  1. I tend to use a 7mm Celestron X-cel LX for planets in my 8" dob.
  2. You won't be able to fit both the 1.25" adapter and a 2" eyepiece at the same time and it is unlikely to be threaded for 1.25" filters anyway. It might be threaded for 2" filters which would allow you to use 2" filters with both 1.25" and 2" eyepieces. You wouldn't want to use a 1.25" filter with a 2" ep because the use of a 2" barrel is dictated by the field of view and to block the outer 0.75" will vignette the image. However, a 32mm Plossl is usually found with a 1.25" barrel and so supplying one in a 2" barrel is probably more of a marketing ploy than anything else. The Z8 will be a lot more useful than the 60az under all skies. Yes, there will be diminishing returns with larger apertures but to be honest the 60az is really a bit too small and so the difference between the two will be significant. I have no experience with US retailers and so I will leave that to others to advise.
  3. Are these magnifications that you find using in all scopes or just in your cpc100? I would suggest that for several of those exit pupil is probably more important and that the magnification will therefore change depending on the scope being used.
  4. For £60 or less a piece the BSTs are probably as good as you're going to get. There is also the Celestron X-cel LX range but the performance is pretty much the same so it just depends which focal lengths you want. Even though the correction of an ortho is going to be better I would choose the extra field of a 60° eyepiece and comfort of a twist up eye cup for a general purpose eyepiece. Also if you are considering the 6mm WO SPL Tring Astro sell the Altair Astro Lightwave, which is probably the same eyepiece in a different skin, for significantly less (£55 I think).
  5. If you already own a dslr and heavy duty tripod the Skywatcher Star Adventurer might be an option to allow you to just take long exposure photos with the camera. You'll have to do some research into what is achievable with that set up and see if it matches with what you are wanting to do.
  6. An 8" Dob is a good choice for purely visual use but if you want to get into astrophotography you'll need to increase your budget just for the mount. The two different disciplines really require two different setups. The book Making Every Photon Count is usually recommended for anyone thinking about astrophotography.
  7. At £50 each I think BST Starguiders will be your best bet. The 12mm is nice and will give you a 2.4mm exit pupil which is ideal for DSOs so I'd start with that.
  8. Those should do to get you going but I imagine they are not of the best quality. What sort of budget are you thinking per eyepiece?
  9. BSTs can be had in the UK from Alan at Skies the Limit (Skies unlimited on eBay). Both the BSTs and X-Cel LXs stop at 25mm because at a 60° apparent field of view you're almost at the limit that a 1.25" barrel can show. If you want a noticably wider true field you'll need something in a 2" barrel which is going to be even more expensive. The Explore Scientific Maxvisions are probably your best bet but then you're talking £100+. You'll also need to make sure you've got the 2" eyepiece adaptor for your focuser, I think that it is a separate part on your scope. If you don't have it then astroboot tend to have them fairly regularly.
  10. How limited is limited? I think the BST Starguider and Celestron X-cel LX ranges are supposed to be ok at f5 if £50-60 per eyepiece is not too much.
  11. Does the scope come with any eyepieces? If it does I suggest starting with those and getting a feel for what you are missing.
  12. Make sure you have allowed your scope to cool properly before trying high power viewing. If you have stored it indoors then I think the general guidelines are along the lines of 10 minutes per inch of aperture so at least 80 minutes. As others have said, the seeing was pretty bad here recently so you may have also experienced that. I regularly use a 7mm eyepiece with my 8 inch dob so a 6.5mm should be fine.
  13. The Celestron Regal I linked to earlier still has no bids on it at this time making it both cheaper and significantly better than those three scopes. I think you should look for a spotting scope with ED glass so you get APO or Semi-APO views because it makes a massive difference. I looked at the Acuter review video and it wasn't the chroma that stood out, but the general blurriness of the entire image.
  14. If you are still unsure about which screws are which I have marked the primary adjustment screws (phillips) in red and blue and the primary locking screws (Allen key type). It looks like the screw I have marked in blue might be slightly damaged so I would try to collimate using only the other two screws if possible.
