Hi all,

A newbie here seeking your advise: I recently bought an excellent condition Nexstar 6SE here in Astromart (http://www.astromart.com/classifieds/details.asp?classified_id=553213) but was hit early on by the aperture fever so I went hunting for an 8" OTA to replace the 6SE OTA (I've read here that the 6SE and 8SE mounts are identical so my 6SE mount can handle an 8 OTA) but I came across an ebay item for a complete set almost mint Nexstar 8 (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290218549570) which was simply to good to pass up so I ended up buying that 'scope as well. Now I want to put the Nexstar 8 OTA on the 6SE mount and vice-versa, put the 6SE OTA onto the Nexstar 8 mount. The mount rails don't look the same to me, I've only seen pictures of both of them. Any suggestions? Thanks a lot! (I like the new features of the 6SE mount, like easier staralign, which I read is a step up from the older Nexstar 8 goto module, hence my desire for the swap.)

Regards,

Hernando

p.s. Strange as it may seem, I have yet to lay my hands on these two Celestrons (and terribly itching to do so); they are both in the USA right now waiting to be shipped to me here on the other side of the globe in Manila, Philippines; that is why I am asking advise on what are all the items I need to purchase (I have done so online for other items as well thru my Paypal account, with shipping address to my friend's place in San Diego, CA)so that I can have everything I need ready prior to the overseas shipment of my 2 'scopes. I wouldn't mind seconds, if there are any available on the net. Thanks.

To get the NS8 on the newer mount, all that will be needed is a Vixen compatible dovetail. The original NSes weren't designed for removing and replacing the tube, so you'll need an adapter called a "Ray's Bracket" if I recall.
