It’s basically a full upgrade kit then? Thanks for your help.

I know this topic is extremely old but it’s been a project in process. Due to lockdown my interest in astronomy has been revived. My question is can I replace my stepper motors to speed up slewing? The original motors are too slow to slew and I would like some more speed. I want to keep the board and the gears but just change the motors. I think they maybe nena 17? Information on motor sizes, power and dimensions would be appreciated. Is this possible?

Thank again kens

Does PHD2 or APT give a man identification and location of object through the skies?

Thanks for the reply. Once I’m on the target manually, and locked on, I guess I don’t need to worry about the slow slewing? Do you mean the only way that I will know where I am is by the setting circles, or is there another more visual way?

If I am on target for setting up the hardware. The next problem will be the software. With Cartes du Ciel which connection driver do I use?

Ken’s. It sounds like the mount is sorted? I just need to get the right camera?

Paul 779. Thanks for your help. The GPUSB is wired into the handset which is connected to the mount. It doesn’t have a ST4 port. I think I can connect the camera, which will be fitted to 9x50 finder scope, directly into the PC. There is something I just can’t get my head around here?😂

I understand that you can connect camera directly to PC? What is the GPUSB for? is it a direct replacement for an ST4 Port? Or do I still need a ST4 Port to connect HC to PC? One last thing, I do not have separate leads exiting the HC for RA and DEC. It is a telephone jack that fits directly in the mount. I guess this is not a problem just a later adaptation from EQ3 mount?

On further study, if I cut the plug off the crossover adapter and wire it into the handset this would give me a ST4 port. I could then buy a ST4 to usb cable to connect to PC. I am confused as to what the GPUSB connection to PC does? I thought it did the same thing? Would any of this work? Thanks, in advance for any help.

I got this with it as well. I guess it’s redundant? The black ends takes the handset. The other end is a larger and I guess fits into a ST4 port but I don’t have a socket on the mount for it. Thanks

The handset plugs into the mount where another cable comes out of the handset and is wired to GPUSB which plugs into the computer via USB. Would this be suitable for connecting the mount via ASCOM? Then the guiding camera would then be directly connected, via USB to the computer. Thanks

The handset has been modded with GPUSB box.

Thanks Olly for replying. I’m happy that I am there or thereabouts. The camera I intend on buying is a BRESSER MikrOkular Full HD Eyepiece Camera. (I know. It’s probably the cheapest astrocam in the world). It does not have a ST4 port but I have seen YouTube videos where astrophotographers prefer not to use their ST4 ports and so I cannot connect to the mount. That is why I was wondering if the camera is just directly plugged into laptop? My mount does not have a ST4 port either, only a socket for handset input. (Not sure if this a ST4 port). I will watch some YouTube videos on PHD as I am not sure how the telescope interacts with the software and what, or how, it all works. Thanks again for your advice.
