Giro III deluxe new
      #3976303 - 08/11/10 08:09 AM

Comments please about the use of this head in single mode.
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

Under 10lbs, azimuth motions are okay. Over that amount, I prefer to use a counterweight. A counterweight makes tracking all the more smoother and puts less stress on the bearings, IMHO.

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

Hi,
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.

Hey this is good. Yes, I was going to be using a berlebach tripod but that appears to fix directly to the 3/8th bolt beneath! ie no central pier Frank!

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

Hi,

First a pic of exactly the tripod I have:
http://www.apm-telescopes.com/pro_info.php?id=64961
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:
http://www.apm-telescopes.com/prismenklemme-deluxe-mit-klemmschuh_proinfo_46142.html
which at my sense is more convenient than the classic system with two screws like this one:
http://www.apm-telescopes.com/prismenklemme_proinfo_94008.html

I hope this makes it more precise and I stay at disposal for any further queries.

Frank thanks I shall take a little more time to read around the english versions of these pages. More info is better. The decision is a travel setup and I do not want counterweights! that was so nice abot the Manfrotto 504HD head counterbalancing all built in.

The Universal Astronomics Unistar Deluxe may also be option, no cw's necessary with the altitude arm be so close to the azimuth.

The Berlebach's are great. A friend of my is using one.Me myself use a Baader hartholz stativ:
http://www.baader-planetarium.de/sektion/s05/s05.htm

When i want to be more light, i use my Davis and Sanford 400 tripod:
http://www.astro-physics.com/index.htm?products/products

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.

Jim and Traveller thanks for coming thru' with additional ideas and confirmation of such good products and some tolerance in the single use weight allowance.
I have purchased these items from teleskop-express.de

http://www.teleskop-express.de/shop/product_info.php/language/en/info/p4202_GiRo-III---Alt-Az-mount-for-up-to-18kgs---Twin-view-for-2-instru.html

and

http://www.teleskop-express.de/shop/product_info.php/language/de/info/p1207_.html

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

Hi
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.

Wes

Wes Hi. Discmounts - a bit late for me! However, this is a product that I forgot about. I came across the product only a few years ago so I thank you for reminding me. I think it is one great simple idea and I have contacted OPT for details re the Sky commander. This could be the next thing to 'energize' my solar activity and get me tracking. Thanks for the considerations. John

Wes,

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!

I use my heavy as a stock C11 C9.25 on a Giro 111. I use counterweights and Sokkia tripod. It handles the load with ease, I use up to 400X. I haven't used my Giro without counterweights but I have used my 20lb mak on my WO EZ with out them and it worked fine. The EZ is much less heavy duty than the Giro. David

Yes, that DM4 is very expensive for you. The Giro 2dlx I
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
well.

The two items arrived today into for some late sun.
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

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