SPECTRAL Adapter spacer for filter type SA100 S/C for Schmidt - Cassegrain telescope
This adapter allows you to make two important adjustments when using a Star Analyser diffraction grating:
1. Rotate the Star Analyser in place: the ideal orientation of the spectrum on your sensor chip is exactly horizontal. The yields the best spectra because it eliminates the need to later rotate your spectrum using software (which can introduce artifacts).
2. Change the adapter distance from the sensor: by adjusting the distance between the Star Analyser and your sensor, you can change the length of the spectrum that is projected on the sensor. This allows you to maximize the spectrum to take full advantage of your chip size without overflowing off the chip. The result is higher resolution spectra.
Our spectral adapter can be increase the sensor distance up to 34 mm. You can easily add T2 extensions. See article 3037.
The spectrum to the left taken using the using the SA filter ( 100 l/mm, see below) using The Imaging Source DMK41 AS CCD B&W camera. It was processed using the RSpec software, available from https://www.rspec-astro.com/ .
The software, CCD and the Star Analyser filter are not included and must be purchased separately.
The adapter can be used with these leading spectroscopy programs:
1. VSPEC (free software in English) This is the one of the most powerful and best spectroscopy programs. However, it is also more difficult to learn. https://www.astrosurf.com/vdesnoux/
2. RSpec (commercial software with 30-day free trial, in Italian) allows you to take and process the spectrum in real time, compatible with virtually all formats of video and photohttps://www.rspec-astro.com/
