      Well, I do have some nice scopes but I’ve been in the hobby this is my 31st year so I had lots of time to accumulate it plus a lot of the times I do buy used on the secondhand market and sometimes you can find them up to 50% off

      @@JoeJaguar I only got into this hobby in August 2023 and been trying to learn to use a telescope and a camera, neither of which I have ever owned before, as well as processing software, video recording and editing and You Tube channel maintenance.
      I hope to start posting videos myself in the next month or so. Sadly, I have a face for radio and a voice for print, so I do not expect to have as many subscribers as you.

      @@AnotherAmateurAstronomer well personally I don’t think I have a lot of subscribers. My first six months of making videos were just utterly horrible as I just had a camcorder and then, even after that videos started become slightly better but it took a long time. I think my videos are decent but they’re not professional quality.
      I’ve never taken a course in videography photography or anything like that, so it was slow process
      But I have seen channels in the US that have skyrocketed way past me, even though they started much longer after me
      Then somebody told me that USA RUclips is actually different than Canada RUclips and analytics works so much faster
      I’m not 100% sure how it works either but I have noticed my RUclips counterparts go 10 times faster than me
      I also have heard people contact me and my SEO is not ideal and could be better but of course I would have to pay for that which I don’t want to until I actually start making money
      And then, of course, some people pay for videos to be promotional and I don’t do that either so I guess it varies in a lot of different things
      Just recently, I’ve seen somebody on an Astro channel with only 10 videos, but have like 1300 subscribers. Meanwhile I have 237 videos with only slightly under 1800 hundred subscribers so I think I’m still kind of slow for some reason.

    I suspect that there's no getting around letting the entire thing acclimate. Even if it's a closed system, that big lens is going to see a huge temperature difference and cause convection on the outside.

      This is talked about many dozens of times on cloudy nights under the SCT forms people are saying it’s a done deal now for years,
      To me, my argument is exactly yours that I don’t think it’s been proven yet, but I’m cloudy nights. They say this is a dead deal that’s been proven for a dozen years now.
      On cloudy nights, so I guess I can’t start a thread, asking those who believe it to prove it

    You are the MAN for doing this and comparing scopes. Fantastic to know. Did not expect to be that bad with insulation, and it was good covered.

    • @JoeJaguar
      @JoeJaguar  Год назад +1

      I appreciate the comment looking back now. I just wished I would’ve done one thing and put my camera to the eyepiece with the insulation and with it off to show you guys.
      But to clarify, again, both images weren’t that great, but it was actually better without the insulation yes

    Fluid dynamics with heat dissipation is an extremly complicated matter. Predicting behaviour of air inside the telescope tube is very simalar to weather forecasts, and we all know that they are not always reliable. That means that only numerous practical experiments can give some answers, but also there may no good answers or predictability. Perhaps for certain temperature ranges there is some benefit from the insulation and for other temperatures it makes it only worse, only prolonging the temperation process.

      Thanks for all that I agree I got this information from cloudy nights and people talking about making scopes useable by insulating them so this is like the second video I’ve done if you’re not I have watched the previous video where I use the 6 inch outside. please go back a few weeks and you’ll see what I’m talking about.
      I am making one more video coming up
      cloudy nights forum says to use that aluminum stuff and since this is not an SCT I don’t know if that has any effect.
      I’m looking at it like how the MythBusters did it. I’m trying to do every angle until I figure this out.
      To me so far doesn’t look like it and a lot of the comments look like very low probability that it works but I want to give it the benefit of a doubt if people are saying it works. I want to try to prove it yes or no or maybe it’s a maybe
      Anyway, appreciate your comments. I’m not sure if I’ve seen your comments before but if not, hopefully I see you on other videos. Cheers.

    I need to test this thing out for a while, something tells me you haven’t used it enough to judge, you could take a scope out 12 times a year and not hit a good night, takes more than that.

    • @JoeJaguar
      @JoeJaguar  Год назад +1

      That could be true on this particular scope but on cloudy nights, we’re talking about insulation not sure if you’ve checked the SCT part and they always talk about insulating a telescope. You never have to worry about cool downtime.
      So on this particular test it was about that that if I insulated it, the image should be perfect right away and if I took it off, then would mean that the image should get worse because then it’s back to needing cool downtime
      I’m a bit weary about this theory and according to this video, the image got actually better after I took out the insulation, which is actually the reverse of the theory

    😢😢😢 the insulation is supposed to help throat at night help the temperature from the evening to the deep night and from the deep night maybe to the early morning it helps inflation of temperature not initial cooldown

      They clean as soon as you insulate you can start viewing extreme high powers right away. This is actually the third video that I did testing and I found it to be false and didn’t work.
      Thanks for confirming what I thought anyway
      I think the only real way to do it is to have three 8” scts one bear one with insulation and maybe one with a different kind of insulation and see if it actually helps any to what degree it is the only way to do it and I’ve never seen anybody do it this way

      @JoeJaguar  Год назад +1

      Thanks for the comment. And thanks for watching the video. Yeah, I understand about the temperature sometimes.
      I don’t mind so much because my backyard is just a few feet so I can go inside warm up and then go back out but I guess if you travel for your viewing then that makes it a lot harder
      That’s one of the reasons why I observe as much as I can from my backyard because it’s so convenient even though the light pollution is so extreme when I actually do get away for a week or a weekend that’s when I’ll do the more deeper stuff

  • @mikenofi281

    Insulating a telescope to avoid cool down will have the opposite effect. According to Newton’s Law of Cooling, the rate of change of temperature should be proportional to the difference between the temperature of the object and the ambient temperature. Insulating the telescope to reduce the temperature gradient will greatly slow the time to equilibrium. Instead of taking an hour to cool down, it may take several hours, depending on the effectiveness of the insulation. It is basic physics. Interestingly, much of the heat will initially radiate up and out through the objective lens (which can’t be insulated). This will raise havoc with the wavefront.

      I appreciate the info mike I have heard this on cloudy nights under the SCT forums where several people if not even more said this has been put to rest years ago when people have tested this I still have my doubts like you and a few others that’s why I’m testing this And according to this doesn’t seem like it worked
      So I’m trying to figure out if those people on cloudy nights actually have tested it or do they just think it does
      Now I have a feeling they might tell me well I didn’t use that real reflect lics it’s called that’s like a silver insulation and I’m not using an SCT or a Mac. Anyway, let’s see.

      I could probably believe that because the DZ is a new Scope. It could be very possible that they found the design now compared to 25 years ago, which gets a bit more contrast.
