  1. Thanks for the info, Vlad. Very interesting I've got an ED100 that I cut down to use as a PST mod. I've been wondering for years whether it would be usable with a focal reducer as an f6 ish scope for visual use. Unfortunately that model reducer linked above is a little rich for my blood for what would be "fun" project.
  2. It's surprising from these pictures just how much difference in size the extra 7-8 mm in aperture makes from 120mm to 127mm for scopes of the same focal ratio
  3. I might finally get around to buying the 10mm and completing my set
  4. The "blue" is just the paint colour Skywatcher originally made the scope in. They've freshened up and rebadged their scopes by giving them a new lick of paint 2 or 3 times over the last 20 years or so without changing too much (anything!) optically
  5. No, mine is the older, blue model. I'm not sure but I'd guess the screw bolts on the rings could cope with an extra 3mm diameter
  6. The 140mm Skywatcher rings are a perfect fit on my blue 127mm Mak https://www.firstlightoptics.com/tube-rings/skywatcher-telescope-tube-rings.html
  7. Edit: just found the answer while reading through the full (and very informative/ thread 👍 That's a great read. Did you happen to measure the height of the primary baffle from the mirror or backplate? I stripped and measured my gold 180mm a couple of years ago (nowhere near as exhaustively as you have) and would be interested to see how that measurement compares as all the other optically important ones seem to match up
  8. I've had mine for 15 years or so now on an HEQ5 mount with no problems
  9. Please don't take this the wrong way, John but have you EVER bought a telescope that wasnt "noticeably better" than its Skywatcher equivalent? 🤣😜
  10. Although most popular 150mm achros are f8, f10 isn't particularly slow for a 6 inch refractor. You're going to see a fair bit of CA in that scope even if it's a well figured lens
  11. If you're observing in the UK then Jupiter and especially Saturn are placed too low for the Mak to really show it's stuff
  12. I've got to admit, Mark. I had a 8 inch LX90 SCT years ago and was never particularly impressed with the planetary views it put up
  13. I've found similar (on a smaller scale) when comparing my 7 inch Mak with my ED120 on the planets. Unless conditions are poor the Mak always shows more, I've never bought into that "a 4 - 5 inch apo I will show you all the detail you can see on most nights in the UK" line.
  14. I initially had similar trouble when I first used my binos. What worked for me was trying different eye positions/ distances and relaxing at the eyepieces. I know this advice is a bit vague and not terribly helpful, apologies!
