My old EQ3 with a new ST4 port

UPDATE 2022: I reimplemented the whole hand controller on an ESP32 micro, from the ground up. See this article.

On cloudy nights astronomers sleep still do some astronomy, or just something, in order to be doing something. What I did last night: take out my old EQ3 mount — motorized but no goto and no autoguider port — and think about it a bit. After some thinking and measuring, I added a standard ST4 autoguider port to it. While I know there are others who have done so before me, I remember reading some articles a few years back, for this project I didn’t bother to google that/those articles again. Cause it’s not rocket science.

And cause I already have my soapbox driving the HEQ5. Actually I have two soapboxes, so let’s rock.

So I opened the black box the hand controller literally is, to see what’s under the hood.

The Soapbox MountPusher Guider

the interface on top of an image acquired with the guiding solution

I have the following problem at home: the balcony is small, the tube is big and I am lazy. This sums up to a constant problem of drifting, the planet or lunar surface being imaged slowly walks away. Though there are methods to polar align a mount even when there is no way to see the north pole, the small balcony part means frequent small bumps into the whole thing. The oversized scope is also prone to accidents. I also tried the feature tracker in Sharpcap, failed, and the autoguiding of PHD2, failed. So I came up with the soapbox ensembleI call it noszogtató in Hungarian, for it means something like nagger-pusher-convincer. It got itself a soapbox, literally.

UPDATE 2019-09-30: I extended the hardware and the software.

UPDATE 2020-05-10: I extended the hardware and the software. Lots of additional functions added.

Jupiter, Saturn, 2019-06-08

The setup is the usual, ASI 224MC, TSO ADC, N250/1200, HEQ5 with the home made motorized focuser and the home made arduino noszogtató mount guider. I would like to call this the soapbox project — it is mounted inside a soap box, though in Hungarian and Romanian we use soapbox to denote compact and dumb cameras 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.).
