Hello,

 

I want to get into auto-guiding and was looking around at the bazillion options when I realized I have an ASI290 and a stock 9x50 finder scope from a Celestron EdgeHD8 I could probably make do with, and give it try without spending any real money. smile.gif

 

1. I assume I'd remove the nose piece from the ASI290, and the eyepiece from the finderscope since that's where the threads are. Is that correct?

 

2. With both pieces removed, the specs for the ASI says the camera threads are M42 Female and for the finderscope is (waiting to hear from Celestron on his) so I just need a male to male M42 to XXX adapter? Would that work just camera/adapter/finderscope?

 

3. Am I forgetting something? My mount and camera both have ST-4 ports so that should be good, right?

 

Thanks!

Does the finderscope support a 1.25" eyepiece? If so, you can just remove the EP and insert the camera. However you may have problem in focusing. Instead of getting adapters, extenders etc., why not just buy a $79 Orion 50mm guidescope where the 290 will happily slide in, and save yourself the experimentation while retaining both finderscope and guidescope?

No, I have to remove the eyepiece of the Finderscope. And yes, I was worried about focusing. BUT experimenting can be fun when cheap lol.gif  And yes if the adapter is over 25 bucks I'll probably just get the Orion.
