  1. I am terribly sorry but your words have failed to convince me. The star test shows me that the method I am using is working. The simple approach works for me and nothing you have said above gives me a a reason to change. I certainly have no wish to introduce another tool/variable into the equation. I think it is best to let others to do their own research and make their own judgement on what is the right method for them including the validity and suitability of the links I posted.
  2. I think you have made an excellent choice then I would wouldn't I A copy of Turn Left at Orion and a willingness to take your time and you will have a solid foundation in my opinion.
  3. My advice would be to spend the waiting time planning your targets with a copy of Turn Left at Orion and reading the posts on here. I would definitely not spend any money until you have spent time with your telescope and found what is can and cannot do. For example, you may decide that an alternative finder is a priority over a zoom eyepiece or maybe you decide that only need to replace the 10mm one? Then there are the accessories like a chair and red light you may need to consider.
  4. Not everyone agrees with the "rankings" but this is quite fun...
  5. That is not my experience. If collimation using a cap results in a star test showing my telescope is collimated that is fool proof to me and demonstrates that there is no benefit in introducing another tool. I am happy to follow the following advice... Gary Seronik’s no-tools collimation advice https://garyseronik.com/a-beginners-guide-to-collimation The Small Optics guide at https://www.youtube.com/channel/UCVi6UI5BvXm9lyZg5AG0X1g/videos Collimation myths at http://web.telia.com/~u41105032/myths/myths.htm Zen and the art of collimation http://uncle-rods.blogspot.com/2009/07/ze
  6. Interesting in that the sites I use recommend just the opposite. Still if it works for you!. I will stick to the "KISS" approach of just a collimation cap.
  7. As well as the Bortle map, I have started using the light pollution map which gives me an indication of local areas that are less polluted. https://www.lightpollutionmap.info
  8. Some have questioned Gary's method of approximately aligning the primary before the secondary but I think that he does that to ensure the primary is not way off. He does go back to the primary.
  9. I don't have a problem with the default Teflon pads. I tweaked the tightness of the central bolt so the discs would move freely but not be too loose. I've heard some have used a couple of CD's as anti-friction mounts which I suppose could work. I thought about carnauba car wax but then what is the point when there isn't an issue?
  10. I have come to the conclusion that none of the printed star atlases cut the mustard when it comes to observing at the eyepiece. They don't have enough detail. Olle Errikson's "The Night Sky Maps" 30 charts and Michael Vlasov's A3 are the closest to what I might be able to use. I currently use Stellarium (desktop version not the app or web version) when planning targets or for printing off ocular views on A4 (inverted colour). At the eyepiece, most of the time I use SkEye on my Android phone but will occasionally fire up Stellarium. I do have an iPad but I've not used it at
  11. If you consider going down the Zoom route as I did, then this may be of interest.
  12. I would recommend this. Although it is popular with Dobsonian owners it does equally apply to Binocular users and is written for them as well.

    Yes the 200P is a great Dobsonian. That used price is more than I paid for a new one last year though I would get use to it before considering any upgrades but it was a very short time before I replaced the EPs and got a Telrad. I've put my first impressions of the Skywatcher here and I would definitely recommend the finder safety harness.
  14. As well as Gary Seronak's guide mentioned above, I like Uncle Rod's guide http://uncle-rods.blogspot.com/2009/07/zen-and-art-of-telescope-collimation.html?m=1 And this video takes the same "KISS" approach...
  15. I would not spend a lot of money on your existing telescope. I believe it comes with a 10mm EP which I don't think is going to be usable. The 25mm will be better but I would look out for a used plossl between 28-32mm.
  16. I would stick with SkEye and Indirect mode. Yes it has quirks but with the magnetometer calibrated, I find it works really well with my Telrad and lower power, wide angle EP. Ref https://astro.catshill.com/skeye-a-push-to-finder-app I also found 52 Ori difficult to split and I only gave it a 2* (W+W). My favourite doubles in Orion (so far) are: 5*: Rigel, Theta1/Trapezius of course, Sigma 4*: Iota, STF 761, STF 848, Delta
  17. This page will give you a better idea of what you can see through an eyepiece. http://www.deepskywatch.com/Articles/what-can-i-see-through-telescope.html Perhaps it is not what you were expecting, but for me, seeing live the brightness of the trapezium in Orion, the jewels of the double cluster near Cassiopeia or the gold and green/blue of the binary Almach in Andromeda knock spots of any digital photo I have seen. I would stick with it.
  18. It does seem strange that the 200P classic does not come with one
  19. I paid £23 but it is worth it IMHO. Someone did find a used one on FB marketplace for a tenner, so you might get lucky
  20. I know what you mean. I replaced the straight-through finder with a RACI to reduce bending down and this has worked. However my ideal would have been a none-correcting RACI. What has helped is a low power (42mm), wide angle (65°) eyepiece which does the job of the straight through finder.
  21. Turn Telrad off. Move telescope and Denver chair into side building. Fit covers to Zoom, wide-angle EPs and barlow. Put into case. Fit covers to finder and focuser but not OTA. Tilt OTA down and loosely cover with sheet. Take sketch pad, pencil and printed maps inside house. In the morning, turn OTA to vertical and fit end cover. Come up with excuse(s) as to why I brought up mud and leaves inside.
  22. A Dobsonian and a copy of Turn Left at Orion is a great choice. I wouldn't get hung up or start panicking about collimation. You can order a collimation cap when you get your telescope. I made one from a lens cap and a shiny washer. When you are ready, check out these... https://garyseronik.com/a-beginners-guide-to-collimation https://www.youtube.com/channel/UCVi6UI5BvXm9lyZg5AG0X1g/videos
  23. Excellent thank you. At least two will go on the list! I split Wasat last night, definitely a 5* and a lovely white with orange companion. 10-8mm zoom.
  24. Thanks - STF 848 (and 844) will go on the list Pike
  25. Excellent thank you, I see that that the corner of the "L" is also a Y+Y double but a wide one (STF 844)
