Manuf. No. SBIG STL-1001 E-C2

The same CCD was used in our previous ST-1001E camera. However, there were some limitations on the earlier model which have been eliminated with this design. The previous model did not have a self-guiding CCD or matching 2″ filter wheel due to physical constraints in the smaller ST camera body. Also, the predecessor model used the slower parallel interface. These things are now resolved with the larger Research Model camera body, 2″ internal filter carousel and high speed USB electronics.

Steiner 10×42 Peregrine

The optics of the Peregrine measure higher in spectral light transmission across the entire visible light range, on average, than all of our other closest performance competitors. This means you see colors more vibrantly and you can discover and identify species in more difficult settings and situations. The optical glass is manufactured at our new state-of-the-art roof prism glass production facility in Bayreuth, Germany. (See the graph below). Long eye-relief for eyeglasses, or extended, profiled eye-cups for hours of viewing comfort.

The Peregrines feature classic styling, in a beautiful non-reflective forest green color finished with a handsome falcon crest. They include a super comfort padded carry strap, rain guard, attached and removable objective caps and a deluxe case.

Narrowband (NB) filters enhance contrast of emission objects by accepting only a narrow range of wavelengths around the emission lines of hydrogen (H-a, 656 nm), oxygen (OIII, 501 nm), sulfur (SII, 672nm) and others.

They can be used to image when the moon is up, thereby extending imaging time. They can be used in light-polluted locations.

The narrow range of wavelengths is defined as the FWHM (full-width at half- maximum intensity). Narrower filters decrease the background noise. However, narrower filters are more difficult to manufacture consistently, and are thus more expensive. Furthermore, it is difficult to maintain high transmission through the bandpass of the filter as it becomes narrower. If the peak transmission decreases as the filter is made narrower, the emission signal decreases and the gain in S/N (signal-to-noise) is not realized. Astrodon has achieved this goal of high transmission for narrower filters.
