  1. Glad you have managed first light and are enjoying your scope.
  2. I found these instructions useful when collimating mine http://www.starrynights.us/Articles/Collimation.htm http://www.astrophoto.fr/collim.html
  3. Not sure this is the thread I was thinking of, but it does sound like a similar issue and there are some photos of the holder and adjustment mechanism, as well as how it can buckle. https://www.cloudynights.com/topic/465107-c8-collimation-at-limits/ I’m not suggesting you have a problem with yours, it might just be a case of loosening one of the others to allow you to tighten the one you need. Just be mindful that the screws are the only thing holding the secondary on, so only loosen one at a time and make sure you haven’t unscrewed it fully.
  4. When you say it doesn’t turn smoothly, is that just when tightening, or also when loosening? The secondary pivots around a central pivot point. If you overtighten the screws it is possible to buckle the pivot as it’s plastic. I have seen a thread with some pictures so will try and track it down. When I collimate my SCT, if the screw I need to tighten is already tight, I loosen the opposite screws slightly so that I can tighten the one I need to. I then nip them all back up tight after. I have read some instructions that say you should only ever tighten the screws but can’t see how that co
  5. @SpileI think that what you are suggesting would still fit within the StarGazine format and platform. Some of the ones I’ve seen have been more interactive during both the presentation and Q&A session. It’s just down to how you manage the session. When there is more of a presentation style session happening then you need to make it more formal to stop frequent interruptions, but the same tools could be used in a more open and interactive way and even with different compères. I don’t necessarily see a need to spawn a new series of programmes on a different platform, unless of course you are
  6. I echo the comments above, and it was probably a couple of early purchases from the for sale section that made the difference between me continuing with the hobby or not. Publicising the nature of the scams and educating people to the risks and how to exercise caution to minimise them is the best way forward in my mind, and there has been some useful information posted already on this and related threads. Maybe there should be a buying / selling tips sticky thread to help people avoid some of the common pitfalls and scams. Unlike eBay, you can pass on an offer if you feel the slighte
  7. There are regular StarGazine presentations, if that’s the sort of thing you were thinking off https://stargazerslounge.com/forum/295-stargazine/
  8. Congratulations on your new purchase, it looks to be a great scope. I am going through the same sort of dilemmas regarding my next scope. I’ll be interested in how you get on as this is one of the ones I am considering (final budget permitting).
  9. I have wondered whether the TS and Altair Astro scopes are the same, or whether there is a subtle difference. The TS Optics Photoline 102ED is listed as having an ED FPL-53 and Lanthanum doublet objective, whereas the Altair Astro Starwave 102 ED-R states FPL-53 but doesn’t mention Lanthanum in the mating element. Does anyone know whether the Altair Astro is using Lanthanum or not? The Tecnosky 102ED doesn’t mention Lanthanum either. Just to remove any possible confusion, the TS scope you link to in your original post (TS 102mm f/7 ED APO Refractor) is not the same as the TS Optics Ph
  10. This full package is still for sale however, I am prepared to sell the mount and tripod separately so have raised another advert to cover that. The OTA is not available separately at this time although I might consider selling it if the mount and tripod should sell.
