Giro III deluxe
Posted 11 August 2010 - 07:09 AM
Will a counterweight be required if the head is used with a single telescope?
If this telescope and binos account for say 6 kg/ 12lb of weight.
Thanks in advance. John

For a FS-102, I did use a counterweight, YMMV.

Exactly the same for me: GIRO III is fantastic; take care that they mount it on the wooden Berlebach/Teleoptic tripod, if possible with the central pier: you loose the eyepiece tray but you gain in stability and ease of use.

Frank would you like to comment on the 10 lb comfort zone that Jim requires?
Could this be for instance closer to 12lb.
Jim, nice to see my FS102 on there already! John

First a pic of exactly the tripod I have:
Maybe I understood something slightly different under "central pier" and if so, please put it on the account of that English is not my mother tongue.
Then, I cannot give you absolute precise figures about the 10 lbs-12 lbs zone but:
- my 4.5" apo (focal 805mm) weights roughly 14 lbs without diagonal, finder and eyepeice: GIRO III is still usable without counterweight but I agree with Jim that it does not operate so smoothly and precisely: it can be done without counterweight, but it is far better with. And the longer the focal/tube length of the scope, the higher I would recommend the counterweight, except may be for catadioptrics which combine long focals and short tubes, but again, from a certain aperture on, the weight should be counterbalanced IMHO;
- my 3.5" ED doublet weights roughly 7-max. 8 lbs with diagonal and eyepiece. Absolutely no need for counterweight at my taste, but again, couterweight, that does not need be pulled to its most outer extend on the counterweight bar (position nearer to mount) improves smoothness.
I also note that Jim's GIRO III is mounted on a column: nice configuration, and probably also quite usable for longer newtonians (8-10" - f/5-6)?
You may also pay attention that the dovetail is fixed with the following system:
which at my sense is more convenient than the classic system with two screws like this one:
I hope this makes it more precise and I stay at disposal for any further queries.

When i want to be more light, i use my Davis and Sanford 400 tripod:
The Giro handles loads till 8 kg without cw. Also you can use a small refractor as cw:
In front the Giro with AP Traveler and Tak FS-60CB on Davis and Sanford tripod.
In background the Giro with C9.25 and Tak-Sky on Berlebach tripod.
Both are suited with an Argo Navis.

I have purchased these items from teleskop-express.de
and that is all I needed for a lightweight travel set up for two scopes, weight no more than 5 kg. and the Manfrotto kit ( 504HD head and 546BK tripod) seen in my earlier post came in at 6.3 kg, and was marginally dearer. So I am pretty contented. Shipping to the UK 38 euros all told for circa £500.
Thanks to all who participated. By the way, TS which is run by Patrick and is a very good company to do business with. This my second ocassion. John

With no counterweights:
The Giro will work, but not as smooth in AZ
The Unistar is much bulkier for travel and IMO not as smooth
The DM4 is the best option IMO (DiscMounts)
I have had the Giro, Unistar and now own a DM6. The DM6 is
very very nice (but expensive, but worth it).
Some more opinions for you to consider.

It seems that the Discmounts are very expensive, well imo, here in Europe. Not only the 6 but also the 4. The Giro can have for 250 euro or so. The DiscMount 4 was, when i was considering it, almost 1000 euro...thats without (!) the skycommander and includes import duties etc.
But lets point it clear: i do like the DiscMounts a lot!

owned was a very good mount. I really liked it. but I did use counterweights with it. my friend has a TEC140 refractor
on a Giro 2 on a wooden surveyor's tripod that works very

The Giro III TV weighted in at 2.9Kg the Berlebach tripod 2.9Kg as well both incorrectly stated on the web pages above. So all told 5.8Kg! This for travel weight. I am still waiting for details re:the sky commander, if there is a marriage then the mount will come close to 6Kg. More than I really wanted but there is a lot of stability in this package. And the fit and finish of these two items is highly commendable. Thanks for all posters help in this system. John

This is truly a great equipment: fit and finish looks premium and aesthetically, it is very elegant.
