  1. Thanks everyone, especially vlaiv for making me feel less of a fool! I guess one of the pitfalls of reading lots but having little experience is sometimes not having good perspective on how significant an issue is, or is not. 40 years in electronic engineering, where indicators close to the right and in the red make me very uncomfortable probably didn't help . All the best Michael
  2. I have a Sky-Watcher Esprit 80 ED with matching field flattener which will sit on my newly acquired, mint condition used NEQ6 pro (thanks Michael). I recently purchased a 2nd hand QHY-10 OSC camera - I have to admit it was a spur of the moment decision without investigating camera /scope matching. The CCD Suitability Calculator at https://astronomy.tools/calculators/ccd_suitability tells me it wasn't a great choice and that I will be significantly under-sampling (see below). As I see it my options are: Do nothing. I'm still learning and can use this setup to improve my knowledge and skills at aquiring images and processing them. At some point the under-sampling will be the limiting factor and I can decide then whether I want to change camera, scope or both. Change the camera for something around the same cost 2nd hand. If I do that does anyone have any suggestions or recommendations? Change the telescope to suit the camera. The tool says it is a good match for the Esprit 120 but a good used one is probably outside my budget zone so I'd be looking for recommendations for a good 120mm refractor under £1000. The smaller field of view would annoy me at times but I'll probably go there eventually. Change both. I like the simplicity of the refractor but I could investigate different scope types. I probably like this option least because I'm just reaching the point I'll be able to set everything up, polar align, get on a target and guide well, enabling me to get good amounts of data for processing. Up to now every night has been more experimentation, fixing problems or just getting everything running sweetly and the clouds drift over to watch me Any thoughts, experience or advice would be most welcome. Michael
  3. I've used 2x 10m active USB cables in series to a passive USB hub which connected to my Canon 7D Mk 1, EQ5 mount and starshoot autoguider camera. Not a setup anyone would advise but I had the bits and it worked perfectly! I'm in the process of upgrading including installing a pier - I won't be using this setup much longer. Michael
  4. I'll take this at £14 if its still available, thanks.

      Hi Michael. Sorry, I have a buyer in already. If anything doesn't work out I will get back to you.

  5. WiFi is great but people tend to forget it's really for when you can't be plugged in. My house wifi has 4 phones, 3 laptops and a tablet that all use the WiFi. TVs, media server, NAS and security cameras would add even more if I hadn't cabled them all. Add to that the 100 year old solid walls of the house and I'd be fighting for every packet of data even when everyone else is asleep! The pier is only 3m from the house at it's closest point - carefully positioned so I can see Polaris but not the two nice shiny LED streetlights, one either side of my house! I hadn't thought about beefing up the earthing but I guess the I can get a benefit from the wire armour being tied down at both ends. I will be running a signal earth anyway to avoid any issues with induced noise etc. All the best Michael
  6. I'm using a USB extender cable at the moment but the permanent cable route is far to long and I want to avoid wireless if I can. That's exactly what I need. I saw and replied to Shimrod before seeing your post but both devices will do the trick. Thanks Michael
  7. That is exactly what I need - thank you! I'm already using two Pi 4s - OctoPrint and OpenMediaVault but I think I'll get my setup working as is before tackling Astroberry - one step at a time! Thanks Michael
  8. Thanks for posting but I really do mean something that can combine the USB connections to my devices and then transfer the daya down a CAT 6 network cable. I've got hub similar to the one you show and feed the data down a USB extender cable at the moment but I'm doing a permanent installation to a pier and the cable route is way too long for USB. All USB to network adapters I can find seem to be for adding wired network to a computer using a USB port so I don't know if they would work directly to devices. Michael
  9. Thanks folks but I did mean 'wired' ethernet. I have been using a USB extension cable up to now but I'm putting in a pier and running a data cable from it to my home hub so just need something to interface with the devices. WiFi is great but I live in a 100 year old house with solid walls that seriously limit coverage. I hadn't thought of looking for some sort of 'point to point' Bluetooth or WiFi device where I could have the receiver on the wall outside and wired from there so I'll look into that. All the best Michael
  10. Hi I'm working on remote access for my setup and am looking for a USB hub which can connect my cameras, mount etc to the laptop via ethernet. There are quite a few on Amazon etc but most seem designed to plug into your computer to get extra USB plus wired ethernet. An example on Amazon Does anyone use such a device which doesn't need connectedto a computer, or know of one they'd recommend? Thanks Michael
  11. There are quite a few online courses including this from the Open University. https://www.open.edu/openlearn/science-maths-technology/comparing-stars/content-section-0?active-tab=description-tab Michael
  12. There's no way I'm trying to explain bringing welding equipmet (or a welder!! ) home - my wife already tolerates me spending lots of time with "...whatever the hell all that stuff you play with is..." so I'm not rocking the boat . A friend thinks a blacksmith he knows might help so I've drawn up plans for something more traditional (I like playing with Freecad anyway) Thanks especially to tooth_dr, Davey-T and Starflyer for pictures and information. I notice that most piers have a mount adapter plate fitted but I thought I'd achieve the same effect with an extra plate at the top cut out to suit the mount. All being well I get one made for my EQ5 and another sized for an EQ6 head which I plan to upgrade to at some point. Edited to add it has a 'Slenderness Ratio' of 43 from Kevs spreadsheet using 150mm diameter 6mm walled pipe. All the best Michael
  13. That's exactly the sort of thing I'm looking for. I don't know anyone who could do welding, which is why I started on the path of getting plate cut and bent for self assembly. I'll price my idea anyway and ask around to see if anyone I know knows anyone who knows someone Do you have a sketch or plan for that which you'd share? Thanks Michael
  14. I'm looking for a bolt down pier suitable for my EQ5 and a future upgrade to an EQ6. I'm in Glasgow and can collect, will go a fair distance for the right thing. Thanks Michael
