Latest Images with the TeleVue "is" series and the STL11000M
Updated January 6, 2008
 
The SBIG STL11000M is a large-format CCD camera with a 24.7mm x 36mm chip, the same size as a 35mm film frame.
The new Tele Vue NP127is is a 127mm f/5.2 Nagler-Petzval apochromatic refractor,
while the Tele Vue NP101is is a 101mm f/5.4 Nagler-Petzval apochromatic refractor,
and the new Tele Vue TV-102iis is a 100mm f/8.6 apochromatic doublet.
These three telescopes are specifically optimized for imaging with large format CCD cameras.
The field of view with The STL11000M and the NP127is is over 3 degrees wide and 2 degrees high.
The Tele Vue TV-60is is a 60mm f/6 apochromatic doublet,
which delivers pinpoint stars, corner-to-corner for CCD cameras with chips up to APS-size.

NGC7822, including Sharpless 2-171, a.k.a Cederblad 214 in Cepheus. This luminance channel for this image is the stack of 12 eight-minute exposures taken through an Hα filter, shown below. While shooting the color data I was plagued with clouds, and was only able to save 5 reds, 6 greens and 4 blues at 8 minutes each. I threw away the red data and used the Hα for the red. I added the green images and the blue images together, and used the result for both the green and the blue channels. I then sigmoid stretched the Ha and used it as the luminance. This worked because the red data from the nebula is all from the Ha emission. The blue-green is all from the OIII. So treating the filtered data this way gives you a pretty reasonable color rendition. Only the star colors suffer, because stars are broadband emitters, unlike nebulae, which are emission line objects. A little bit of the AIP4Win Star Color Tool fixed that up quite nicely. All images were acquired using an STL11000M CCD camera on a Tele Vue NP101is. The exposures were calibrated, defect-corrected, stacked and color-combined using AIP4WIN V2.

STL11000M & NP127is
This picture shows the Tele Vue NP127is and the SBIG STL11000M as they are currently set up in my observatory. They are mounted side-by-side with a Vixen R200SS 8" f/4 Newtonian. A Tele Vue TV-60is 60mm f/6 refractor is mounted above, where it does double duty as a guidescope with an SBIG STV, or as the ultimate wide-field imaging rig. This load is comfortably carried by a Losmandy Titan mount.
The electric focus and digital readout on the NP127is is an amazingly useful feature. With the digital readout's remote interface cable, I can sit at the computer and focus the telescope, and return to a specific focus position at any time, and see the focus position displayed on the monitor.

Pier
For a real hoot, you can look at all the cables connected to the instruments above. The pier is a 4" concrete and rebar-filled steel pipe, anchored in 4 tons of concrete. It doesn't move. All the cables are routed in 2" conduit under the observatory floor.
