This is a great package for doing deep sky imaging.  Bought in Oct 2016 from Woodland Hills Camera and Telescopes.  Paid $4600 for bundle.  Never used; all new in black case with 5 top of the line 1.25-inch Astrodon filters: LRGB and H-alpha.  Just priced filters on Optcorp website and they now list for $927 (tax and shipping extra).  Starlight Xpress Truis SX-694 combo package with filter wheel, OAG, and Lodestar 2X lists for $3350 on Woodland Hills website.  

Starlight Xpress Trius SX-694 Specifications

  • Power requirements: 115VAC / 240VAC @ 12VA, or 12VDC @ 900mA max.
  • Cooling system: Regulated set-point cooling supply with two stage thermoelectric cooler to give a CCD temperature of better than -30C below ambient.
  • Size: 75 x 70mm black anodized aluminum barrel with 42mm 'T2' thread at the CCD window end & input/output plugs at rear.

(Optional) Astrodon 1.25-Inch LRGB Tru-Balance Generation 2  Features:

  1. RGB filters designed to produce true color for galaxies and stars based upon a G2V (sun-like star) white point.
  2. Equal exposure time for each RGB filter leads to equal fluxes and equal color weights (combine ~ 1:1:1).
  3. Correct blue-green color for OIII in plane-tary nebula with 1:1:1 RGB color weights for correct star color.
  4. Two LRGB designs; E-Series for full-frame, and I-Series for Interline CCDs.
  5. Deep red filter in E-Series brings out HII regions in galaxies and better definition of H-alpha in emission nebula.
  6. All filters transmit an amazing 98% in their passbands for the highest perform-ance available.
  7. All filters are UV and NIR-blocked. No extra filters are needed.
  8. Breakthrough design eliminates halos around bright stars.
  9. Hardest optical coatings on 1/4-wave fused silica substrates for durability.
  10. Coatings extend to the edge (no uncoated rims that need to be blocked) and no edge-sealing is required.
  11. Light pollution suppression included in the design.

(Optional) Astrodon 1.25-Inch H-alpha 5 nm Narrowband Filter Features:

  • Peak transmission guaranteed >90-percent assuring you of the highest performance.
  • Bandwidths of 5 nm for general use and 3 nm for highest contrast, moonlight rejection and light pollution rejection
  • > OD 4 (0.01-percent T) out-of-band blocking
  • Hard-oxide coatings on clear 1/4-wave substrates go to the edge, eliminating uncoated rims that leak light.
  • Sides are blackened to minimize reflections
  • 3 nm filters can be used with fast optical systems to f/3 with little signal loss
  • Parfocal with all Astrodon filters
