The problem could also be the Dec home switch. If it fails to find the home position when you first power up and start the alignment it is probably the culprit. Usually it take a small adjustment to make sure it closes. If that works right then I would suspect the cables as mentioned in other posts. The jacks can get dust or debris in them that can cause the encoder data to not reach the controller.
I had a CGE for many years and it was a great mount.

So...I wanted to try something different to get "up close and personal" with galaxies so I tried an experiment imaging NGC4565 by attaching an ASI-482MC non cooled planet camera on my Ultima C8 on my GEM45 mount. I figured that with enough exposures and dithering I could get a smooth image. As usual everything was working against me...the seeing was bad, the scope was a bit out of collimation after the 200 mile road trip among other things. I exposed 100 x 120 seconds captured and processed with Astroart 8. But even with all the issues I think the experiment was a success. I am a bit amazed that a non cooled planetary camera could work this well on a DSO. I will be working with this setup during galaxy season to see if I can get it dialed in and hopefully I can get a night of good seeing to test it's full potential.

This is what ZWO says about the ASI482MC and the large 5.8 um pixel size are some of the reasons I decided to try it for galaxies.
SNR1s=0.08lx
Sony is introducing SNR1s [lx] as an index used to quantitatively evaluate picture quality at low illumination. SNR1s [lx] is an acronym consisting of “SNR” (Signal-to-Noise Ratio), “1” (represents that the signal level when noise = 1 is 1), and “s” (for Security). The lower this value is, the greater the image quality will be at low illumination.
The 5.8um large pixel size allows unprecedentedly low SNR1s value of 0.08lx for ASI482MC. While ASI385MC is 0.13lx, you may see it is almost 2 times better, which brings the camera a fantastic nickname – “The King of the Night”.
The amp glow is not too bad either.

Player One just announced that they are coming out with a 294 camera. I wonder if they have tamed calibration issues ?????

Is it the Starbook 1? Is he connecting via LAN or ST4?
The Starbook 10 works like a champ, not sure about earlier versions
It is the original Starbook so it is probably the version 1. He is trying to connect via the Lan. I am not sure if he has tried the ST4 port.

Thanks for your response...
Sheldon has the original version of the Spinx mount and StarBook and everything else seems to work OK. Guiding calibration keeps failing.
His guide scope FL is set correctly and he knows to not calibrate in the polar regions.
Where is the "tracking toggle" located in the ASIair + software ???? Can you do a screen shot ???

I have a friend that is trying to use a Vixen Spinx mount with his ASIair and he can not get it to calibrate for auto-guiding. His Spinx has the early version of the Star Book which is in the list of supported mounts in the ASIair. He says it seems like it is moving too fast when it tries to calibrate like it is not set to the guiding rate. Has anyone seen this behavior?
So.....Has anyone been able to get the Spinx to work right with the ASIair?

I love it. It looks like a flying bird.
I think it is commonly called the Seagull Nebula. (^8
I love B&W Ha images.....they stand well by themselves.

This is the only picture I have ever seen of a Superscopes mount until your post. I found this picture on the web more than 20 years ago and there was no info to go with it so I don't know who took it or who the scope belonged to. Maybe someone will remember seeing it.
I always thought it was beautiful and well engineered and that is why I still have the picture in my collection.

Great image....This one is going on my "To Do list"

This filter looks very interesting since it includes the blue channel. The star colors look more natural without having to process the stars separately and the nebula color is not orange like it tends to be with some filters . I just installed Siril to go along with Astroart 8 and I hope to be able to improve my processing skills. Unfortunately I don't enjoy processing as much as I do image capture so it will require some dedication on my part.
This filter is going on my "want list".

The color is quite pleasing....I need to check out that filter.
Great image !!! Especially when you consider the short exposure time under such difficult conditions.

224mc vs 482mc

I chose the ASI482MC to do some galaxy imaging with a C8 at 2000mm. Despite bad seeing and a some slight collimation issues the camera did a great job.
