  • Alright, seeing the moons was harder than I remember with 10x50 Nikon AE. Handheld, about 80deg up. For a few moments, I could pick them out, but the shakes got too intense to see them again reliably. That’s with decent knowledge of what to expect. My memory is probably based on the one time I actually used my homebuilt parallelogram mount. Or maybe when jupiter was 30deg up and my elbows were on a railing


  • By split a gallilean moon, do you just mean see up to 4 moons separate from Jupiter? I’m pretty sure I can distinctly see them, at least with elbows on a railing or on some mount. I guess I’ll have to look tonight if it’s clear. I kinda only remember catching 3 at a time and not investigating further. I do have 20/15 vision so I guess that plays a role. Good point to remind me not everyone has my hawk eyes. I don’t catch much color though. Usually too small and washed out. It’ll have slight pink bands at best. I haven’t been able to note a crescent shape for venus, either. But I figure even cheap scopes can show my planets, so it hasn’t been my focus


  • +1 on binos. They’ve kept me happy because they fit in a backpack or carry-on luggage. I’m deep in light pollution, so viewing is best done with some travel. They have less magnification, but they’re as bright as a much more expensive telescope and there’s a certain value to having two eyes on the night sky.

    10x50 is where I landed. Probably the same weight as your 7x50. While yes, the 50(mm) describes the outer objective lens, the key thing is really the lens on the eye side. Divide the aperture by the mag and you find that exit pupil size. 50/10=5mm, which is about the size of a dilated adult eyeball pupil - and they get smaller as you age. I’m guessing you have a Celestron or similar astro bino which has some advantages for this hobby. I am surprised at the ~$40 price tag, so I no longer want to recommend against it. Where I WAS going was that 7x35s would likely give a similar image from a reputable manufacturer while saving a little weight and being more likely to be found at a garage sale. But who could say no to $40 new 7x50s? As long as OP avoids those 20x50 boating binos or 10x25 hunting binos, they’ll be in good shape. My 10x50s are closer to OP’s budget because I opted for Nikon Action Extremes to survive my beach spot, hikes, travel, drops, and any other mishaps alike. Things go bump in the night so rubber coating and waterproofing was worth it to me


  • NOx is not Nitrous Oxide and is not short for Nitrous Oxide. Nitrous Oxide is specifically N2O. NOx refers to both Nitric Oxide (NO) and Nitrogen Dioxide (NO2), both of which are far, far more damaging to health and atmosphere than N2O. NOx emissions are the reason diesel is generally nonexistent in US passenger vehicles - not even great mpg numbers have sufficiently-low NOx emissions.

    Even if it included N2O, using nomenclature with a variable like “NOx” and grouping it all together as one inert byproduct vastly underrepresents harm. Imagine if you referred to another group as “COx” but saying it’s relatively inert and easily detected by way of a burning lung sensation but feeds plants so it’s not all bad because Carbon Dioxide (CO2) has that effect. Carbon Monoxide (CO) is completely left out of that description and will silently kill you.

    Well, you see, the blood was warm when it was spilled. Unfortunately, because the customer was in the 3rd tier SuperSavings Freedom Unlimited* HSA Semi-Preferred SelectChoice Healthcare plan, all claims require a 24-hour waiting period after symptoms erupt to allow rebuttal from the primary physician. The blood was only cold after the grace period elapsed.

  • Yeah, there’s that little legitimate concern that gets washed into the conspiracy theory. It’s gotta be intentional. Proponents of weather alteration bans can find lengthy descriptions of TINY weather modification operations to fuel the idea that chemtrails are real, opponents roll their eyes because obviously chemtrails aren’t real and brush off the idea that a part might be true, so they don’t even engage with the proponents.
