Televue Panoramic: a good idea? new
      #3626444 - 02/15/10 03:06 PM

Hello mount-specialists,

I bought recently a 8cm WO refractor and I'm looking for a "grab-and-go"-mount. I can buy a second hand Panoramic-mount (250 euro) for less than the half of the new price (600 euro). Or should I better invest in an other Alt-Az-mount (AZ4, Versago, Porta, Voyager,...)?

Thanks for your kind advice.

Persoanlly, for a small refractor, i would avoid ANY alt-az mount nowadays, when low profile stepper motor EQs are readily available. I will never understand the popularity of the alt-az mounts. Even more perplexing to me are the price tag of many of them, with TV being a main offender.

To the OP, I have no experience with the TV mount you allude to but, IMHO for a small refractor such as you are talking about, a good alt-az mount is just the thing for grab 'n go use. I've never heard anything bad about the Televue mount (other than perhaps some issues with objects at zenith) so you probably can't go too far wrong.

As to the above poster, you are certainly entitled to your opinion but realize that there are many of us who value the light weight, ease of setup and simplicity of use of a good alt-az mount.

In MY opinion, the only reason for putting up with the increased weight and complexity of an EQ mount is if tracking is desired.

Ken, thanks for the reaction.

MorningStar, thanks for your opinion, but I will go for an A/A-mount... I know, some guys just won't listen to good advice

Are there no TV-mount users here around? Or what are you using as A/A-mount?

I'am satisfied with the TV-85 on a Telepod head. Balance is the key withg these type setups for smooth panning. A key component for this type of setup is the clamshell ring on the TV-85 which allows easy balance adjustment on the altitude axis. The tension knobs on the altitude arms also help, but should be snug at best.

If the WO ota has rings that allow for moving the ota forward or back for balance, then the Panoramic mount should work out fine.

Also be aware of the hole spacing on the Panoramic(Telepod) cradle in regards to mounting the WO ota which may involve doing some modifications if using a dovetail bar. Also, there is not much space on the cradle to mount certain dovetail saddles.

You may want to look at the AT Voyager mount which would not have as much balance issues in the altitude axis and will or should accept the built in dovetail bar(if it comes with one).

In my experience an Explore Scientific 80 Triplet on a Vixen Porta Mount is a very solid combination. The adjustable friction on the Porta eliminates balance issues when changing EPs and is overridden with a light push for point and view. The slow motion controls are smooth, long flex handles are recommended.

The whole bundle was quite manageable in weight - I could walk the fully assembled kit out the door with little difficulty. If the Porta has a weakness it is the aluminum tripod. Swapping the legs for wood will increase the dampening considerably. With a fast 80 you're not often going to get the kind of magnification where this would even begin to be an issue. I liked the Porta head so much I've built a heavy duty wood tripod for it that I intend to use with a TV 102.

I considered a Gibraltar but won't have an A/A mount without slow motion controls. The Quarter Hitch looks nicely overbuilt but is quite pricey. With TV mounts you always hear people talking about sliding the OTA back and forth to get balance.
