Ah, this would be the one: http://www.caa-cya.org/newversion/fg....php?counter=0 (second pic down) Yes, looks like it... so that's a C14, right? The C stands for Cassegrain. It's a reflector with a clear corrector plate at the front covering the opening. There are Schmidt-Cassegrains and Maksutov-Cassegrains and they have different types of corrector plates. Get yourself a copy of the November issue of the BBC Sky at Night Magazine, it has all about telescopes this month. Pete Lawrence also does a monthly article on astrophotography. -- Regards - Rodney Pont The from address exists but is mostly dumped, please send any emails to the address below e-mail rpont (at) gmail (dot) com |

Great, thanks for the magazine suggestion and explanation. -- PMatos |

On or about 2010-10-27,
Paulo J. Matos illuminated us with: Sorry for tracking you down online but what kind of telescope do you have here? http://homepage.ntlworld.com/mark.ay...s/BENQ1022.JPG That's just a cheap hand-held thing that happens to project the sun well without melting anything inside itself. It was a great way to follow the Venus transit, but fairly useless for anything else astronomical. I wouldn't try doing that with anything expensive due to the possibility of damaging something by heating it inside. I used that setup to show the event to some of the children at our local school. -- Mark Real email address | You will never find anybody who can give you a clear and is mark at | compelling reason why we observe daylight savings ayliffe dot org | time. |

A C14 (http://www.celestron.com/c3/product.php?ProdID=114) is a particular model of telescope made by Celestron. This picture appears to be of a roughly equivalent Meade. -- Cheers, John |

This picture appears to be of a roughly equivalent Meade. To me, that photograph doesn't look like anything past an 11-incher. Meade makes a 16-inch SCT, but I didn't think it ever made a 14-inch SCT. Maybe the club does own a C14, and they accidentally put a picture of a smaller Meade on the web site instead. Ah, but a web search http://www.flickr.com/photos/grantbrummett/4524575304/ tells me I'm mistaken, and Meade does make 14 inch SCTs. John Savard |

Hi all, not posted on usenet for a long time! Here's a shot of Jupiter I took with my C-14 on the night of September 3/4 2010. This particular shot was taken just as the planet's giant moon Ganymede was exiting from Jupiter's disk. http://www.digitalsky.org.uk/jupiter...9-45_RGB15.jpg really nice. Please keep posting! |
