I'd like to embed a QHY guidescope and camera semi-permanently inside a Mach1. That's good for polar alignment because it has better accuracy than, say, the Polemaster and being attached to the mount

Can you post images for the 130GTX? It would be useful to see them.

OK I've got it now. The feature I am talking about is called "Client Isolation." On WiFi networks you can have Client Isolation which means that clients can't talk to each other. You can turn it off i

The GTOCP4 is a DHCP server. It allocates IP addresses 172.31.0.100 and 172.31.0.101 to two computers. It doesn't need to act as a switch or a router right?. The two computers should be able to talk t

I can get an iPad and a PC to both be simultaneously connected via WiFi DHCP to the GTOCP4. They can have IP addresses that differ by 1 in the last digit so are on the same network. But they can't tal

What is the minimum firmware for these updates?

Google "skylist" to see example skylist files. You can find a whole bunch of them at https://www.skysafariastronomy.com/repositories/index.php?dir=skylist&theme=onyx In MATLAB: fid = fopen(outfilename

How do you get the points out of an APPM model? Can you get them into a text file? If so then it's easy to get them into SkySafari or Luminos. If you are interested I can explain how. I don't know how

Would you do the same jumper if both your power supplies were batteries?

If you can get a star, which isn't very likely, you can get PHD2 to guide on that star and apply a lunar offset (which Cartes du Ceil can provide). It might be worth using a guide scope pointed near t

You can use PHD2 to do comet guiding. Use Cartes du Ceil to send the tracking correction to PHD2. You can Google for full instructions but it's actually quite easy.

I have decided to build a wooden pier for my Mach1GTO. Wood is much easier for me to work with (as opposed to concrete) and is a natural extension for me from a wooden tripod. I have tested wooden pie

YCSD mini PCs have versions with 6 or 8 USB ports. I haven't used one but I'm tempted.

I don't have any experience with pole piers. But for a Mach1 and 130mm refractor I can't image them flexing much. I should go and observe some telephone poles in the wind. But vibration - why do you t

How about poles made for retaining walls? Treated and designed to be placed directly in the ground. The local supplier guarantees them for 50 years. Cost under $100.

I've seen a lot of charts like that one that are misleading due to either (1) wrong y axis scale chosen or (2) wrong focal length entered for the guide scope. The critical number is the RMS which in y

Apparently, there are galaxies in the centre part of the Helix. Can someone point them out to me?

No need to go "some more" beyond finger tight. I have actually forgotten to tighten the clutches at all and not noticed - slewing and guiding still worked.

Ray I can get the mount's time from the site tab but then I have to manually set the computer to that time - a bit of a pain to do with any accuracy (but good enough for most purposes). The computer i

APCC feature request - Get time from mount. We can get latitude and longitude from the mount, time is useful too. This is for people who run PCs that are not connected to a network but are connected t
