  1. I didn’t manage to see the rille tonight either. I was using an 8” SCT, although I was having to view between the gaps of some high branches. It did seem as though there was a noticeable drop in contrast whenever even a couple of small branches entered into the FOV. Thanks for the heads up though as it has given me something to look out for on future nights, as I often stop for a brief look at the Alpine Valley area when viewing the moon.
  2. I’ve been able to clearly see the quadrangle tonight. I haven’t yet managed to see the nearby kite shape feature that was also visible last time around.
  3. How many eyepieces are included? The set on FLO contains 5 + a barlow, but only 4 are shown in the pictures above. Looks like it might be the 13mm that’s missing from the pictures.
  4. I only used a cloth for the final polish, once all the dirt was off. I used plain Kleenex tissues for applying the fluid. The Baader fluid feels a little sticky when wet so initially I dab the surface rather than wipe in order to pick any dirt straight off the lens. I then use a fresh Kleenex with some more fluid to clean it normally. I use the blower between each stage.
  5. I bought a bottle of Zeiss Lens Cleaning Spray (sold and fulfilled by Amazon so shouldn’t be fake), which states it’s suitable for all optical surfaces, including cameras. However, I have found that it leaves a streaky residue on the binoculars and eyepieces I’ve used it on. In some cases I then had to use another product to remove the streaks. Not sure if it’s due to coated lenses. Works great on spectacles, phone screens etc, without any residue. Maybe the wipes are a different formula. I’ve just bought some Baader Optical fluid and while that leaves some very faint residue marks, these
  6. So, possibly not where the X was on the map, but the feature next to it. Fortunately I did spend quite some time looking at that area too
  7. @Stu your second image shows what I thought was Barkers Quadrangle with a prominent line leading from it. I think that matches the kite shape that @mikeDnight mentions also. Tim
  8. Thanks @paulastro. I’ve enjoyed looking for the unusual features you have highlighted over the last couple of nights. It’s got me out observing on at least one night I wouldn’t have otherwise tried, and I’ve seen some new features that I probably wouldn’t have ever known about otherwise. Also thanks to everyone else who has chipped in with maps, diagrams, and other noteworthy features nearby. Tim
  9. Just posting a short review of my recent experience dealing with Altair Astro. Ian at Altair Astro was very prompt and helpful in responding to my initial questions. Some of the responses being sent late in the evening. He was also very quick to resolve an issue resulting from some damage caused in transit. I would definitely deal with them again. Tim
  10. 7 months on from the OP and I’m wondering if there have been any signs of reduced quality in recent batches of equipment? From what I’ve observed on this forum, it seems as though the manufacturers have managed to maintain quality controls, despite the high demand, as I haven’t noticed an increase in issues being reported, but would be interested in what other people think.
  11. By finder screw, I was meaning the screw that you used to mount the bracket. I was assuming that you used one of the mounting points and screws that are typically used hold a finder bracket, or mounting plate in place.
  12. Glad you managed to get it cleaned back up, but where did the filed aluminium come from and how did it actually get inside the tube? If you didn’t need to drill any new holes then I assume it got in through the finder screw hole somehow. Were there filings in the bracket hole that got pushed inside when putting the screw back in?
  13. I think it’s also called the golden handle.
  14. Glad you have managed first light and are enjoying your scope.
  15. I found these instructions useful when collimating mine http://www.starrynights.us/Articles/Collimation.htm http://www.astrophoto.fr/collim.html
