The observational equipment available is:
NEQ6 Pro SynScan Go-To
Astro-Tech 8″ F/8 Ritchey-Chretien Astrograph (carbon fiber tube) with JMI motorized focuser
Meade 80mm F/6 triplet apochromatic refractor with MoonLite motorized focuser
Atik 314L+ CCD Camera with Atik EFW2 9 position 1.25″ motorized filter wheel
Philips Toucam Pro webcam modified with ICX098BL sensor, peltier cooled and radiator, used mainly for guiding and star field matching (orientation) purposes
Imaging Source DMK 21AU04.AS camera with ICX098BL sensor, the same sensor as used in the above custom self-built camera
This camera is used as a guider for the Alpy 600 spectroscope and also for planetary photography.
Canon EOS 400D DSLR modified for astrophotography with Baader BCF Filter
Astro-Tech 2 inch field flattener
While the Ritchey-Chretien telescope’s two-hyperbolic-mirror design manages to eliminate the nasty off-axis asymmetrical aberration known as coma, it still has off-axis astigmatism and field curvature.
Though I prefer pure Ritchey-Chretien reflective optics for more precise scientific observations (virtually all professional Observatories use RC Telescopes, Hubble Space Telescope is also RC by design) , the field flattener lenses can be useful sometimes, especially for wider field “pretty pictures”
Also, the field flattener is mandatory for wide field photography through the Meade refractor.
Baader CLRGB 1.25″ filter set
Alpy 600 spectrograph with guiding module
I can use the above equipment in various configurations:
Atik 314L+ CCD Camera and motorized filter wheel mounted on RC telescope
Modified Philips Toucam Pro webcam mounted on the Meade refractor for guidance
Atik 314L+ CCD Camera and Alpy spectrograph with guiding module and off-axis guiding camera (DMK) mounted on RC Telescope
Philips Toucam Pro webcam mounted on the Meade refractor for star field matching and precise target acquisition (orientation)
Canon EOS 400D DSLR mounted on Meade refractor
Atik 314L+ CCD Camera and motorized filter wheel mounted on RC Telescope
DMK with 3x barlow and filter wheel mounted on RC telescope for planetary imaging
Atik 314L+ CCD Camera mounted on Meade refractor
