I only just found this thread, Jules...
First off congrats on your little project. It sounds to me that with the chip blackened (and perhaps the lens edges too) you are going to really enjoy that scope - and obviously arleady are, even with the damage.
The HEQ5 Syntrek is a great mount. I'm glad I got mine last year, originally for my 6" f8 achro, but it also serves splendidly with all my OTA's (even the 60mm f13 Swift!)
Reading up on some of the stories told here, I may as well share the fact that a couple of years ago I owned a selection of ED refractors, including a lovely tasty 90mm f6.6 triplet from Telescope Service in Germany that was a superb instrument, and probably a better performer than I ever needed.
Fast forward to now, and I currently own a big medium f-ratio achro, a semi-classic 90mm f14.4 achro, a classic 60mm f13 achro, and have just sold a rare 80mm f12.5 achro, as well as previously, a 80mm f11 achro.
My tastes changed round about the time I acquired the 6" f8 and put so much time and effort into it. It showed how good an achro could be, and revealed that colour correction is not the be all and end all of a good telescope.
Hence the long pointy tubes I now own.
My enjoyment of the 90mm especially is immeasurable, and I'm constantly surprised by the quality of the 60mm Swift as well.
Inspired by these scopes, I'm currently assembling a Carton 60mm f16.7 from parts supplied by Richard at Skylight, and am really looking forward to seeing how well a self-built scope with relatively easily obtained, yet high quality, parts, can perform...!
Clear skies to all!
