  1. I have to say that while it is within the rules is it within what is morally acceptable? The fact that the item mentioned was sold. Someone was prepared to pay that price for it. We live in a world that some are prepared to argue that right is wrong and wrong is right. Just look at what people on SGL and UK Astro are asking for C8 OTA's. £700 when you could easily buy a used one for around £400 18 months ago.
  2. Still looking for an eyepiece of 12, 12.5 or 13 mm focal length with a 60° field. Thanks.
  3. Hello Ags. I like this topic you have posted. I to have a C6 and an concious of the need for collimation. May I ask what brand your 13.4 mm eyepiece is please.
  4. Just doing a spot of solar observing with my enhanced manual mount. I bought a fantastic 14 inch height extender from Andre,thanks. Great piece of machining from Germany. Blue colour finish looks good. Although with the black tripod, now black & blue like a painful bruise lol. Oh, by the way nice quantity of sun spots to observe with the Seymour filter, thanks Stu.
  5. Looking for a widefield 12 or 13 mm eyepiece. 60° or above. Thankyou
  6. I have recently added a C6 SCT to my Arsenal of instruments. I have enjoyed using it to observe the planets. I fully understand that it's primary function is for the moon and planets. I have though had pleasing views with my 80° Nirvana 16 mm eyepiece, an 1 1/4 inch configuration. This has got me thinking about the lowest power 1 1/4 inch eyepieces to use with the C6. There is the Televue 25 mm Plossl and the Televue and Explore Scientific 24 mm 68 ° . I wonder which of these would suit being used in my C6?
  7. Your Celestron CR150HD must be quite a grand telescope. I would love to look at the planets through it.
  8. Looking for a black 30 mm finderscope and mounting bracket for Synta/Vixen type shoe.
  9. Well I setup the C6. Could do more work on collimation. I may well buy an artificial star for that. But there were moments when I did see the Cassini Division ( Monday evening ). I am very happy with the C6 for planetary and Luna observing. It has a very manageable weight.while the C6 does not have the light gathering power of the C8. It does have a very noticeable increase in brightness compared to my previously owned C5.
  10. Sold thankyou. Celestron 102 mm Maksutov Cassegrain optical tube assembly. Complete with red dot finder and Astrozap dewshield. With Starbright XLT coatings.
  11. I've only had it a fortnight. It is collimated. So waiting for a long period of good seeing. I am hopeful though. Thanks.
  12. Overt the years I have seen The Cassini Division of Saturn on several occasions. With an 80 mm f15 achromat refractor and and American made Meade LX 90 eight inch. Over the last fifteen years I have found it really differcult to see. In fact I can't remember when I last observed it. This through a host of telescopes; an 80 mm Equinox ED refractor, a 120 mm ED refractor , a Celestron C8. I now have a Celestron C6 and my 80 mm Equinox and I am taking every opportunity to observe Saturn at this opposition. Is it a combination of poor seeing along with a telescope that is not capable of resolving The Cassini Division? Possibly my aging eyesight! Do you need a large apature and long focal length telescope?
  13. Below is a link to a YouTube film of a visual observers experiences. I really do like the observing accounts posted here. But also like video clips. My best view of M31 The Andromeda was with my eight inch Orion Newtonian. The sky conditions must have been super. I could see so much detail which was crystal clear. I do plan on looking through a Takahashi refractor one day. Watch "Daniel Mounsey shares his experience of astronomy." on YouTube https://youtu.be/gU7yOVt5y-Q
  14. For a speedy recovery.
  15. BMS 74800 microscope complete with glass slides and micro slide adjuster. LED illuminated. £45 plus postage.
  16. I would like to buy a Baader Click-Lock 2" for Celestron & Meade SCT. Model: baader-2956220Part Number: Thankyou.
  17. Ade, I think that you are well equipped when it comes to refractors lol. I once had an ED 100 mm. It did give sharp and high contrast views of the planets. At the time I mistakenly thought that you could improve on that.By getting a larger image of the planets (larger image scale) with a larger apature telescope. You probably can, but not with the sharpness of a quality refractor.
  18. You're absolutely right Stu. I have owned and sold some lovely telescopes. I still enjoy my 8 inch Orion. I now have some small to medium size telescopes and look forward to keeping and enjoying them. Thanks for your help.
  19. I now own a Celestron Nexstar 4 SE telescope. Other owners know that there is a flip mirror assembly at the rear of the tube. You can fit 1 1/4 inch accessories on the 90 ° angle. But there is a 35 mm wide thread at the rear. I would like to buy a visual back to screw onto this thread. I can then fit my 1 1/4 inch diagonal and 1 1/4 inch amici prism.Can anyone advise me where to obtain one please. Thanks Martin
