So, how does a H Alpha lens do at night when you remove the solar filters? You be the judge. Moon |

Something is wrong with the host forum. I can't get them to come up anymore either.
I put new direct links to the images. Keep in mind this scope produced these great images because the moon is basically monochrome (black and white). The lens was designed for H Alpha so it would not perform well in color i.e. planets. It does however show off the quality of the lens. These images were much higher resolution with fantastic detail. I had to reduce the resolution so they wouldn't take so long to load.

They are the most incredible lunar pictures. I know this telescope performs well on the sun but this made my jaw drop. I know that imaging with a red filter produces the mostdetail on moon and planets. Is the same effect with best correction in the red part of the spectrum resulting in the incredibly high resolution? Had I not known I would have thought these images were produced using an apochromat or large long focus newtonian.

Have these been posted in several forums over on CN?? If not maybe our "friends" Ya and Hoo might like sharing them with others.  Mike |

Thanks to all  Yes for the lunar or planetary imaging we use systematically a red or infrared filter to limit the effects of the turbulence My next objective, when I would have time!!! , it is to test the ota 228mm in deep sky with my Atik 4000 CCD, i think that we can make interesting things also in this domain, in particular in HSO, to follow.... |

Which Istar lens or scope was used for the moon images?

Jon, it's a custom built 228mm solar scope designed and built by JP Brahic out of France. The lens was designed and produced for maximum H alpha transmission but it seems to perform well on other objects as well.
