    Replacement part for my Meade mount (3D printed)

    Absolutely. It's a challenge to try to reproduce something you already have in a way that can be printed and work as intended. James

    I'd have thought an engineering place should be able to repair the original part, assuming you can find one locally. James

    Nearly there with the second side now. Should finish that tomorrow. Then it's a case of welding the sides to the roof, which is when we find out how square I've managed to keep everything. James

    I was trying to avoid opening that particular catering size can of worms :) James

    What did the postman bring?

    They'll pry my 12.5mm and 18mm BGOs out of my cold, dead hands. I have the full set, but these two are particular favourites. James

    Just been out trying to get a bit more welding done. I like to have the workshop door open when welding so there's plenty of ventilation. Unfortunately it's rather breezy here today and it's not making life easy. I might have another go later. James

    Is that because you can't completely disable updates with W10? Sounds like a case for firewalling it off from the internet during imaging sessions. James

    Nuts and bolts ordered, and a little more welding done this evening. Have one side complete now and started on the other. James

    Looking very smart. Hopefully driving to Cornwall and back won't take all week. They have roads down there and everything these days you know :D James

    Got most of one side made up today, but lost a couple of hours due to a swimming club committee meeting. I hope I can get the rest finished during the week though there seems to be so little time. I'm going to make up both sides and then clamp them together at the correct spacing for the rails, then weld the rest of the roof to them. It's a bit more of a faff to do it that way, but ensures the bit I really need to be spot on is actually correct. I also sorted out how I'm going to mount the wheels Which reminds me, I must order some more bolts, washers and nyloc nuts (which I'll use instead of the plain ones in the photos). I might get them in stainless, come to think of it. Might be useful if they didn't corrode in the damp. James

    This afternoon I found I could get rid of the coating and together with turning the wire speed right down everything started to go right again. I remade a few of the welds I was less happy with (possibly unnecessarily) and then continued with assembling the rest. Not a huge amount more is done, but it's moving in the right direction. They actually feel quite light. I can comfortably pick them up one in each hand. Hopefully I can get some more done tomorrow. I need to join these two bits together, but I think I might make the vertical sections up next, then fix these two in place on top of them before putting the remaining horizontal sections in. Welding will have to be done outside however, so it's a bit weather-dependent. James
  13. An original USB2 ASI120MC could be a reasonable choice as an alternative. Might need the firmware changing to the "compatible" (ie. standard-conforming) version. James
  14. Fundamentally I see no reason why it wouldn't work, though I don't know about the sensitivity of that camera -- you may find it just works better with a camera designed for astro use. Some cameras don't allow sufficient control of gain and exposure (for example) that you might want for imaging. Alongside oacapture (which does work on the RPi though I've never tried with their dedicated camera) I have been bumbling along with a live stacking application which should also run on the RPi. It doesn't have a lot of functionality yet, but it's not a huge amount of work to push it on further. That would probably do for the software side of things. James

    pier construction question

    You can get reducers for the spiral ducting that would allow you to bring the diameter down to, say, 180mm right at the top. That would give you more clearance for the kit sitting on the mount. Something like this, for example: https://www.ebay.co.uk/itm/10-to-6-Metal-Taper-Spiral-Ducting-Reducer-Circular-Adaptor-Hydroponics-UK/263458549045 James
