    I have struggled to see the pup (Sirius B) even after years of trying. I will try again when they are better placed this coming winter. Thanks Tsula.

      I should have mentioned that when I did see the Pup it was fleeting. I do believe I got lucky with a moment of excellent seeing. It makes all the difference. Good luck next winter. Be patient!

    Very cool, Tsula. And with an 80mm refractor, no less! Can't wait for some clear skies to try it myself.

      @tsulasbigadventures  9 месяцев назад

      Thanks, Greg. I could have made it much easier on myself by just pulling out the 8" SCT instead of that tiny little refractor. I don't know what got into me to even try such a difficult thing. I wish you clear skies soon.

      @@tsulasbigadventures Since when don't you like a challenge, Tsula! 😀 The 8" SCT would have been too easy. Actually, we might have some clear skies for a bit tomorrow and maybe even Sunday. I'm not getting too excited yet. I also want to take a 'baseline' of T Coronae Borealis before it goes nova so if I catch it I can see a before and after. Only problem is it doesn't clear my horizon until about 10:30 each night through April. But, who knows when it's going to blow! It'll be interesting to see, though. (Worth a video?!)

      @@gregerianne3880 It's raining all weekend here but I'm hoping it will clear up Sunday. So, here's hoping for clear skies for both of us! I have been watching T Coronae pretty consistently but like you my view to the east is also blocked and I can't see Corona Borealis until very late unless I go out to my secret spot. I might go out there if it clears up. I have video of Corona Borealis but not specifically T Coronae. Since it's only magnitude 10 I'm not sure it would look like much as a single star. Is that what you meant about a 'baseline?" I definitely want to capture it if it suddenly brightens. I think getting pictures of single stars is hard and getting pictures of double stars is very hard. Have you tried that?

      @@tsulasbigadventures Ugh, hope it clears for you, Tsula. Yes, I just want to grab a long LRGB exposure (maybe 2-3 min) of T Coronae with a telescope now before it goes nova (if it hasn't already) so I have a reference for later. I'm hoping to take an exposure framed the same way each time I'm able to go out to image other things. 🤞

      @@gregerianne3880 Two or three minutes! Well, T Coronae is a faint star (as far as I know it has not gone nova yet) but for a double star that would be completely blown out, I think. I think you have to limit the exposures to about 1/3 second but like I said I have never been able to get a decent photo of a double star.

    Sirius is a good boy and so is his little pup. 🌟🐶🤩 But I've always thought of Rigel as Orion's knee, not his foot. Anyway, the collective group - the two dogs, Orion, and Taurus with his red eye and tilted horns - is certainly the sky's most impressive asterism.

      I consulted my star names bible What Star Is That (uk publication 1972) which gives the Arabic meanings of star names and for Rigel it describes 'the left leg of the giant'. Incidently Betelgeuse is described as the armpit!

      @@starsnstuff842 I guess I was wrong about Rigel. I thought it was his foot. Someone else commented that it was his knee. I only know a little bit of Arabic but perhaps it's like the Spanish word for leg which many Spanish speaking people in California will use to refer to the knee, the foot, and other pieces of the leg. But I have never heard that Betelgeuse is the armpit. I always thought it was Arabic for shoulder. But I'm not expert on star names. Do you recommend that book?

      Splitting Sirius requires a lot of lucky seeing and incredible patience. I must have stared at it for an hour waiting for the perfect seeing conditions and for the Pup to pop into view. Hmmm. M57? I have to get back to my log book in Montana to see if I have notes about seeing the central star of M57. It seems like I saw the central star with my 6" Refractor but I have to check my notes to be sure.

  • @lornaz1975
    @lornaz1975 9 месяцев назад

    Awesome! You saw it! In the picture you drew at 10:30 which direction was the star drifting? Reason I ask is that I "think" I saw it but it was in two different places in relation to the drift of the star which you know that is impossible so I don't know what I saw. Was the pup trailing behind Sirius or to the side? In one of my observations (well actually two) it was to the side but the other it was trailing behind Sirius. I had to use averted vision in every case.

    • @tsulasbigadventures
      @tsulasbigadventures  9 месяцев назад

      It was to the side. The reason I felt certain that it was the Pup was because it was NE as in the diagram and seemed to be 11 arc seconds away when I compared it to the distance of Rigel B from Rigel A which was also very difficult to split with such a small telescope. I wish I had had my 3mm eyepiece with me and that would have made it much easier for the Pup. What aperture telescope are you using to split Sirius?

      @@tsulasbigadventures Awesome! from what you said what I saw those two times would have been to the northeast of Sirius as well using the direction of its drift as an indicator of direction. I was using an Vixen 81s II and a Tele Vue 2x barlow and a Japanese 6mm ortho. Very very difficult to see. It sort of popped in and out in my averted vision.

    I've tried and failed to see the Pup for over 40 years using Newtonians of 6",8",12" and 16" aperture.
    The trouble is from my site in Central Scotland at 56N Sirius's maximum elevation is only 17 degrees so seeing is nearly always bad.
    At times I think I may of glimpsed the Pup but I don't tick any object off until I'm 100% certain to of seen it.
    Next year I'll try out your sticky tape trick!

    • @tsulasbigadventures
      @tsulasbigadventures  9 месяцев назад

      I know what you mean. I went to Fairbanks, Alaska (64 degrees latitude) in January and Sirius barely skimmed the horizon all night long. I think it would be hard to see it there but in this video I was able to split Sirius from my home in the San Francisco Bay Area which is only 37 degrees latitude. So Sirius was fairly high in the sky. Good luck next time.
