  1. Good studies again Mike, last night was the first opportunity here for a few evenings due to cloud banks. Observing from home, I had to wait until Jupiter was edging towards the South. The seeing did stabilized intermittently, those two large barges are still prominent in the NEB and the South Temperate Belt was very defined, interesting watching Callisto approach.
  2. Yeah that's a very poor do Calv, do you know why the mirror needed that much attention? Looking forward to the wk-end reports. At the end of the day 12" manual flex-tube with a moonlite focuser is an excellent performer. As Dave has indicated, many go for the duel speed, I went with a single speed moonlite based on cost and weight which is also very smooth.
  3. There was an OOUK VX10 with ultra grade mirrors for sale recently on ABS, do not know if it is still listed and you would need to purchase separately the dob base, trunnion blocks. The Hilux, high reflectivity coatings will compete with slightly larger aperture with standard coatings. I considered this scope myself a few years ago when considering my first dob - which became a 12" Flextube, a good option though requiring some upgrades and mods, if I was ever to downsize I would still like one.
  4. Unless I missed something, the programme seemed to almost celebrate the extreme light source emitted through expanding mega cities as an indication to the success of human civilisation. In the round the issues raised were informative though much that was covered is established common awareness.
  5. Yep looking forward to it, it's going to be interesting, not least for highlighting the growing extent of global light pollution.
  6. I had for a season a TeleVue Planetary filter, in use the colour rendition would vary between a shocking salmon pink to a more aesthetically pleasing ochre tone. Some planetary features did appear to be enhanced through contrast, such as within the South Temperate Belt. I do not recall if refined detailing such as white ovals benefitted and there is the opinion by dedicated planetary observers that filtered use on Jupiter will diminish and reduce visually finer detailing. When they are apparent, steady seeing and high power is the best combination for revealing white ovals and as is often mentioned the more you look the more you see, which becomes particularly relevant for catching those periods of stable seeing conditions.
  7. The stubborn particle was removed with a blast of compressed air and thanks to Telescope House for an assessment and rectifying this. I had noticed what I thought was a fragment that would not dislodge with either an air blower or soft sable brush and the illusion was that a small defect had lodged in-between the lens elements. The particular sharp curvature nature of this glass element design, had both enhanced to magnify and create this distorted illusion of an internal particle. TH had expressed and as is very well known that the Tele Vue quality control is exceptional. In retrospect since I was situated on my allotment, it just might have been air born pollen. Here are a couple of pictures and I look forward to the next opportunity to engage with this excellent eyepiece.
  8. Here is some further detail for observing the Veil Initially a UHC would be fine and then if you were able to obtain an OIII in time that would become an advantage. A Low power, larger exit pupil is compensated when applied with an OIII, H-beta or UHC filter when fully dark adapted and under a good dark sky.
  9. That is a good achievement Piero, cleanly splitting Izar with your TV60mm and a good account of that eyepiece. Actually I read your account just as I was about to go out and also took a look at Izar. This was with my 8" dob, so therefore there were some diffraction spikes to contend with, now I have an eyepiece capable of 120X I will try with my TV76 sometime. So it was 11.45 before Jupiter approaching the meridian, cleared the chimney top. Much surface activity again and I was able to explore this at 200x, since the sky was quite clean after passing showers earlier on. I can still see those large barges (or are they festoons) in the NEB and dark mottling in the SEB, also hints of white ovals, as it began to appear the GRS was quite impressive, I could make out the hollow, this was around 1.15am and just before Jupiter would start to sink out of view behind my shed.
  10. Yep I reckoned, good luck for the weekend.
  11. Just curious about the 24" Mike, is this to be a collective dob mob project or instigated by a dob mob member, expect that we will all get to learn in due course ?
  12. Hi Gordon, yes it is this one Berlebach 372 Report, which is superb for the porta mount and for lighter refractors. There is plenty of height with this model and I have been standing recently, which was applicable last weekend when I was sharing and entertaining family members with the views. The extended height is also useful if used at home as I have quite high walls. I also purchased a Berlebach tripod carry bag, which I can shoulder whilst carrying the scope bag (with eyepieces and rigel) and mount bag on a walk to my allotment space. I do leave the tray behind if walking anywhere. I can understand why Shane, it was very comfortable and engaging, very good contrast, it would have been interesting to have had the 3mm on hand to try out, though completely content to keep with this for high power. The 4mm does feel optimum with this scope Stu. I commented on there being a small static black spot visible, noticeable with either eye. Very recently received, I examined the eyepiece this morning outside in better light and there is what appears to be a chip on one of the inside glass elements. With a magnifier it looks a bit like a kind of air bubble void of any coatings. Anyhow regardless and this is unusual for a new TeleVue I will arrange to return and request a replacement on Tuesday.
  13. Interesting thanks, I was observing until approx 11.20 and the GRS was coming round on the disc. I am accustomed to observing barge features with my 8" scope and I am still gaining familiarity in what is observably achievable with my 3" scope (which is a surprising amount so far) and using up to 120X. Is a bit of a conundrum and may well have involved both simultaneously barge and festoon activity.
  14. Saturday 15th and I distinctly saw two dark areas on the NEB, which I initially deduced as being barges, yet I was using my 76mm refractor and barges are small features and I felt not entirely convinced that the aperture that I was using would pull them out. Could they be a facet of festoons, as I believe that there is some prominence in two large dark areas currently in this vicinity and for which may have some association with the GRS in the SEB?
  15. I got an opportunity to use my new 4mm DeLite with my TeleVue 76 this evening. Setting up on my allotment, the sky was a little hazy and I began with my dependable Pentax 5mm XW. After a short period and with Jupiter gaining in elevation I changed to the 4mm DeLite. Similar to a Delos in that you can adjust the eyepiece barrel for the most suitable eye placement. The image snapped into focus and I was immediately impressed. At 120X and with a 0.6mm exit pupil, I could detect a little more fine detail, such as the South Temperate belt and the polar regions created a pleasing tonal contrast, there were also a couple of barges, particularly apparent in the NEB. The eyepiece is highly engaging with 20mm eye relief and immersive, the field stop creating a pleasant window with a 62 degree field of view that did not feel at all as being confined. There was no kidney beaning effect, though I could detect a small black spot which is probably due to my own eyesight perhaps. Observing Jupiter and the moons as it drifted across was eased by subtle adjustments with the slow mo controls of the porta mount. The session ended due to a cold North West breeze and I look forward to using this for lunar observing.
