using the new Edmund 8" f/5
Posted 24 October 2004 - 09:07 PM
Well I'm back after finally getting my summertime health problems under control. I took the fork mounted Edmund 8" f/5 to the Mid-Atlantic Star Party last weekend for "official" first light and was not disappointed with the view! The wide field views are amazing. They're so amazing, that I ended up purchasing my very first Nagler (22mm Type 4) from the fine folks at Camera Concepts. They had a great booth there. This eyepiece so impressed me that this past Friday I ordered a 12mm Type 4 Nagler so it'll (hopefully!) be here for Wednesday's lunar eclipse. I can just imagine the wide field view of the eclipse with these eyepieces on the f/5 scope.
I've also concluded that a red dot finder is essential with this (non-goto) scope. Back in January I got a Scopetronix red dot finder at BoBfest (another local astro gathering) and never used it till MASP on the f/5. Conclusion -- piece of junk. The red dot, even on the low setting (and there are only off, low, and high) washed out just about every star. I need something with a variable brightness red light and I've decided on the Rigel Systems QuickFinder. It comes with two bases and I can use it on my 90mm Mak too.
Any other eyepiece recommendations for this great scope?

You lucky dog, Glad to see you are using that scope now. I always thought as finders go, that the Red tubed RA finders were not bad. It should have a pretty good 9x40 RA finder on it. Anyway using those old mounts, you learned to read setting circles and star hop real quickly. But the setting circles are large enough that with the wide field of view you should be able to get anything into the eyepiece with just a rough polar alignment and the circles. Good luck. I'm still hoping to find an 8" red tube to go with my 6".
Also Re the eyepieces, you should have a 2" focuser on that if it is original. The secondary is large enough that you should be able to get some incredible views with the larger eyepieces.

How about some pictures of your most-rare treasure?

I also purchased the fork mounted Edmund 8" F/5 reflector in the second half of the seventies.
Is this telescope really such a most rare treasure?
I have a problem however with re-assembling the fork-mount. Can anyone please help me with a drawing that shows the exact position of those small parts in the fork-mount, like washers, etc.? Thanks a lot!

Personally, I think this scope is a treasure mostly for my own personal sentimental reasons. I know for sure that I've not seen many of them for sale over the years. Either people really like them and are not parting with them or there just aren't very many of them out there to begin with.

Let me start by saying that I'm Dutch/Flemish speaking and living in Europe (Belgium), so it's not easy for me to find all the right English names for those small parts.
I'm not talking about the big parts (tube, cradle, mount & legs) but about putting the small parts on the declination axis knob and on the RA motor drive back (washers, tension ring, etc.) back in their right places.
Edmund Optical itself directed me in an e-mail to this forum of specialists on the Edmund Telescopes for help.
I didn't use this telescope for many years now, but I also treasure a lot of memories using this Edmund telescope in the 70's and early 80's. If there are not many telescopes of this type around in the States, than mine may problably be one of the few (or perhaps even the only one) in Europe.
