  1. The TTS Panther has a payload of 22kg. Fully motor driven. https://trackthestars.com/ The Mammoth holds even more... Tom
  2. Love mine, had it a good number of years now. Great on planets and moon. Takes magnification up to 180-200x fine, although I tend to stay below 160x under my light polluted, unsteady skies. As your acquaintance infers, struggles somewhat on dso's, but then 4" is 4" - dark skies help. Doesn't weigh much so sits beautifully on EQ5/AZ4 mounts and upwards. Focuser is servicable but needs tweaking now and then. Sharp, contrasty views? Yes. Great detail on dso's? No - they are there, but just. Over the years I've had a 150mm F5 newtonian, a 200mm F6 newtonian, a 150mm achromat and a 127mm mak. The 100ED is the only one I've kept. It is what it is, but what it does it does very, very well. My purely subjective view, of course! Tom
  3. The one I use comes with a CD that has the driver. Worked straight out of the box. One thing though - you may have to change the COM port setting. If you're not sure how let me know. Tom.
  4. I use this: https://www.amazon.co.uk/gp/product/B00QUZY4WO/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 Works with W10. Tom
  5. In fairness, the author of the linked article repeatedly points out that those exceptional views occured in rare, fleeting moments of (almost) perfect seeing. The key words here are 'rare' and 'fleeting', which probably is a good summation of seeing in the UK, and rather demonstrative of average conditions. Everything is subjective, of course. That's part of what makes life fun! Tom
  6. Light pollution prevents much deep sky observing from my location, so planets and brighter Messier objects are my thing. I have a 100ED and recently, after a year of gathering side by side observing experience, moved a Skyliner 200 dob on to a better home. The reason? To me, the refractor gives consistently better views of the planets. I'll go one further. My 100ED gives consistently better views than my 6" achromat too. Tom
  7. This does already exist, to a degree. Look up the Track The Stars Panther mount - an alt az mount with goto that is suitable for imaging. The third axis is implemented using a mechanism to rotate the tube. Tom
  8. Windows 10 being the last version of Windows was announced a couple of years ago: https://www.forbes.com/sites/antonyleather/2015/05/08/windows-10-to-be-last-version-of-windows/#64b42098713a Be interesting to see where it heads...
  9. Thanks for the suggestion. I had a go this afternoon - managed a small improvement but there is still slippage. Time permitting I'll have another go tomorrow. Regards, Tom
  10. Thanks Olly. I think it's that the weight is too much for the clutches. No matter how hard they are tightened there is slippage and I can't see any obvious way to fix this. Regards, Tom
  11. Absolutely. Indeed, I've found that the dampening times are acceptable when using the 6" refractor on the AVX. I was simply making the point that I've found that the mount won't track reliably with this load - the goto's start off okay but worsen significantly as the evening goes on, no matter how carefully balanced the scope is and how accurately the mount is initially aligned. I don't experience this issue with a lighter load. Unless I'm doing something wrong, which is always a possibility . We could argue that accurate goto's are not really essential, but they are one if the reasons why I bought the mount in the first place. Regards, Tom
  12. As much as I love my AVX with my 100ED, it's just not coping with my 12kg 6" frac. As hard as I tighten the clutches it still slips and I lose goto alignment. A shame as up until now it's been a fantastic mount and I hate to post a negative comment. Do post and let us know how you get on. Regards, Tom.
  13. Hi all, Just to extend the original question a little...I recently picked up an old Meade AR6 achromat. It wasn't something I was particularly after, but opportunity arose and hey ho it's in my shed. I have an AVX mount which my ED100 sits on beautifully, but it struggles with the Meade - the dec clutch slips and I lose goto alignment pretty quickly. I've been pondering upgrading to an NEQ6, but have been put off by the size and weight. The Meade plus diagonal/rings etc. is coming in weight-wise at around 12kg. If I recall, the AZ EQ5 handles 15kg. Is this enough tolerance or should I be looking at the NEQ6. Of course with the AZ I've the added bonus of alt-az observing. What are people's thoughts? Cheers, Tom
  14. With a bit of practice it's easy enough to keep objects within view. Tom
  15. I had a Portamount - not good with a 6" newtonian. My AZ4 handles a greater payload. Tom
  16. Hi, is 1-2 hours not enough? Can't you then just rewind the rotator and go again? Please forgive my ignorance I too saw it at Astrofest. It is a lovely, elegant mount, but, yes, pricey. Thanks, Tom
  17. Probably because it's been around longer and been used by more people. I've used both and there really is very little between them. Am perfectly happy with my AVX but equally can understand why others would promote the HEQ5. Tom.
  18. It certainly does help! However, FLO sell a SkyWatcher reticle eyepiece that's a lot cheaper.
  19. Hi, I used to have one of these scopes and did mount it on an AZ4. You can use it with this mount, however it's not ideal. Lots of vibration when focusing, which can make getting that sharp focus point somewhat tricky. I can't recommend an alternative as I've only used the AZ4, but I'd look for something that carries a more substantial payload. Tom
  20. The holes don't have to be big or particularly deep, just enough to stop the tripod feet slipping out of them. Like Jimjam I find it a real time saver!
  21. Hi all, Apologies for resurrecting this, but last night was the first chance I've had since to use the scope. This time I used a 20mm Meade 4000, a BST 12mm and a Pentax XF 8.5mm. The view was better - lovely on the moon - and the previous problem of the focusing either the inner or outer seemed to have stopped. However, now I seem to have the centre and top half of the field of view in focus, but the bottom third (or so) out of focus. This was especially noticeable on the moon. Is this down to collimation? I had the same problem with all eyepieces I tried. Thanks in advance! Tom.
