To get multiple options - different people had been posting in the different threads. It worked. 🙂

Follow-up Q: Has the early version USB C-connector issue with the RPi-4 been fixed, or do I need to be selective about any USB cable I buy?

Thanks!

Thanks, both. Presumably the early version C-connector issue with the RPi-4 has been fixed?

Thanks, Pete.

A question for those of you with RPi-4: What are you using for a field power supply? My battery packs with USB won't go above 2.1A, and RPi-4 needs a minimum of 3A. 12V + buck converter, perhaps (and, if so, can someone recommend a reliable one?) TIA

Here's the deluxe version: height adjustable, and cranked for astronomer's-beerbelly-clearance :

...and you've reminded me that my lawn needs mowing. And it's only the first week of March!

Great report; thanks for sharing. Seems like you've hit a sweet spot with the 22x85.

Yes 🙂 - see http://binocularsky.com/binoc_hold.php

There'll be a review of the Monster in one of the Astro mags in the next couple of months. 🙂 I don't know, not having tried it with anything as heavy as that, but I suspect it would be safe with 7kg. As for the long moment arm, it's supplied with two counterweights and you can experiment with their positions on the CW arm to eliminate any resonance between the two sides and get maximum mutual damping - worked with a lighter bino. (For those that haven't seen the Monster, the weights don't have to be together, so you can maintain balance by moving one closer and one further away). As an alternative for bigger loads, if you can get hold of a 2nf hand (Larry has retired) Universal Astronomics T-Mount or Millennium mount, they hold a heck of a lot more. If you're looking for ideas for your build, the 10-Micron Leonardo is a really nice rigid P-mount, that incorporates some good ideas worth emulating.

It's a few tabs away for today's reading.... 🙂

The latest - 100th! - edition of the Binocular Sky Newsletter is ready. As well as the usual overview of DSOs, variable and double stars, this month we have: * A comet for binoculars * Asteroid Vesta * Appulse of Uranus and Venus * ... and a quiz to mark our century The night length is rapidly shrinking at the moment; I hope this helps you to make the most of it. To pick up your free copy, just head over to http://binocularsky.com and click on the Newsletter tab, where you can subscribe (also free, of course) to have it emailed each month, and get archived copies.

I don't use either, so I'm not the person to ask; sorry.

You can also find out more about what we bino users use and observers on the SGL bino forums (we don't bite 🙂 ) https://stargazerslounge.com/forum/133-discussions-binoculars/ https://stargazerslounge.com/forum/80-observing-with-binoculars/

+1 for the Heritage 130. I teach astronomy courses and it is one that I recommend as the nearest thing to an ideal "absolute beginners" scope. I also have one for my granddaughters to use when they visit.

These don't. The removable cap covers a screw that holds the hinge together. A Kaiser clamp and an Opticron hinge clamp both work fine.

They are both Kunming United Optics BA8s, but it is possible for different branders to specify some variations. However, they are unlikely to be massively different. If I didn't already have my (now venerable) Miyauchi Galaxy Bj100 (bespoke interchangeable eyepieces), I'd probably go for one of the APM ED APOs. A friend has the 100mm, and it's a cracking bit of kit (he uses sets of Televue eyepieces, but you could probably get away with lesser ones unless you're bumping the magnification right up - in which case, use a telescope, not a bino (IMNSVHO, of course 🙂) )

@mark81 In case it's of interest, there will be a review of the Orion-liveried version in one of the astro mags in May. (Sorry, can't say more at this stage.)

I keep a spreadsheet with the data of all the binocs I review or own, plus a few others. Those that are in your price range and go below 54.5 (I measure them, not just copy from vendors' specs)are: Vortex Raptor 6,5x32 (50) Opticron Adventurer T WP 10x50 (53) Opticron Adventurer T WP 8x42 (52.5) Frankly, at its current price of £79, that 10x50 Adventurer is a steal. My review of it is at http://binocularsky.com/binoc_reviews.php HTH

What Ian said! I know someone that has one, and it is quite simply beautiful. But, much as I'd like to, I can't justify it: I can see deeper with my Lunt 16x70/monopod-triggergrip combo which is less than half the price.

No comparison. At all. My review of the PRO version is here. Don't use a tripod; use a monopod and trigger-grip head (see here) - almost maintains the portability, and still much quicker to set up than just about any scope except a small Dob.
