  1. Thanks Geof. Good feedback on the ADC especially with Saturn. Those red/blue fringes are partly what made me take a punt on a coloured filter this year with the planets so low. I haven’t noticed the fringe before, but it’s quite obvious now even when the planet is "high" directly in the south. The filters do tighten the view in suppressing the colour, but I wonder if the impact would be different when the planets are higher.
  2. Lots of factors involved when you’re trying to see things at the limits of your physiology, your kit and the conditions. Glad you had some success with the moon filter. Twilight viewing can show some surprising detail that seems to get tougher as the sky darkens - and is free! . Of all the variables, I think the filters are not near to the top of the list though, so I’d recommend don’t be in too much of a rush to buy (nebula filters are a different story... ). A good quality high power eyepiece would be on my shopping list before coloured filters for sure. Plus collimation, seeing, patience, etc
  3. Slim pickings right now with the late summer nights and the planets low. I can’t see Jupiter or Saturn from home, but was keen to try to get at least one decent session on Jupiter this season so headed out to a site with a low southern horizon and reasonable seeing across the grassy fields. Nice views in twilight, including the Great Red Spot and Io approaching/merging into the disk. The seeing was bad initially (and I almost packed up), but improved fairly quickly as the evening cooled, becoming ok but not brilliant. With a few seasons under my belt now, it’s nice to see the evolution of the features on Jupiter. Not to claim any real level of expertise mind; A few seasons more needed to learn the names too! The equatorial zone is darker/yellower and seems wider than I recall from previous years. The northern and southern belts seemed thinner. The southern belt has previously had a broad swathe of turbulence in the wake of the GRS, whereas last night it was squeezed very thin by the bright zone to the south. The GRS had a notably dark southern boundary. I don’t know if these are fleeting or long term changes but still nice to notice things evolve. In terms of the filters, these were a recent edition to the kit. I was in two minds, given that they seem to divide opinion, but in the end I took a punt. A blue filter brought out knotted texture in the north equatorial belt more prominently. An orange filter confirmed three large festoons and made the bright southern zone particularly obvious. Equally, some features were lost with the filters, so quite feature/filter specific rather than overall better/worse. I felt these effects were noticeable within a few seconds at the eyepieces and didn’t require scrutiny or a drawn out game of Spot-the-Difference. Not to say the effect was dramatic though. With the filters removed, the improved features were still there, but less often and less easily - but then the worsened features got better, so take your pick! Overall, I’m content with their first light and feel that they contributed towards a good session. But, with little surprise, by far the most important aspect was patience - filters or otherwise - especially with the wobbly seeing. Saturn was terrible, but the scope was practically horizontal peering through the soup. Better views to come though!
  4. Really enjoyed reading your report. Glad you had some good views. Takes some effort staying up to observe at this time of year!
  5. The baader fluid and a lens cloth is a good idea. I’d add that I use an air blower first to blow off dust etc, then a fine haired lens brush to gently remove any further dust etc, given that such dust could be abrasive if wiped across the surface with a cloth.
  6. Solar white light viewing is like is box of chocolates as Forest Gump might have said if he was connoisseur of this sort of thing. The big AR approaching the edge of the disk but still putting on a good show. The Wilson effect visible. A thin bright border on the surface surrounding the penumbra. Long swirls of bright faculae trailing the AR in it’s wake, though maybe this is just an impression with no corresponding physics behind it. Two small new spots have emerged and still a way from the edge too. Maybe they’ll turn into something worthwhile? Grab a look if you can!
  7. Nice one Paz. Enjoyed reading that. Similar views here, with clouds coming and going, but they cleared just in time to see some of the brighter stars disappear behind the dark leading edge of the moon. Although I was expecting it, it was still a surprise to see them vanish instantly rather than fade out. I thought it was a really demanding test of the eyepiece with the almost blindingly bright moon and faint stars. My wide ES82 14mm and 8.8mm showed a more glare with fewer stars visible than my simpler cheaper eyepieces. How did you find the Delos?
  8. Wowzers! Just had the little 72mm out before the sun dipped below the rooftops. First daylight outing for the binoviewer, which slotted nicely into the Lunt wedge. Two cheap as chips stock Skywatcher 25mm Super MA eyepieces, giving about 50x in the bino with the 2.6x corrector, with the combo easily beating a more exotic eyepiece in cyclops mode. Bags of contrast and texture all across the solar surface, only intermittently glimpsed in mono. There’s a big juicy spot out there too at the mo. Subtle shading on the edge of the penumbra. Three tiny pores detected too. Really impressed with the bino on solar! Bino or not though, it’s good to see some solar action in white light after so long. Worth a look if you can.
  9. Great sketches. That’s a smashing observation of M81. I’m not sure I’ve ever seen it as anything other than a featureless blob, even under decent skies and patient study. Insipiring stuff though - one to go back to (again!). ? Not to dismiss the M82 observation either. It doesn’t look much different to your sketch through my 10"... ?
  10. Sounds a great session. Lots of sights I would really love to see! Hopefully one day!
  11. Just a brief report of a number of double stars observed. Lovely moonless night and the bite of winter seems to have gone. A real treat after the recent cloud-fest. Canes Venatici 2 CVn. Fabulous. Almost a Spring Albireo. Σ1632. Great view of this wide pair, 1 bright, 1 pale. The Silver Needle Galaxy in the field too! Σ1645. Faint and lonely pair. α CVn. Stunning! 16-17 CVn. Very wide. Couldn’t detect the mag 9 third member. Σ261. Even close pair. Easier at high power. Σ1755. Somewhat uneven. 25 CVn. Couldn’t detect the secondary. S 654. Very wide equal orange pair (unrelated) with a fainter third member. Leo Minor 7 LMi. Wide uneven triple in the eyepiece. 11 LMi. Failed to detect the very faint companion. Σ1374. Uneven, close pair. Lovely contrast. ΟΣΣ104. Wide even pair. White and pale orange. Σ1432. Wide. 1 bright, 1 faint. 42 LMi. Wide triangle with pleasant colour. After this, a quick view of Double Cluster before packing up. It absolutely popped with stars! Hope that everybody else got some good views too.
  12. Nice one Neil. SGL is a great place and all the more so with your posts. Keep ‘em coming. For March 2021, are we looking at 6 scopes, 32 eyepieces and 20 filters then? ?
  13. Really like this topic. If "useful" means useful for getting you excited in seeing and learning what’s up there, the minimum aperture is your eyes and anything above that is a bonus! ? I used 50mm binos for months before getting a scope and they revealed loads. It was this aperture that gave me my ongoing enthusiasm for the hobby. The step up from the naked eye was utterly enormous. As others say, this is dependent on the skies by at least somewhat dark. If the binos had been a 50mm scope with potential for high mag, then even better!
  14. While I love the view in my frac, I reckon I’d go for a large sensible sized dob too. It just pulls in so many more things than a smaller scope. Currently got a 10" in this role which might or might not change one day, but I think it’ll always boil down to what’s the largest sized dob I could quickly load into the car and drive somewhere dark.
  15. Great report. I can relate to it with a galaxy session last year during which I got pretty excited at a possible discovery! In case you’ve not spotted it already, there’s a DSS viewer within Sky Safari itself that’s useful for this - I use it a lot for comfirming marginal observations in general too. Really useful feature.
