Here you can see imaging setup with Voigtlander Macro APO Lanthar 125mm f/2.5 SL telephoto lens. It comes with the lens shade around which I usually wrap a dew heater. The lens is very handy for taking wide field images. It is attached to the ST2000XM / CFW10 via an adapter custom made by Precise Parts. The optical design of the lens is made of 11 elements in 9 groups, including 2 ED elements. The lens body is made 100% of metal and has a very solid feeling. |
This picture shows imaging setup with Rubinar 4.5/300. I use this setup for imaging of more extended objects. Rubinar is a catadioptric Maksutov lens (of Rumak variety), made by well known Russian company LZOS. Good thing with this lens is that it can reach infinity focus in combination with ST2000XM + CFW8a + M42/T2 adapter. Rubinar has a rather precise focusing mechanism, so focusing with it is easy. With the lens you also get a very useful dew/glare shield. Around the shield you can see a dew heater with a temperature sensor attached. |
Here you can see my imaging setup with Nikon Micro-Nikkor AF 200mm f/4 D ED telephoto lens. It is attached to the QSI583ws camera using QSI Nikon adapter. I use this lens for imaging of the more extended deep-sky objects. Optical design of the lens is 13 elements in 8 groups, including 2 ED elements. Its optical performance is stunning. There are no aberrations whatsoever, even wide open (f/4), on APS size sensor. The lens is built like a tank. It comes with sturdy non-removable tripod collar which is perfect for fixing of the lens to the mount. Lens hood (wrapped in dew heater) is optional, but necessary for astroimaging. |
