    Celestron C5 telescope eyepieces.

    Hi Moonshine. I like to use the C5 to take to darker skies near where I live. The C5 being f10 does not lend itself to wider field viewing. I somehow got it into my mind that any eyepiece above around 16mm would distort the image horribly. But encouraging to know that reasonable views can be got with 24 mm 1 1/4 inch eyepieces.
  2. I have a Celestron C5. I am considering ways to improve it. I have several wide field 1 1/4 inch eyepieces, the longest focal length being a 16 mm 82 degree. I was wondering how a wide field 20 or 24mm Eyepiece would work with it. There ie also a 32 mm Plossl.

    Voyager 2 Doesn't Leave Solar System

    Could a similar type of probe arrive here one day? Sent out by a civilisation long gone many thousands of years ago.

    Celestron C5 OTA & focal reducer.

    Thankyou for your replies.
  5. I have used an f6. 3 focal reducer with Celestron's C8 and C9. They worked very well. The apature behind the visual backs were wide enough to fully utilise the reducer. But, can a focal reducer work with a C5 SCT. The apature behind the visual back on a C5 is narrower than the C 8 & C 9.

    Landing Party!

    I remember the excitement leading up to the two Viking landers in 1976. The first successful landers. These gave us our long awaited first views of another planets surface.

    I have always typed in "nasa tv" into a search engine. All rocket launches are streamed live there

    The Hyades in Taurus

    Nice image. I like to look at this with a low power Eyepiece.
  10. Hi Chris. Brave to put the small Newtonian up against an institution. The good video works well. Thankyou for producing it. Martin
  11. It was great to meet up with you all. With regards to the moon, I think that it's a case of getting out when we can. I enjoyed turning the refractor to the moon. Until the next time.
  12. That is a pleasing image Peter. Especially as the conditions were differcult. The double cluster is there. One of my fav targets. Thanks.
  13. I agree, thanks Kevin. And thanks to Peter, Kevin and Ade for a lovely observing meet up. Look forward to another. Just what I imagined a great observing meet up would be like.

    Your four-legged star-gazing companion

    Here is my astro dog friend Louie. He is guarding our telescope here. Love him to bits.
  15. Hello, it's grumpy martian/Martin. I am down in Swanage this weekend. Saturday is the evening that I can meet. I will bring my ED 120 refractor.
