Upgraded finder for an 8SE?
      #6502443 - 05/02/14 02:23 PM

Hi all. I have an 8SE and the little red dot finder is *BLEEP* out on me. What do you guys recommend as a replacement? I had a Telrad on my old dob, but it seems a little too clunky for this scope. I'd like to spend less than $50 on whatever it is.

There's not a lot out there for under $50. Even a replacement RDF like the one you had will run you $30-$40 depending on where you buy it. I use a GLP (green laser pointer) and 9x50 RACI combination and love it. But those two, along with mounting hardware, will set you back around $150.

If I had to recommend just one finder that is close to your price range and will work well on the 8SE, I'd suggest the Orion 6x30 RACI for $59:

The 6x30 gives you a wider field than the 9x50 so it's easier to acquire your target initially, but still provides a bit of magnification and more light grasp than a non-magnifying finder. Plus, the right-angle diagonal makes it a lot more comfortable to use.

Unfortunately, on top of the cost of the finder, you'll need to replace Celestron's proprietary finder shoe with a more standard Synta/Orion style shoe which will cost you another $25. However, if you do that, you'll then be able to use most standard finders in the future.

Dan,
Oooops! Dan I think that the shoe from Orion goes for $17.00 and some change, at least that's what I remember when I bought mine.

Hi Fred:

You are correct! I was looking at the prices at ScopeStuff which includes 'free' shipping. Not sure what the Orion price is with shipping, but the purchase price is $17.99.

I just checked Agena Astro and it looks like they have a mounting bracket for $13.95 with free shipping.

Is this the mounting bracket that will fit the 8SE?

Also, this 6x30 RACI doesn't use batteries, right? Is it as easy to align with this thing as with a Telrad?

Yes that looks like it BUT Agena Astro has free shipping and their service is great.

Hi mostly,

The one in your link says explicitly in its description that it is NOT intended for use with schmidt-cassegrain telescopes ... although I'm not sure why.

I would go with the one Fred mentioned from Agena:
http://agenaastro.com/agena-sct-dovetail-mounting-base-finder-bracket.html

The 6x30 finder does not need power because it is not illuminated. It should be as easy to align as a telrad, and probably more accurate because of the magnification factor.

I still can't decide between a Telrad and this 6x30 RACI finder.
Anyone tried both on an 8se?

Yes, I had both on the scope at the same time and decided to get rid of the Telrad for a number of reasons. First, it puts your head in an awkward position for viewing through it, just like the red dot finder. Second, in my opinion it just looks clunky and out of place on an elegant scope like the SE. Third, it dews up faster than the corrector on an SCT.

And finally, I don't think it offers any advantage on a goto scope. It's designed primarily for star hopping and is excellent at that job. But with the 8SE, you never need to star hop. You only need the finder for the alignment process. A small, comfortable to use, RACI does the job fine. And since the RACI provides some magnification, it also makes the star appear brighter, easier to see, and more accurate to align on.

Heck at one point I had a Telrad, a laser plus a RACI finder on my scope all at the same time for about 3-4 months...

I removed the telrad because I make so little use it...BUT I could also have removed the RACI finder for the same reason...The reason I left it on the scope is that while I do not use it as a finder I do it it as a small wide field Telescope in its own right

For alignment I use my Laser ..

BTW... I love the look of a Telrad (pure function..industrial design..

Man that thing is crazy! Aren't you worried about all the weight?

Sounds like the small RACI is the way to go. Thanks for the input guys.

Been using that scope for 8 or 9 years now the way it is set up... IT has never let me down...accurate GoTos & Tracking (has kept the ENTIRE full moon within the fOV of a regular 25 mm eyepiece for HOURS...

I have about 7 pounds on top (from memory because we have had this discussion before

I also use all three finders on my 8se - a Telrad, a 9x50 RACI, and a GLP. I use the Telrad during alignment 60% of the time, and the RACI 30% of the time. The GLP is mainly just for fun. No issues whatsoever with the added weight or balance.

Holy *BLEEP* what is that platform your hand control is sitting on. I need that. Stupid thing is always falling off and bouncing around everywhere.

Hi mostly:

Not sure about that one that Oliver uses, but here's the one I have:

Mine is the 'Wing Thing' from S&S Optika in Colorado. It works fine but is not a great fit in the handset cradle. I would probably buy the JMI if I had it to do over again. Nice to have.

Hi M.E.S,

I made my own from sheet alumimum. It is attached to the rotating part of the mount using velcro. I also find the hand set more comfortable to use from the position I have it, as apposed to the position of the "wing thing". ( I tried mine on a bracket mounted there)
The stripped tape is an aid to locating it in the dark.

Regards. Peter.

I also use the original Wing Thing (fr4om S & S Optica) and it fits fine in the cavity of my 8i
I actually like it a "little" better then I do the one JMI sells
