mount for "biggies"? Helios 25x100's.

No doubt it's on here someplace......

But , I just got my Helios Q4 25x100's ,and a Hama heavy-duty tripod . The 'pod is rated at up to 5kilos of payload , but it seems a bit overwhelmed by the sheer weight of these monsters . Do-able ,but not really confidence - inspiring . Can't help dreading that expensive "crash" . I could be wrong , but why take a chance . It only cost me 26 of your Earth pounds , anyway . What I wondered , was if anyone had any experience of a couple of things I was pondering .

1- I have an EQ 5 pro ,with a nice set of legs - sturdy , just the way I likes 'em ! Is there any adaptor/attachment widget to use the 'pod or even the whole EQ 5 kit 'n' kaboodle with these bins?

2- what about one of those super-duper parall-o-gram jobbies ? Any of 'em rated at 5 kilos plus? Anyone used one , or have one to sell ?

I know I may have offended the sensitivities-or should that be , sensibilities - of the grammar-police by hyphenating the "P" word , but I've been subjected to American car advertising for too long . "Speed-o-meter" , "Skid-King-Self-Locking-Dual-Fade-Brakes" . That kind 'o thing .

It may even be an option to build something myself , if anyone would like to share their wondrous inventions .

Incidentally , the bins are good stuff ,I managed some great DSO cops , from a dark site , admittedly , with a good few nebula catches , tho' I know not what they were , just pot luck . With a good mount , these bins would still be a "Grab 'n' Go" option for holidays and the like .

Any tips , folks? All input accepted with grovelling gratitude !

It's time to spill the beans , not spill the bins !!

A photo/video tripod needs to have a load rating of at least double the weight of your binocular just to make it tolerable. They just aren't designed for a load with its centre of mass so far from the altitude bearing axis, and the resultant turning moment that you get at high elevations.

I have a UA T-mount (heavy duty P-mount) that I use with 6.5kg binoculars. Love it!

Lots of mounting ideas here, including links to plans for DIY P-mounts (that's the usual abbreviation :laugh: ) - and piccies of my T-mount. Also, Michael Wilkinson, who posts on these forums, has plans for a P-mount that goes onto a photo tripod.

Thanks ,B-Sky !

Been looking for P-mounts ,most affordable ones seem to be out of production or otherwise unavailable . I have been using the photopod wothout any arm-based mounting jiggery-pokery ,just the little wedgie/dovetail plate that came with it , but I found that the bins could , with a bit of an effort , at least , be pulled up and off the 'pod head . Hardly confidence-inspiring . I'll take a gander at the links you suggest , and have already had a trawl thru' the Binocular Sky site , but it needs further research . I came across some commercially available plans for $15 or so , but now I'll be beggared if I can find 'em again !

The quest continues.

The current sky at night mag has started a DIY wooden tripod and p mount build, its in several parts, this month is the tripod. Looks quite nice.

Have just started to gather the materials together for have a bash at it.

I'd have a go at building a P-mount , not sure I'd like a wooden one , tho' . I think a metal one would be best for me , and if it can fix to the leg section of my EQ - 5 , that would be great . Anyone know the threadform of the securing bolt that holds the EQ - 5 head to the 'pod ? It would save buying a surveying 'pod , or making legs , methinks .

I've only just started stargazing but realized on my first night with my 20*80's that i needed a good mount to get good views. i wandered around a few jumble sales and found a battered theodolite stand for £20. plenty of wd40 got it apart. A good sand down, a touch of wood filler, hammerite paint for the metal, sadolin for the wood and plenty of grease when putting back together. looks brand new.

for the p mount a £27 sheet of ply, a £9 sheet of 3mm ptfe, a bag of bolts and wingnuts, repair washers, wood brackets all for about £25. A second hand set of dumbells courtesy of ebay. Only tools used were a jigsaw, drill and adjustable spanner. Started at 9am Saturday and finished 9pm. Packed it in the car and went straight out to test it. Worked like a dream. Great views on deep sky objects.

No plans were used. Just built it straight out of my head. I'm no DIY expert, if i can do this anyone can.

Would highly recommend just diving in and having a bash

Can we see pics of the build friedeggs? I too am thinking of a theodolite stand but  the centre section link from that to p mount has me puzzled and need to see pic for ideas, I can get a theodolite stand off ebay cheap enough even seen one at a car boot sale for a tenner a while back, sounds the better option as I am no craftsman by a long shot!
