  1. Thanks guys, I think I agree with both of you - but the opportunity to start from scratch has made me consider everything, hence the question.
  2. I’ve been following The design looks great, so looking forwards to seeing how it goes. How are you dealing with pier isolation? My own thoughts were that with a bent pier I can easily maintain isolation from the obs floor as the footprint is relatively small. With the mesu pier and also with yours, the footprint is obviously much larger. But then I know that there are some strong advocates of not worrying about an isolated pier block and ‘just’ sit the whole think on big slab. This seems simple, although less so at 1.5m high.
  3. My understanding is that yes it can. My question about whether or not to install a bent pier is really just because I'm starting from scratch and so I can. But just because I can, doesn't mean I should, or that it is worth it - which I'm hoping some more experienced people can help me with.
  4. I'm not sure I follow. Do you mean far enough to 'require' the bent pier?
  5. I assume so, but engineering is nowhere on my list of even vague abilities. For now I'm working on the assumption that everything is possible, but it might not be worth the money/space for the added usability. Do you have any views on this?
  6. Yes - I'm still waiting for clarification on this. The Observatory will be next to an existing garage, so from the access road perspective it is at ground level. From the house perspective, because he plot is on a slope, it's raised and will exceed the 2.5m. Like I said above - there are some practical issues to overcome
  7. Something very odd has happened recently, and there have been fleeting references about 'your observatory'. I'm taking this as a tacit acknowledgment and agreement to building one! However, there are some practical issues to overcome, and this will likely be the first of many, many questions. As I have been casually drafting out my design ideas (because obviously I haven't been planning this for a few years) I've been prioritising the problem solving order. The biggest one also happens to be the first as it turns out, which is the pier. The observatory floor will (has to) be ~5feet (1.5m) above ground level, so the pier base will be a reasonably sizeable construction. The position of the pier will influence the layout of the rest of the space, and so this is where I would appreciate your thoughts. The current plan is to install a Mesu e200, but is it worth/necessary installing a bent pier to allow for no meridian flip? I think I will have to have such a pier custom made, which adds a little complexity. Or should I 'just' install a standard straight pier and live wit the (probably quite minor) consequences of having the flip? Thanks for your thoughts.
  8. When I had SynScan my experience was that this is not possible to do natively in MacOS. Running the update software in a Windows virtual environment didn't work either - I had to dual boot into Windows proper.
  9. That was what I started with - it seemed like an obvious thing to try but it didn’t work. Maybe I have the spacing wrong?
  10. Hi I feel as though I see a steady stream of images along the lines of “I just held my phone up to the eyepiece”. Now either I’m absolutely missing something (which is definitely possible) or there is considerably more luck/effort in those images than inferred. I have an iPhone, and seem to have two significant problems using it to grab any kind of useful image. And no, I’m not expecting it to rival a dedicated imaging rig. Firstly, alignment is very difficult. And secondly, focus seems to be impossible. I have one of the Celestron NexYZ phone mounts, which is less steady than I expected but I can eventually get the camera aligned with the eyepiece. But I’ve never managed to get focus. I’ve tried the default camera app as well a dedicated one with more manual control. I’m failing. Overall this is not a significant impediment to my observing. But it would be great to be able to get some reference shots to go with my observing notes. Does anyone have any tips?
  11. Prima Luce Lab Sesto Senso (V1) Robotic Focusing Motor - £150 This... this changed my imaging life! But alas, I'm on an imaging hiatus and so now you can grab yourself a bargain. Please note, this is the original version, not the current V2. Overall it's had a nice life and is in great working condition. As you can see in the photos I had a little issue when I originally installed this, and the underside grub screw thread got stripped. I re-tapped it slightly larger (and slightly off of vertical which was not intentional) and whilst this is mildly annoying, it has not impeded function in any way. I used this with INDI/EKOS and it is ASCOM compliant. I bought it new from Rother valley Optics in 2018 for £329. There a couple of reviews on SGL about this focuser if you would like to read and see a little more about it: Any questions then please ask. Price includes postage to mainland UK. Payment by bank transfer or PayPal (buyer pays fees). Justin
  12. Baader 1.25" filters with very little use. Optically pristine. Clear - £ 18 Leftover from my foray into imaging, which is now paused. This very useful addition to the Baader filter range is intended for the luminance channel in astro imaging. Using narrowband filters can often result in slightly dimmer images, which can be difficult to resolve to a focus. You can now use this filter to focus perfectly with a bright image and since they are also parfocal, switch to a different narrow band filter without loosing the focus. This filter has the same substrate thickness as the other Baader filters. Halo and ghost free. Baader balances each dielectric coating stack to avoid the ghosts and annoying halos that plague other manufacturers filters. 10nm Solar Continuum - £40 SOLD Postage included to UK mainland. Payment by bank transfer or PayPal (buyer pays fees).
  13. I thought about ‘constructing’ something but despite the implication of missing Monday, I’d prefer to exchange it for the right product.
