  1. Thanks for the replies. Re balance I should have said that I am slightly east heavy Alan, yes I do dither, I'll have to check my settings and perhaps program a longer gap between subs.
  2. HI all recently ive had to throw out far too many subs due to star trails Due to my terrible skies I bought a 150 quattro to get faster imaging. However losing up to 30% of subs due to trailing isnt ideal , besides throwing away for the usual reasons. The following where taken on a belt modded heq5, 60mm guidescope, 150 quattro, asi 533. Guiding was sub 1". Ive locked everything down well to rule out flexure and balance is good. Trails dont seem to follow any pattern and occur at random any help much appreciated
  3. An old thread I know but was wondering if anyone has the 3mm extractor for sale as they are out of stock and I was wanting to do the mod. Thanks
  4. Thanks, I have both uv light and baader fluid, it's separating the two lens that bothers me. Wonder if anyone had disassembled an 80ed lens cell
  5. Hi all Really need help here. My old skywatcher 80ed has developed a couple of fungus branches on the inside of the rear cell! Any advice on how to get at this to clean it or should I send the whole cell off to a specialist. Thanks
  6. Ive been using the ts maxfied for a few years now and ive found no problems at all. No reflections and stars correct across the entire fov. Ive recommended this cc on numerous occasions escpecially when i see people mention problems with the Baader spacing and tilt. I use 56mm spacing with an Asi533 on a 130pds
  7. Have to agree Billy, living on the north coast of Northern Ireland I'm more or less in the same situation as you. Woeful weather, not just the winter either. In one whole year I've had the observatory roof open all night, twice! It's made worse when I see some guy in South England whinging about how bad their skies are 😡 Sometimes I do question if the hobby is worth it, living where we do.
  8. This is why I bought an az4, straight fit to an eq3, eq5, heq5 etc tripod
  9. Bubble nebula taken in August, rubbish weather since! Asi533 Ts Maxfield cc Optolong L-extreme
  10. Well, look what we have here. The dew shield screws off with effort and heat from a dew band. Thought most of these scopes did not have a threaded shield
  11. Sorry to appear a bit dopey but are you referring to the rubber washers in the focuser as they are still intact. Secondly you say that the lens cell is "jammed into the end of the tube" but surely it is threaded on and I can't see any way to adjust for cell being jammed in at an angle. Thanks for your help and quick replies Bryan
  12. "another popular cause of misalignment is the lens itself which is jammed into the end of the tube at an angle" I wonder if this is my problem? See previous post. Thanks
  13. Been having a nightmare with my 72ed too. top left and right of subs have eggy stars bottom left and right are fine. Originally had an OVL FF but i wasnt impressed so bought a Stellamira , things started to improve at 66mm spacing. When my scope arrived collimation was out by 7mm!! Having adjusted the focuser to tube alignment, with those awful grub screws, I really cant tell where tilt issues are coming from. Three different dslrs all tell the same story. As far as main lens cell is concerned my dew shield cannot be removed, when i try twisting it off, the entire lens cell starts to unscrew and its a newer version of the scope! The scope was bought new from Camarthen Cameras at the start of August, I'm very tempted to return it. I've wasted very few precious clear skies( North coast Northern ireland For goodness sake), trying to sort this out. Should have went for a WO 73 or similar
  14. REALLY interested to know your thoughts on this. Im very tempted. I currently have 2 130pds scopes and was thinking of selling one and getting one of these.Thanks
