SpoonyPizzas Posted January 18, 2015 Share Posted January 18, 2015 Good afternoon ladies & gents,Now I have a SW 9x50 right angled finder scope is it worth keeping my stock SW 9x50 finder scope?The right angled finder scope is so much easier and I can't see/find a use for my stock finder scope.So do I:-a) bin it sell it - is it worth it because surely all scopes come with finder scopes?c) keep it for another use? (please specify use ) Thanks all Link to comment Share on other sites More sharing options...
ronin Posted January 18, 2015 Share Posted January 18, 2015 Keep it, it is always a backup for when you drop or stand on the right angle one.Easy idea is to go get a plastic storate tub with a lid - I have a 40 litre one - get a lowish profile one and simply put all astro bits in that and put the lid on. Makes the chance of finding bits in 3 months a lot easier. Link to comment Share on other sites More sharing options...
Singlin Posted January 18, 2015 Share Posted January 18, 2015 Keep it to convert to a guide scope. Link to comment Share on other sites More sharing options...
Kropster Posted January 18, 2015 Share Posted January 18, 2015 Keep it to convert to a guide scope.Agreed.Might be a useful guide scope later.It would be a shame to have to buy a guide scope having got rid of the finder for perhaps a giveaway price.

Mark at Beaufort Posted January 18, 2015 Share Posted January 18, 2015 At some stage you may decide to sell your scope (upgrade to 14" or 16") but still want to keep your right angle finder. Its possible that any new scope you purchase will have the straight through finder. So keep it and store it. Link to comment Share on other sites More sharing options...
ghostdance Posted January 18, 2015 Share Posted January 18, 2015 Forgive my ignorance, but what is a 'guider' scope as opposed to a finder? I see lots of references to guiding but no clear idea of the difference. Something to do with imaging?Edit/ I've just read a guiding thread. So, a visual aid to where you point the image-making scope/camera/CCD....Think I get it!? So any small scope can act as a guider to a larger one. Sorry, didn't intend a thread hijack!

Floater Posted January 18, 2015 Share Posted January 18, 2015 My stock finder is in my bits and bobs drawer, mostly for the above reasons.And as per my sig., I have plenty of finders ... :-) Link to comment Share on other sites More sharing options...
Scott Posted January 18, 2015 Share Posted January 18, 2015 suggesting a guide scope to a member of the dob mob....what were you thinking .Me, I'd keep it but that's just because I'm no good at parting with any of my astro gear Link to comment Share on other sites More sharing options...
Charic Posted January 18, 2015 Share Posted January 18, 2015 Don't sell it just yet! someone will wan't one, one Day, to replace a dropped one (ouch!), and as you so much like the RACI, when you sell your scope, you`ll need to refit the original finder.I Often quote to my better half the reasons for not disposing everything!........"I'd rather have something and not use it, than to need something and not have it?"

Astro Imp Posted January 18, 2015 Share Posted January 18, 2015 I'm in the camp to keep it so as to include it in any possible future sale. Link to comment Share on other sites More sharing options...

swamp thing Posted January 18, 2015 Share Posted January 18, 2015 Keep it to convert to a guide scope.The OP has a Dob. I would keep it. as others have said when you upgrade you won't want to sell the RACI finder with your scope. Link to comment Share on other sites More sharing options...

Sorry, didn't intend a thread hijack!A finder scope is a visual aid to point the scope in the right place.A guide scope is fitted with a camera and used to electronically control the mount to track the movement of a star and keep the scope accurately pointed for imaging purposes.

So the camera on the guider controls the mount? Ah no, just re-read it. So there must be a gizmo that links the guide scope to the, er, imaging scope/mount. Phew, so much to learn about AP. Which is why I guess I stick to manual & push-to visual Thanks for explaining! Link to comment Share on other sites More sharing options...
Kropster Posted January 19, 2015 Share Posted January 19, 2015 Yes. The guide camera is used to control the mount.... effectively following a star automatically.The imaging scope is entirely separate and just sits on the mount that is being guided.Think of guiding as being the driver of a bus..... and the imaging bit is the tourist taking photos out of the bus window. I have a QHY5-LII camera that connects to the mount guiding port, but still needs a computer connecting to the camera to do all the calculations.I think there may be or may have been some guide cameras that do it all for you.Somebody will know some names.Basically, somewhere in the guiding system you have a camera attached to a computer (which can be built into the camera) which then controls the mount based on what the camera image is doing.

SpoonyPizzas Posted January 20, 2015 Author Share Posted January 20, 2015 Many thanks all looks like I'll store it somewhere and not a problem hijacking my thread - I've learnt something from your question too so it's all good Link to comment Share on other sites More sharing options...
