    A poor man’s Mk5 binoviewer

    Key message: You can make Baader Glass Path Correctors work with a William Optics binoviewer. I like using my William Optics binoviewer for the wide field of view it gives, but I resent having to give up view width to a Barlow just to get it to focus (I have 1.6X, 2.0X and 2.6X Barlows for it). What I want is the widest possible view with edge-to-edge clarity using as much of my existing kit as possible. The 20.3 mm Clear Aperture of the WO BV limits the eyepieces you can use without vignetting. Before I invest in a new Maxbrite II or Mk 5 GrossSpendungsBinoViewer I want to investigate whether I can get the sort of widefield view the 24 mm Panoptics would give in these, using my William Optics binoviewer and 19 mm Panoptics (which I already have). Playing around with astronomy.tools’ field of view simulator indicates that the 24 mm eyepiece with a 1.6X Barlow is equivalent to a 19 mm eyepiece with a 1.25X Barlow, and the increased view gives to a useful amount of extra sky. So the hunt was on for a 1.25X Barlow. OK so Baader insist on calling it a Glass Path Corrector, but they make a version that fits inside their 2” T-2 nosepiece. And I already have that on my WO bino. RESULTS Disappointing, in so far as the binoviewer refused to come to focus on my 132 mm WO refractor even at 0 mm extension with the GPC fitted to the end of the binoviewer. However, the Baader website notes on the GPC indicate that if it is placed in front of the diagonal, rather than between the diagonal and binoviewer, you gain extra in-focus, so this is what I eventually tried. I want to retain the Amici prism diagonal because it gives a right-way-up, right-way-round image, just like binoculars do. I think this is one of the main reasons for using a binoviewer. My APM diagonal has an SCT thread on the scope end, and I had an SCT to T-2 adapter which more or less fits. The adapter reduces the clear aperture of the diagonal, but since I’m using 1¼” eyepieces anyway, that doesn’t matter. But it would mean allocating that diagonal to binoviewer use only. Can’t do that, so I’ll eventually need a special Amici prism diagonal just for the binoviewer. Baader make one, and I’d need it if I upgraded to a MaxBrite or Mk 5 anyway so the diagonal and GPC wouldn’t be wasted.

    Must admit I don’t use any extra processing on normal photos. Like them natural Each to his own methods. If you are happy with your results that is what matters

    Flowers make great topics to photograph Phil. What I would have done was remove the green leaves that are cutting accross the pretty flowers. I have often done this and actually if I remember I take a pair of little scissors with me in my rucksack. by just doing this it will make the photo fill less cluttered. As for processing I use Photoshop CS6 and use the shadow/highlight tool most often, and then add some unsharp mask to the image. Hope this helps.

    I snapped these at Mum's house yesterday. Is it just me or does everybody else process their non-astro photos, as I do? I used Curves in GIMP to emphasise the structure, then boosted the brightness and contrast.

    A Yorkshire joke!

    Bill and his wife Blanche go to the Yorkshire show every year, And every year Bill would say, " Blanche, I'd like to ride in that there 'elicopter " Blanche always replied, " I know Bill, but that 'elicopter ride is twenty quid, And twenty quid is twenty quid ! " One year Bill and Blanche went to the fair, and Bill said, " Blanche, I'm 75 years old. If I don't ride that there 'elicopter, I might never get another chance " To this, Blanche replied, " Bill that 'elicopter ride is twenty quid, and twenty quid is twenty quid " The pilot overheard the couple and said, " I'll make you a deal. I'll take the both of you for a ride. If you can stay quiet for the entire ride and don't say a word I won't charge you a penny ! But if you say one word it's twenty quid. " Bill and Blanche agreed and up they went. The pilot did all kinds of fancy maneuvers, but not a word was heard. He did his daredevil tricks over and over again, But still not a word... When they landed, the pilot turned to Bill and said, " By golly, I did everything I could to get you to yell out, but you didn't.. I'm impressed ! " Bill replied, " Well, to tell you t'truth I almost said summat when Blanche fell out, But tha' knows, twenty quid is twenty quid"

    Hi everyone - 3hrs integration and processed as a bi-colour image in Pixinsight. All the best! 🙂

    You're welcome. I originally used a pair of single polarised filters. I'd put one in the diagonal and one in the eyepiece. All I had to do was rotate the eyepiece to alter the transmission. This isn't so useful with a diagonal helical focuser. A couple of years ago I did a series of observations of Venus setting in twilight. With the paired polarisers I actually managed to see cloud detail. I told Reggie this and he used some Meade variable polarising device which achieved more or less the same thing. Except he managed to photograph it. Sunglasses could work too lol.

    Venus

    Great idea, thanks. With a DSLR, I'm not sure whether I can fit mine but I have used one with my Meade Electronic Eyepiece and have used one visually. It was a quick session before dinner and I couldn't be too long as I should have been helping in the kitchen! With a DSLR, I can control the exposure time. When I first started, I used sunglasses to see Venus and Jupiter.
  26. Well 1 week on from moving in to the new gaff I managed to try out my new skies last night. I saw that the forecast was for a good clear period so I went onto the balcony and swept the storm blown leaves and water from it late afternoon in preparation for an evening session. The water and leaves make footing treacherous at the best of time let alone in the dark and trying to contort in unusual positions at the eyepiece. I also made sure I put the rubber feet on the tripod to avoid puncturing the balcony flooring (EPDM not sure how thick but I wasnt taking chances) So I set up the ED80 Binoscope on the giro fitted with az circle and wixey with skysafari on my phone, so finding stuff would be easier. I used the 18.2mm Televue Delites because I just love the views 😀 First observation, the wind, crikey it was cold but I percy veered. The balcony is above the protection of the conifer hedge and it's exposed Second observation, EPDM covering for the balcony when wet is like ice, despite sweeping earlier it was treacherous so I had to be careful, I will be putting antislip on here in the near future so that will sort that. Third observation, our nearest neighbour, approx 400 yards away has a very sensitive outside light and its set to blast over everywhere in our direction, not a major problem at this distance, more of a mild irritation. OK so what did I see? The skies were as I had expected, pretty good, (like my old gaff 25 years ago). The storms and rain had washed the muck out of the atmosphere and the atmospherics were turbulent still but the skies were dark So the first object to view and test the darkness was M35, the companion cluster NGC2158 is my test for this and yep there it was easily seen, a lovely sight.. M37 was next and I always linger over this and trace the dark lanes between the stars, dint bother with 36 and 38. Venus showed it phase quite well in the 18.2mm eps Uranus was a blueish green dot M81 and 82, very nice, a bit of detail in 82 Owl Cluster, cracking as ever Eskimo nebula Double cluster, oh momma this was nice, colours, stars everywhere, fantastic, the Delites really do this justice M51 hmm, yes but nothing much just a smudge with a shape. M1 a small trapezium shape, surprisingly bright M31, 32 and 110 quite nice, I swapped to 30 mm and pulled the lot in one FOV for these. I messed around sweeping across the MW waiting for M42 to clear the tree tops then just drank in the vie. A wide fan shape with the trapezium twinkling towards the centre. I rested my eyes on this for ages until the cold and wind got to me but that was a nice sight. Looking forward to a few weeks time when I can get some of the objects below Orion. So, even though I was exhausted from the house move and sorting stuff over the past week getting out under a new clear sky did me the world of good. The balcony is going to be my visual obs station because its just too exposed but I have already earmarked a spot in the garden which, with a bit of prep will do nicely for imaging. No I dont have plans for an obs, I dont think I shall go down that route again.

    Do you use plane polarising filters? For visual I find they seriously reduce glare on Venus. I don't do AP but they're supposedly good for imaging Venus, sometimes revealing cloud detail. I suggested this to someone on another forum and he tried it and had this (link below) photo published. https://www.skyandtelescope.com/online-gallery/cloud-detail-on-venus-using-variable-polarizing-filter/

    "Shambolic old men in tweed jackets" was one of her more amusing one liners, when she described our astronomy fraternity back in the day when she first came on the scene. I don't think we have any 'shambolic old men in tweed jackets' at EMS......? 🤔 Or do we.....? 😄😉

    Venus

    Same set-up as Feb 11th. The phase has shrunk. I had some false colour, that shouldn't happen with a Mak but a bit of processing got rid of it and showed the phase properly.
