Helios Fieldmaster vs Naturesport - both 8x40WA
BinocularSky replied to Space Kat's topic in Discussions - Binoculars
Binoculars are very personal things, it seems. I used to have a Naturesport (10x50) - just didn't get on with it at all (I preferred the Fieldmaster), And I'm not a great fan of the Nikon Aculon either. But other people love both. I've also heard that some people like dew-and-debris magnets (aka mirror-mounts) as well ๐ . -
Opticron Adventurer II WP 12x50 or 10x42 Binoculars?
BinocularSky replied to Krum40's topic in Discussions - Binoculars
12x50 is a bit too much to hand-hold, and also less bright than the 10x50. -
Opticron Adventurer II WP 12x50 or 10x42 Binoculars?
BinocularSky replied to Krum40's topic in Discussions - Binoculars
Ah, that could be because the binocular I so highly recommend is the Opticron Adventurer T WP 10x50, not the II WP ๐. It's temporarily out of stock at FLO (link in the review to which you hyperlinked), but if you go to that page, they currently have an "open box" one at reduced price. Absolute snip! -

Filters for Visual Astronomy
BinocularSky replied to FLO's topic in Sponsor Announcements and Offers
On your blurb for #29 (Dark Red) you could add: * Use as an alternative to a Moon filter to enhance contrast (especially near Full Moon) and improve sharpness. Almost nobody believes this until they try it ๐ - essentially, a #29 is a narrow band-pass filter, so it almost totally eliminates the effects of chromatic aberration anywhere in the optical chain. -
Replacement for my old binos
BinocularSky replied to xvariablestarx's topic in Discussions - Binoculars
In your price range there are exactly two 10x50s I'd be confident in recommending: Opticron Adventurer or Olympus DPS1. -
The Binocular Sky Newsletter, November 2020
BinocularSky replied to BinocularSky's topic in Observing - with Binoculars
Binos aren't really the instrument of choice for planets, but they do at least enable you to detect Uranus and Neptune, and some of the asteroids when they get bright. And, as @happy-kat implied, you don't need much to see the Jupiter's Galilean satellites, or Titan for that matter. I've even seen Callisto with these freebie (at Astrofest a few years ago) cardboard and plastic 2(?)x25 opera glasses: -
If you want to find out why people near Chippenham are particularly favoured next week, you'll need to see the latest edition of the Binocular Sky Newsletter ๐. As well as the usual overview of DSOs, variable and double stars, this month we have: Two grazing lunar occultations Four Mira stars near maximum Ice giants in the evening sky A meteor shower with bright persistent trains Elan Valley Dark Sky Day (online) I hope this helps you, especially those of you under lockdown, to enjoy these long November nights with your binoculars or small telescopes.

David Hinds Ltd - End of an era!
BinocularSky replied to FLO's topic in Sponsor Announcements and Offers
Sad to read this. Adam, if you're reading this thread, all the very best for the future! -
+1 for a parallelogram - the one in my avatar is the AstroDevices one with 20x80s; it wouldn't struggle with 25x100s. Only problem is that it's too easy to doze off during a long session, they are so comfortable to use ๐

Helios Apollo 15x70 (Unboxing & First Light
BinocularSky replied to Damo636's topic in Discussions - Binoculars
I did the same (OK, melted a hole with the soldering iron). Then I discovered that the binos were just as steady with the monopod going down the side of the lounger - that's when I realised that monopods don't need to be vertical to work. ๐ -
Re @ollypenrice's "nodding" the scope: a similar technique that I have found to be useful with a scope of a mounted binocular is to give it a sharp tap with my fingertips or gloved knuckles while using averted vision - the shiver can reveal things that were hitherto invisible - and they remain visible.

@deniamnet I'm a bit late to the party here... ๐ The whole Porro/roof thing is oft-misunderstood. In general (ie not always) at any given price-point, a Porro will have better optical quality than a roof, largely due to the difference in precision with which the prisms must be made. The Vortex Crossfire is one off those that is pretty close to the "not always" category, but I wouldn't get the 12x - very difficult to hand-hold steadily. The 10x50 is much better - brighter, and wider field of view. I've been very impressed with Vortex binoculars (and not just because of their tramsferrable lifetime guarantee) I reviewed it (in a comparison of six different 10x50s around the same price) for Sky at Night mag a couple of years ago; this is what I wrote: I think you're wise to pass on the Skymasters (the Skymaster Pro, though are very much better). Also mentioned above are the Nikon Action Extreme 10x50 and the Opricron Adventurer T WP. My review of the Adventurer has just gone live on AstroGear Today: https://astrogeartoday.com/review-opticron-adventurer-t-wp-10x50-binoculars/ and the Nikons were part of the same comparison review as the Vortex: I hope that helps: Bottom line is that you'd likely be happy with any of these.

Binocular collimation using the Sun!
BinocularSky replied to markse68's topic in Discussions - Binoculars
Thanks, Bill - yes, we're all well. I've just come out of retirement (yes, in my 8th decade! ๐ ) and accepted a post as Dark Skies Advisor to the local International Dark Sky Reserve. Been volunteering for ages, but it's good to be useful! Keep well, my friend. -
Binocular collimation using the Sun!
BinocularSky replied to markse68's topic in Discussions - Binoculars
Hey, @WJC - good to see you on board here! (I missed your posts where you posted pages from your books, or I'd have cottoned on sooner). -
That's exactly it - it's not so much an "object" as what you describe. Same here.

Green Laser Pointer on 20x80 Binoculars
BinocularSky replied to bond19's topic in Discussions - Binoculars
Celestron do a RDF rail that clips onto the central bar for their Skymaster Pro series. If you do go the GLP route, probably the best way is a weaver or picatinny rail and a GLP gunsight. (Not exactly sure how to fit the rail to the bar, though - but you can get them with all sorts of barrel adaptors.) -

I got a dozen Opticron AdventurerT WP 8x42 for outreach (when I could do it!) - ideal for 8-yr olds. My review of the 10x50 version is here - the 8x42 is of identical quality.

Great news. This is one reason I chose Opticron for my dozen hand-holdable outreach binoculars. -
