Celestron C11 XLT My main instrument for planetary imaging is a Celestron 11 XLT (279mm/2800mm) on a Losmandy G-11 mount. The C11 is the successor of the C8, which was sold in 2011. This system is really huge! When I assembled all the components for the first time, it got bigger and bigger. But I think it is still portable. |

Takahashi FS-102N
Apochromat I was able to catch one of the last Takahashi FS-102N refractors (since this telescope has been discontinued by Takahashi). The FS is an air spaced doublet fluorite Apochromat (Fraunhofer design). The front lens is made of CaF2, a synthetic grown calcium fluorite mono crystal with excellent optical performance. Aperture is 102mm, focal length is 820mm (f/8). The picture on the left also shows a 2" diagonal mirror and a 6mm Vixen LV eyepiece. |

TMB-LOMO 80/600
Apochromat My latest purchase is a TMB-LOMO 80/600 refractor (March 2009). This refractor is very portable and will be used for "grab and go" observations. The objective is a triplet made by LOMO optics (Russia). With each lens, LOMO includes a test report with RMS and PtV values. For this telescope the RMS (at 546 nm) = 0,022 which results in a Strehl value of 0,981 (nearly perfect optics!). The tube is from Germany with fully retractable dew shield cover. The focuser is a US-made Starlight Feather Touch with 1:10 reduction, so this telescope is truly international! |
