Your going to need an EQ Direct Cable with a DB9 adapter for the EQ6. pegasusastro.com/products/eqdir-usb-stick-for-eqmod/
You can of course make your own.

Get KDE Neon running on a laptop and install KStars and Ekos. Get comfortable with how to use Ekos for polar alignment, plate solving and slewing your mount around. Then start adding devices as required. When your happy using a laptop, dive into the threads in the forum to learn how to set up a single headless RPi3/4.

Its a journey, you'll have fun for sure.

It was the damn power supply. Unfrickin believable. Shame on me.

Keith Cobby created a new topic ' RA DEC Jumping Around' in the forum. 10 months ago

I've seen a few posts but couldn't find a solution.

My RA and DEC Eq coordinates keep jumping around causing all sorts of problems using my HEQ5 and USB EqDirect Cables (I have two Eqdirect cables from different manufacturers and the same issue with each). Doesnt matter if scope is parked/unparked at home position or anywhere. Cross hairs in KStars match the jumping coordinates.

This does not happen with my EQ6 Pro set up. HEQ5 Pro works fine with the hand controller and also using my Synscan Wifi module.

This issue also stops me from Enabling Debug. As soon as I Enable it, it gets Disabled.

Any ideas?

For any guiding issues I highly recommend double checking your polar alignment. The Ekos tool is awesome for this.

5 pixel dither,15sec settling time, 2sec guide interval, 2x2 bin might be a little bulky.

2 pixel dither, 5sec settling time, 1 sec guide interval, 2x2 bin would be lighter. Shorter 1sec guide intervals will allow the mount to react quickly and not have to keep trying to catch up.

That's an interesting factor to determine correct exposure. When you say within '3.5 and 5' what parameter are you evaluating?

Is it possible to create a feature that allows the user to select an area within an image in the fitsviewer to give a targeted opportunity to critique background DN / ADU e.g a moveable box of say 10x10 pixels that shows the user some appropriate stats (Min/Max/Mean/Median). The mean/min/max of the 100 'background' pixels could be a useful value to quickly determine exposure. The Fits Viewer currently produces DN values for the whole image so why not for a user selected area. Maybe a mouse over would be the simplest.

An ability to add a variety of user defined positions would be very handy; Park, Home, Flats Screen, etc...

Bringing your exposure down to 1sec could help. Add a dark frame also. This may allow you to then bring down the minimum correction pulse length. You can guide using quite faint stars. I can get 0.6-0.7 all night long on a still night.
