My Old EQ3 with a New Hand Controller

The main piece of hardware, along with its testing devices

So here’s the problem: I like redundancy and I like control, fine grained, precise control of my devices. These are obviously not the aspects that drove me to choose the EQ3 mount when purchasing it, but since it is the mount I have at hand, and no physical room nor real opportunity for something better, I decided to hack this mount.

Independently of Hernán De Angelis who looks like he did a great job, from the same starting point — so kudos –, I got my hands dirty and my screen full of code. (tovább…)

ASI 178MM (cooled), Lunt CaK B600 LS6CAKMDS2, Skywatcher 72/420 ED-APO, mountpusher, EQ3-mod — not ideal, but enough to dig out some protuberances.

Solar Prominences in CaK, 2022-02-25

It took a lot of editing to dig out of the unfavorable dynamic range the prominences, but I think I did a decent job. ASI 178MM (cooled), Lunt CaK B600 LS6CAKMDS2, Skywatcher 72/420 ED-APO, mountpusher, EQ3-mod

The Sun in narrow band CaK, first light 2022-02-24

There were a few relatively clear minutes around the Sun today, so the new gear, ASI 178MM (cooled), Lunt CaK B600 LS6CAKMDS2, Skywatcher 72/420 ED-APO, mountpusher, EQ3-mod got its chance to gather its first light. It is impressive how much more details and even prominences at the disk’s margin are almost readily visible. The B600 is very near to the limit of this setup, the vignetting is obvious when a bit misaligned. Next time one throws a big bag of money at my feet (don’t hit me with heavy bags, please), I’ll buy the B1200 or even the B1800. Even though the final image is, when viewed at a low resolution, looks similar to my previous ASI 178MM (cooled), Baader K-Line Filter 1.25″ (double stacked), TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod images, the similarity arises without the post-processing, already in the live view. For the wider Baader filter, I apply an enhancement we might call “brighten is brighter than the context”, different from local contrast or global contrast application. Reflections and a bit of maybe astigmatism may be inherent to the system, but it’s something present in the Baader cell too.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
