brrttpaul Posted February 19, 2016 Share Posted February 19, 2016 Ok so looking at guide scopes, I mainly use my equinox ed80 but I also have a skywatcher 150 refractor. Is it possible to fit a guide scope to my ed 80? been looking on FLO and the only one I can see is this one skywatcher startravel 80, but would that be roughly the same size as the imaging scope? I have seen smaller ones but cant think where about 50mm, I would also need a foot?plate as the equinox I have hasnt got anything on there. any suggestions most welcome Link to comment Share on other sites More sharing options...
Psychobilly Posted February 19, 2016 Share Posted February 19, 2016 I guess you talking about finder guiders... where a 500 mm finder is "adapted" to use as an electronic "finder" and guidescope... There are a range of adaptors available to adapt the more "popular" finders to take various "cameras"... http://www.modernastronomy.com/product-category/accessories/finder-guider-adapters/ Peter...

PeterCPC Posted February 19, 2016 Share Posted February 19, 2016 See my other post in Dither but a 50mm Orion guide scope that mounts on the synta mount is fine. Peter Link to comment Share on other sites More sharing options...

Thalestris24 Posted February 19, 2016 Share Posted February 19, 2016 Hi a SW straight through 50mm finder plus adapter pplus Altair GPCam mono would do you. The Equinox 80 should have a finder shoe? (Looking at FLO pics) Louise Link to comment Share on other sites More sharing options...
PeterCPC Posted February 19, 2016 Share Posted February 19, 2016 This is an old ED80 without a finder shoe. Peter Link to comment Share on other sites More sharing options...

Peter Just get an extra tube ring (or preferably 2! then use a small plate to join the rings), you can position the guidescope wherever it's convenient by rotating the rings around the main OTA. This provides a very solid mount for your guidescope. ChrisH Link to comment Share on other sites More sharing options...
Thalestris24 Posted February 19, 2016 Share Posted February 19, 2016 This is how I fitted mine: I used an Al bar and pipe clamps - cheap and rigid! Louise Link to comment Share on other sites More sharing options...
wuthton Posted February 19, 2016 Share Posted February 19, 2016 The finder bracket you linked to in your other thread just doesn't look up to the job for me. Your mounting arrangement should be like Louise's, something absolutely rock solid. The tiniest amount of flex will ruin your guiding. Link to comment Share on other sites More sharing options...

brrttpaul Posted February 19, 2016 Author Share Posted February 19, 2016 I understand the need for a better mount but it comes with it, I havnt seen no 9x50 scopes only, its something i need to look into Link to comment Share on other sites More sharing options...

richyrich_one Posted February 20, 2016 Share Posted February 20, 2016 Or if you want to align it with the main OTA as well... Link to comment Share on other sites More sharing options...
brrttpaul Posted February 20, 2016 Author Share Posted February 20, 2016 the rings and the scope look a good idea its the dovetail bar thats the problem (ok i can get a shorter one but attaching it to the scope I would need another set of rings wouldnt I? I just cant see where these would fit on an Equinox ed80, its short even when the dew shield is out plus the shoe on the bottom isnt in the middle its nott going to leave much room Link to comment Share on other sites More sharing options...

brrttpaul Posted February 20, 2016 Author Share Posted February 20, 2016 Guys its doing my head in with these rings lol, the way I see it atm i would have the equinox 80 (with the foot removed, on that two tube rings with a dovetail attached top and bottom, on top of that then my guidescope attached to the dovetail with two smaller rings?, So I would need to purchase two sets of rings and two sets of dovetails (along with the guidescope and guide cam. Looking on the altair site there is a complete kit (camera,scope etc) not knowing anything about cameras etc is this a good kit? I also read that I wont need to be as stable with it being such a short focal length so that,s a plus surely? I realise im probably playing on your nerves with 40,000 questions but just want to get it right, heres the link of the kit http://www.altairastro.com/Altair-GPCAM-50mm-Guide-Scope-Camera-Kit.html Link to comment Share on other sites More sharing options...
PeterCPC Posted February 20, 2016 Share Posted February 20, 2016 Looks fine to me. You will still need to fix the shoe to the scope. Peter Link to comment Share on other sites More sharing options...

Thalestris24 Posted February 20, 2016 Share Posted February 20, 2016 Hi It's probably worth getting a set of 90mm cnc tube rings for mounting the ota, anyway Louise Link to comment Share on other sites More sharing options...
brrttpaul Posted February 20, 2016 Author Share Posted February 20, 2016 I was going to do that anyway plus a dovetail as I have a bigger scope also and if I wanted to put the guide cam /scope on that I could. What I did notice though with the dovetails and the tube rings , which ones supply the appropriate crews? do they come with the dovetails or the tube rings? also why does the one tube ring have a sort of adjustment ring (on top back ring) is that for the guide scope? (up down type of thing?) Link to comment Share on other sites More sharing options...
Alan64 Posted February 20, 2016 Share Posted February 20, 2016 That's for attaching a camera directly to the ring, and as the sole imaging device; "piggyback" it's called. It's removable; and yes, for mounting a guidescope using both tube rings. Link to comment Share on other sites More sharing options...

(up down type of thing?) Hi If your scope didn't come with cnc rings and a dovetail you'll have to buy them separately. The cnc rings on my TS Apo (above) have screw holes - M5, I think. Obviously, adding the aluminium bar as I did, necessitates sorting out some suitable screws. There is some advantage to using the rings with adjusters for the guide scope. They aren't essential but facilitate lining up the guide scope with the imaging scope so they are both pointing at the same spot. That way you can see your target in the PHD2 guiding image.
