  1. I also have a TV-60 and think that it is a great little scope. I second the suggestion for: Panoptic 24mm, the Nagler 9mm and the 3-6mm Nagler zoom, which is what Al Nagler recommends on his website. The Vixen HRs are terrific eyepieces (have 3 of them) and to my eye they outperformed the Vixen SLVs and Delos eyepieces when barlowed with the superb Baader VIP barlow (which I consistently found to sharpen the views a bit). With a 6 and 5mm, the TV-60 does not deliver enough magnification power for planetary observations, therefore to me you will end up using the zoom at 4 and 3mm most of
  2. Why didn't you attach the wheelbarrow handles to the rocker box directly, instead of using an intermediate structure?
  3. Yeah, using a router for the first time is a kind of experience! Wood snow as you said and wild noise!
  4. No problem I checked Berlebach website. Mine is this one: https://www.berlebach.de/en/?bereich=details&id=242 With the extras: * Double Cable Clamps UNI (this is nice for extra safety, but I don't think it is needed - for my set up at least) * colour: Natural (the nutwood brown looks lovely too.. ) * Thread: 3/8" but I asked them to make the bolt protruding 15mm (done free of charge) * leg spread stop: Not the optional one, but I asked them to install this instead: https://www.berlebach.de/en/?bereich=details&id=170 My tripod was ordered
  5. Yes, my berlebach UNI19 has an extension column and works really well. In the UNI, the central column can be locked. I would also suggest to get the leg spreader (no innuendo was meant!). Berlebach can do it for you. They might install this slightly lower if you get a tripod with a central column, but this won't affect its stability. These are great tripods.
  6. Also my telegizmo didn't cost anywhere near 200 pounds, but it is massive for your telescope...
  7. In the end I decided to get plywood panels from https://www.slhardwoods.co.uk/ . Great customer service and very good sample. For the time being, one B/BB board (12mm thickness, 9 plies) and one BB/BB board (15mm thickness, 11 plies). I will glue boards to get more thickness for the rocker box. My order from Randy (Astrosystems) should arrive soon and truss attachments are already ready. So, it should not take me much time to make the UTA. Thank you, everyone, for your advice
  8. I've often wondered whether the hyperflex zoom is a clone of the Nikon zoom MC2. I have the MC1 version, which is 21-9mm and unbarlowed, it performs slightly better than the Vixen SLV I had, which to my eye, were on par with TV Delos, apart from fov and colour tone. For the latter, I preferred the SLV. A combo that I found to work really well is: low power / large fov ep, zoom, Barlow. I regularly use two of these combos: 1) 2" combo: 30mm APM UFF, Zeiss zoom 20-75x, Baader VIP Barlow 2) 1.25" combo: 24mm TV panoptic, Nikon MC1 13-30x, Baader Barlow 2.25x A good q
  9. Sad news. I have three of them and they are outstanding on both planets and double stars. They are also terrific for white light solar observing, although I do not remember the last time I observed a spot due to the low solar activity in these years. It is also a shame that they did not make a 5mm model. As far as I read, the design cannot be scaled to that focal length. In a desperate need for a 5mm, some time ago I bought a Fujiyama 5mm HD ortho. Clearly not as comfortable as the Vixen HR, but to my surprise I do not have any issue with its rather tight eye relief (I observe withou
  10. How many plies does your Marine and Birch plywood have?
  11. Thank you all guys, really helpful feedback. I will check out Jewsons and Travis Perkins as you suggested, now that the mirror cell for this 16" dob is completed. My plan is to have a wall thickness of 12mm or 15mm for both the UTA rings and mirror box. For an f4, I could probably go for 18mm and make it hyper sturdy! Kriege advises 5/8”, which is almost 16mm anyway.
  12. I'll check. Thanks for the info.
  13. I will need thicknesses of 1/2" and 1". So far, I found this source: https://www.slhardwoods.co.uk/
  14. Do you have any recommendations for a reliable supplier of high quality hardwood hardcore plywood in the UK (preferably)? Thanks
  15. Hi Mark, apart from losing ~1 mm in aperture, it seems that the mirror almost touches the internal walls of your mirror box. Even if it does not, I feel there is not enough distance to guarantee adequate air circulation around the mirror. The internal dimensions of the mirror box should be 1 inch larger on each side at least. Also, the baffle ring structure seems to be almost the size of the mirror. This can potentially cause warm air coming from the mirror to move right on the light path. A larger mirror box can allow you to build a more adequate lateral support than three strong si
  16. Regarding the giro mount, a few people enjoy attaching a second telescope on the other arm. Personally, I've tried that combination but it never allowed me to align the two telescopes properly so that they could be used at hight power. I do use the other arm to hold a finder though. This works very well also because it reduces weight on the focuser side of the main telescope. It also improves the balancing of the giro mount, even though the ayo2 is not really affected by the weight of the tak-100. With the finder, I can often leave a high power eyepiece (e.g. one of the Vixen HRs) a
  17. Time to time berlebach tripods appear in the classified, but I've never seen one with the central column. Another advantage of the central column if you observe sitting, is that there is no need to regulate the chair height, just the central column. If standing, it means no sore back or neck due to awkward positions.
  18. It is a great tripod in my opinion. I recommend to add the leg spreader. Berlebach can assemble this for you if you ask. I am very happy with it.
  19. Thanks for your feedback, Gerry. And yes I agree. To do so, I would have had to sand it first, which was even more work. On the other hand, I recently built a wood panel to cover the opening on the lower part of the mirror box. This mod has given positive results, although there is still a bit of boundary layer that can be blown away. For this I will study the use of a fan gently blowing on top of the mirror surface. Anyway, because the opening is semi-permanently closed, I painted this wood bar instead. Therefore the is no chance to get stray light from the rocker box. And to
  20. Thank you! It is getting there! The positive thing of all this process is a good learning curve. There are a few things I would like to build..
  21. Just returned from a session outside. Venus was superb, the best view I ever had. Faint white - grey patches were visible between 250x and 400x. Really good view! I then moved to the classic open cluster in Auriga, Gemini, Cancer, and eventually ended up to the bright galaxies in Leo. The new black paint certainly makes a difference. On Venus I believe the top of the mirror box now painted black also increased contrast, as the sky appeared noticeably darker than usual. Looking forward to use the new light shroud, which landed in Heathrow airport this morning!
  22. Mounted! Just re-collimated the focuser and secondary. Therefore, I collimated the focuser and primary axial alignments and now it's ready! Here are a few photos after painting:
  23. This past weekend I took care of the telescope coatings. Certain parts were minimally coated, whereas others (e.g. UTA, wheelbarrow handles) didn't seem to be coated at all. Also, the internal was gray / black. After ordering the same products used by David from Rustins, I applied 4 coats of clear lacquer to the outside and 4 coats of matt black to the inside. Now the telescope looks so robust and protected from any kind of humidity! The parts in the light path are really black now. Also, before doing this work I removed the "button" screws used for attaching the light shroud to the UTA
  24. Congratulations John! I tried it with the Tak tonight, but was only able to see an elongated shape with no clear split. This was at 215x and 308x. However, I managed to split Iota Leonis at 308x. It is a nice yellow-white pair with magnitudes of 4 and 11, respectively. The companion chases the main star very closely as the latter advances towards the eyepiece field stop.
