replaced with a second Skywatcher EQ6-r.

I use APT for image capture. Here is the release email customers have received:

APT 3.80 arrived! It brings the highly requested native support for ZWO cameras as well as support for Pegasus Astro and ArteSky flat panels, support for more Canon models, support for the latest CR3 and NEF raw files, GoTo++ improvements, mosaics import from HNSKY or CdC and more.

Update your APT and be ready for the New Moon 🙂

This image was taken in 2016 from Elyria, Ohio USA. Notice that the great red spot is in the center. Telescope: 10″ Schmidt Newtonian. Canon T3 DSLR image. Software: Backyard EOS.

Getting a little better at that post processing. Using Gimp. Image is 180s ISO800, 20img. Stacked with subs, bias, darks. I still need some practice to bring out the luminosity.
