  1. I started with a 150P on a manual EQ3-2 and really enjoyed the experience but decided for visual the faffing around with a Newtonian on an equatorial mount was getting frustrating. A little over a year ago the boss gave the OK for me to spend on the GOTO Dob. in my signature. I kept putting it off as it seemed a lot of money to spend on the hobby and eventually brought it January this year. The poor weather has restricted my use but from the experience so far I 'm glad I made the decision and sorry I didn't commit earlier. From what I have found the alignment is a five minute job and if carried out carefully produces very good GOTO results. FWIW the first night I used the GOTO I viewed about 20 objects which is considerably more than I ever did manually in a single evening. With this scope it is possible to push the OTA to the approximate position and then home in using GOTO. To do this my sky knowledge picked up with the 150P has been very helpful.
  2. The 200P is a great choice, many will say it's the UK's most popular scope. As far as eyepieces go, use the scope for a time and you will have a better idea of what you need, when the time comes there will be plenty of advice here. A garage is an ideal place to store your scope, I've always stored mine there, as it is likely to be close to outside temperature and so will take little time to cool when taken outside. Just make sure creepies are kept at bay. Good luck.
  3. Thanks for posting a great image of this fascinating crater.
  4. Good to hear you've earned yourself a few Brownie points.
  5. +1 ^^^ Also you need to keep both eyes open and move the scope until the two images coincide.
  6. It's all a learning curve. Great image BTW
  7. I'm purely visual and after six or so years am still amazed I can go out of my own back door with fairly modest equipment and spend time observing objects most of the human race has never seen.
  8. My original calculation was only by way of example. The 32mm is actually the EP I use but substituted 30mm to make the calculation easier.
  9. You know how to calculate magnification? Divide focal length of scope by focal length of EP. For you and I that's 1200/EP focal length. To arrive at FOV divide apparent field of view of EP by magnification. To take an example:- use a 30mm Plossel, 1200/30 = 40. A Plossel has about 50 degree apparent field. From this the true FOV is 50/40 =1.25. HTH.
  10. Good luck with the new mount, it was only yesterday I was wondering if you had received the replacement. As you know I also had the noise problem and the replacement has been fine. Regarding alignment I found by following the instructions in the manual put objects in the inner third of of a 1.25 degree FOV EP. To be sure you have Polaris in the FOV try upping the magnification, you will find Polaris is a double. Good luck and let us all know how get on.
  11. You only need the parrot for the complete kit
  12. Hi charl, I received my copy this am and was very surprised to find the enclosed moon map which was a nice surprise. The Moon Watch article this month is a very interesting one about Aristarchus. Enjoy.
  13. Thank you Avani for another fine image and write up from the master.
  14. Take time to observe an object, don't get it in the FOV and then move on. To aid this the two best accessories, for me, are an eyepatch and a comfy seat. And lastly enjoy the experience.
