Unbelievable
http://www.spaceweather.com/swpod200...l05/favre1.jpg
This was taken with a 'lowly" SW 80/400 achromat. It rivals some of the best AP and TV shots I have seen. The OTA sells for a measly 150 US!! http://www.islandeyepiece.com/telescopes/sw804.htm |

The OTA sells for a measly 150 US!! http://www.islandeyepiece.com/telescopes/sw804.htm If you're using a hydrogen alpha filter, you don't need good color correction because you're looking at a very narrow band of light. |

It would seem that the achromat doublet is of good quality for a cheap price!! |

China" you mean "Red China," AKA "The People's Republic of China." Skywatcher scopes are made by Synta. The Taiwanese firm. As we discussed some time back. ;-) The Orion Short Tube 80 is also made by Synta. Peace, Rod Mollise Author of _Choosing and Using a Schmidt Cassegrain Telescope_ Like SCTs and MCTs?

Thank god that money is still not the only path to sucess in astronomy. I guess it's possible to buy your way in, but, even then, as I said in another thread, the skill of the man or woman behind the eyepiece is still more important than the pedigree of a telescope.
