  1. Unfortunately, That's what I've already tried, it seems it was screwed in rather to enthusiastically in the factory. I'll have to try heat/gold/lube. At least I know I'm not trying something futile now!
  2. The screw that sticks out of the tube rings, I think it's for mounting a camera. Has anyone been able to remove it? It looks like it should just unscrew, but I've tried and so far no luck.
  3. I got one from FLO a couple of weeks ago, there's just about a 10day or so delay before delivery.
  4. Thanks very much, I'll have a read about the Optolong filter
  5. Hello everyone! I've just bought a 130PDS from FLO, there's going to be a little delay before it's delivered due to the ongoing "situation" I've also ordered a Baader MPPC III and a 2" SW Light Pollution Filter (https://www.firstlightoptics.com/light-pollution-reduction/liht-pollution-filter.html) I now wonder if I should have bought a different filter. I'll be using a Sony A5000 (APS-C sensor) and I'm in a rather inconveniently illuminated area. In truth I just searched for LPFs and then bought the cheapest...which is probably a less then ideal selection method. Would I be better off going with an Optolong UHC Light Pollution Filter(https://www.firstlightoptics.com/light-pollution-reduction-imaging/optolong-uhc-light-pollution-filter.html) or Explore Scientific CLS Nebula Filter (https://www.firstlightoptics.com/light-pollution-reduction-imaging/explore-scientific-cls-nebula-filter-1-25-2-inch.html) instead? (I've read about the first 30pages of this thread, informative and very impressive images! I'll carry on reading, but I thought it was best to just ask )
  6. It's pushing its limits, but there are quite a few people in the EQ3 imaging and 130PDS imaging threads that are using the EQ3 and 130PDS. So I think that's the way I will go, which is quite a surprise to me Thank you all for the help and information!
  7. I have an EQ3-2 Pro, it's imaging weight limit is 5kg. Which I believe is insufficient for the 130PDS. I'd had a good look through the 130PDS imaging thread a few days ago and it otherwise looks ideal. *edit* I was just Googling to see what a suitable mount for the 130PDS was, only to find that it's frequently sold with the EQ3 Pro! So it looks like I've dismissed it unnecessarily? It looks like the 130PDS might be the better choice as I'd then be able to spend the rest of the budget on other things I should really have.
  8. (I currently have the Sky-Watcher Evostar 90, at 900mm long it's F10) Thanks for the images, yes there's certainly a difference, which is very inconvenient! I'll have to look into any alternative choices and then have a good long think.
  9. I've been using a SW Evostar 90 for the last few months and I've learned a few things. I'm interested in taking this further and that my eyes are not suitable imaging equipment! (Mostly it's just a great way to see just how many floaters I have) I've taken some simple but nice images, but the Evostar really does love it's chromatic aberration. I have a Sony A5000 which has an APS-C sized sensor. Sadly my limited budget won't stretch to the 80ED and the SW x0.85 focal flattener. Would I be able to get reasonable results with my non-full frame camera, without a FF? If so, what else would I need to successfully attach my camera to the 80ED? (I already have a couple of T-mount adapters) Ideally I would have liked a shorter tube and focal length, but it seems the competition is slim (at least under £500) Thanks!
