TV Powermate

Posted By Ron Bee
For visual use Dave, I'd look into the 2.5X Powermate, 2X or 3X Tele Vue Barlow if you wanna go this route. I've never been very fond of barlow but the 2X Tele Vue barlow I have is quite a performer. Otherwise, more eyepieces always help wink.

Tele Vue 85 Obsolete?

Posted By Ron Bee
I couldn't agree more with Evan on the color issue. The author did not state whether he had tried a different eyepiece and the color might simply be eyepiece lateral color ;-), a bothersome possibility that the author did not seem to consider. Another possibility is there was something wrong with the sample he used.

I own the TV-85 larger brother, the TV-102, and have looked through TV-85 on the Moon and there's simply no false color at all at low power and certainly not at 25x ;-).

As to whether the TV-85 is obsolete, I can't answer that. In my opinion, there'll be people who always look to a finely crafted instrument and of course with as fine an optics as can be for the design and will be happy to pay more for such an instrument.

"Upgrade" from 155 to 160

Posted By Ron Bee
Maybe because the person wants an air-space design now grin. Afterall, there's some distinct advantage in this design 8O.

Light Cup noted Mars Rover - really?

Posted By Ron Bee
Well, it looked like the dark side of the imaging force was indeed
giving my Light Cup a vision through the Force the night before ;-). It
appears the dust storm has now moved where the Opportunity Mars Rover is now
situated! Here's the image - courtesy of my trust old 4-inch tall TV-102 Light
Cup ;-).

Enjoy,

Dioptrix experiences anyone?

Posted By Ron Bee
Joe Heafner said:

Last week at the Mid Atlantic Star Party, I got a 35mm Panoptic and love it! I also noticed that the same vendor had some Dioptrix units on hand. I didn't know my astigmatism correction at the time but after I got home, I discovered that Tele Vue makes one precisely for my prescription. Can anyone comment on how well the Dioptrix works? I have several of the compatible eyepieces.

Joe

Hello there Joe,

You can see what some testers were saying.

I spent my day with Al at OPT a few months ago and while I found with my 0.25 astigmatism the Dioptrx didn't make much difference no me (no surprise), I heard many people who came by were saying oooh, aaah. You may just want to go back to the telescope store and ask to try one out. Al was using the eye test chart commonly found at the optometrist office ;-).

IC1396

Posted By Ron Bee
Hello there Inge,

You've tackled on of the RASC Deep Sky Challenge object!

My 4-inch TV-102 Light Cup showed me this object with difficulty because as you said, it's very large. My note said I used my lowest power eyepiece (40mm Pentax XL) at 22x. With the UHC, the sighting was uncertain until I dropped in the O-III. (NELM was 5.6).

Keep trying using low power and you should be able to bag it.

Best wishes to your hunt.

I got my $ back on the RCX, so now what do I buy?

Posted By Ron Bee
You're thinking along the line of the Tak FS102 much wisely, Luke ;-). I'd also look into the FSQ106 and the Tele Vue NP-101 too if I were you.

However, you may wish to think about getting as large aperture as you can. So the Tak TOA130 or the Tele Vue NP-127 may be a choice though you may have to up the ante on your budget ;-).

Best wishes to your quest.

I sent back my 10"RCX due to too many problems. So with my limited $$, what do I buy? I'm thinking G-11 or CGE and a TaK 102??? I don't want to deal with forks anymore and I primarily want to image with my 20D. What do you recommend, Roland? The refund is burning a hole in my pocket.

Help me to justify 4"

Posted By Ron Bee
Dmitri Kulginov said:

A thought of having a 4" achromat has been visiting my mind lately. What good can 4" refractor be along with C8 and ST80 - specifically for deep sky? Can it add anything that I don't already have?

Dmitri

Hello there Dmitri,

In my opinion, a 4-inch APO will have maxmimum flexibility that can go from very wide FOV to very high power viewing. But since you specify "specifically for deep sky" and achromat (assuming this is what you budget for), I'd look into a wider 4-inch such as the Orion 100mm f/6 achromat.

Starbeam Quick-Release?

Posted By Ron Bee
Aaron McNeely said:

Hi, I just obtained a Starbeam finder. I would like to install it with a quick-release bracket of some sort. Does TeleVue make these? They have one for the SolSearcher. Thanks.


I don't know this for sure Aaron but from disassembing my Starbeam and looking at other parts, I think you need Quick Release Bracket (QRB-1002). You then need the Dovetail QRD-1006). Now I speculate that the base (ie. the holding bracket) of the Starbeam can be screwed into the Dovetail and then the Quick-release finally mounted on the clamshell.

Best gives Tele Vue a call ;-).

Nagler Zooms

Posted By Ron Bee
I don't see Phil's comment as negative but pointing the fact. This is correct and has nothing to do with the optics of the eyepiece. As you zoom in, you're changing the exit pupil of the eyepiece (i.e. going toward smaller exit pupil as you zoom from 6mm to 3mm) and thereby letting less light in. It's no difference than setting the zoom at 6mm and then say take your eye off and set the zoom to 4mm and look again vs sliding in a 6mm eyepiece and then swapping in a 4mm eyepiece ;-).
