Focal Reducers

Posted By Peter Glus

Charles,

I have a C14 and the only thing that works is the Lumicon Giant Focal Reducer. This comes as a stand-alone and as the Giant Easy Guider (the only difference is that the guider has the side tube and prism). This provides two choices of reduction (via a moveable lens element).

Problem is -- these are only available on the used market, so you have to pick one up here. If you post a wanted ad, you could probably pick one up for 150 or so.

130mm APO Triplet or Mewlon 210 or Vixen VMC260L

Posted By Peter Glus

Paul,

My feedback (if I had to spend 3 - 4 grand on a visual set-up).

1. Get a non-alt az mount with tracking...you will need this for planets and lunar especially if you are visual. I would get a G-11 with "push-to" like argo-navis (In My HUMBLE Opinion....push to is superior to go-to and a whole lot cheaper). This will cost you 1500 on Astromart.

2. Get a used C9.25 for 1000, AND get a used 110 - 130ish fast doublet and mount them in tandem on the G11.

Now, you have nice planitary / lunar views and a good fast wide field, and you can sit down and enjoy while on a chair.

ALTERNATIVELY

1. Get that G11 and Argo Navis

2. Get an Intes Mak Newt, like the MN71. That does wide field, planets, and lunar very well. But you have to stand while viewing.


Ed Ting once said sitting comfortably adds 1 inch to your aperature....I agree with him and your visual viewing position should be factored in here.

And my 2 cents on those EPs for that fine setup....

For 1000 bucks, get

- the leica zoom (the less expensive one) ~400 used for lunar and planets
- the 22 T4 nagler for the wide field viewing
- some nice UHC filters for those nebula

Agreed. Kudos to Herb. All communities needs "police" to keep law and order, and they need to pay their "taxes" to use the infrastructure...then they will be safe.

Items purchased twice?

Posted By Peter Glus

Vixen NA140...I purchased this...hold on to your seats....four times. I keep thinking I cant deal with the CA and then everytime I get the "or equal" I miss the FOV and flattness.

It's Time For An Eyepiece Review

Posted By Peter Glus

Rod,

Dont ask me why, but I have a spare Leica Zoom (40 - 60 FOV). I would be willing to lend it to you for the EP comparison....as conventional wisdom says this zoom is "the standard" against which all others are tested.

C14 primary mirror

Posted By Peter Glus

Jim,

This is beyond the usual repair I think. If it is out of whack, that means that the epoxy they use to cement it down has failed in some way. My understanding also is that it is difficult to recement this and align it properly w/o the right tools or equipment.
