  1. Hi all. Does anyone on here know of a little engineering shop, or have used one before, or even own a lathe!

    I just want some spacers adjusted by turning some material off etc.

    Cheers. David


  2. Here we have a brand new Ioptron Polar scope to fit Celestron AVX mount. Also fits CG5 according to the sales page.

    Contains polar scope, adaptor, cable and box. This system uses your laptop or pc to line up a cross with a circle. Pic below from web page.

    Cost £199 selling for £105 posted in UK and bank transfer or Pay pal (fees paid please) to pay. Thanks! David

  3. All items now sold thank you!!

    Hi folks. Due to an upgrade almost before I got started, I have the following items for sale. Pictures are all below.

    So to start, I have a Celestron AVX mount in very good condition. This is hardly used. It has the ADM upgraded dual saddle, Losmandy and Vixen, and the orange replacement clutch levers.

    Next I have the following accessories for the above mount, but will sell separately no problem -

    Celestron Star Sense Autoalign. Boxed with instructions and unused. £199 plus £6.50 postage.

    OK, this isn't a chip distance so I very much doubt that it will be all that critical. SCTs can cope with a considerable range of backfocus but are optimal at a certain distance. I'd be amazed if this were critical but I'd ask those imaging with the scope. If you don't get a reply I'd just suck it and see. I'd certainly do that in your shoes.

    Olly

    Thanks Olly much appreciated!! I think it's easy to fall into the trap of thinking it has to be within 0.001 or something!!

    I'll give it a try +- 2 mm or so!

    I don't think you're talking about focal length here unless there's a typo. You're unreduced scope has an FL of 2000mm becoming 1400mm with the 0.7mm reducer. Where does this figure of 133mm come from? Without the reducer you just focus and shoot.  With the reducer you need to respect the 'chip distance' between reducer and chip. Maybe this is your 133mm? If so you'll need to add about 1mm for filter effects but with smaller chips very high precision isn't usually needed. But first let's clarify the 133mm.

    Olly

    Thanks mate yes I didn't word it very well it's the camera to Scope back focus measurements. It's supposed to be 133 mm from the scope back thread to the camera sensor. I've been able to make up adaptors like the ones shown here but just wondered how critical the size is. Maybe it's just a guide and possibly extra shims etc are needed? If so I'll try to put a Baader adjustable Vari adaptor in the chain for future adjustments?

  7. Hi folks. I'm setting up my ZWO 1600 with my Edge HD and filter wheel.

    The length required is 133mm.

    The question I have is how critical is the 133? With included spacers I can make 132 haha. Or is there a better way to go, plus or minus the figure.  Or could it be a case that once set at 133 it may need adjustment anyway?

    New to this so all advice welcome+

    Cheers. David


  8. I tried a few different cases over the last 12 months but did in the end settle on using a company called AnyFoam for the inserts. You just send measurements and it costs about 3 to 4 quid a sheet. Easy then to cut with a Stanley blade.

    Some nice plastic cases off Amazon which should be ok outside during observing.

    Still need to cut out for the 17 Ethos once it comes in from FLO. And I know there are overlaps etc - I use them on different scopes!

    The last picture still needs doing - it's my In Progress box !!

  10. Hi all. Today I received from FLO my C11 OTA and I'm keen to improve the finder mounting.

    On my 8 inch Edge HD I bought a universal Baader finder bracket but obviously the diameter of this scope is larger. I'm not keen on the Celestron holder with it's rubber O ring.

    Anyone used anything different on their scopes please? I suppose I could get one of those ADM dovetail bar kits and mount it on that?

    Cheers. David


  11. Hi all. I've heard on here there's no such thing as a daft question so go easy!!! Lol

    So if you take 2 ep's, both 10mm.

    One is 68 degree and the other 100 degree FOV.

    So looking at a Planet or Nebula for example, does the object look the same size but see more of it with the 100?

    Cheers!

     


  12. Hi all, today I ordered the CEM60-EC mount from the fine people at FLO.

    I already have the mini pier all ready for it to go on. Also ordered a set of counterweights and extension bar.

    Full report and pictures to come once I have it delivered!!

  13. Hi all. I plan to try out the ASIair on my AVX or Skywatcher mount with Esprit 100 scope. In time it will hopefully be to do some imaging. But before that can the unit be used with a tablet / Sky Safari as a goto tool?

    I imagine the scope would need to be at least roughly polar aligned first.

    So can I use the Wi-Fi from the tablet to ASIair to slew to targets selected on the app?

    I thought it would be a good introduction before I add my imaging and guide cameras.

    Thanks. David
