Product QuestionsWill the Shelyak 600 spectrograph work with the Orion StarShoot Deep Space Video camera II and a 10" Newtonian?Question by: maxwell1 on Jul 22, 2014 3:12:36 AMAccording to Shelyak, the Alpy 600 will work with any CCD camera using a T-thread attachment and a back focus between 10.5 and 21mm. The Orion Deep Space Video Camera uses a C/CS mount thread and so would need a very short T to C adapter like the Teleskop Service version and should work with or without the included 5mm spacer ring (~16.5mm back focus without, ~20.5mm with).
Including the camera, the back focus of the Alpy 600 is 75.5mm-86mm, so you will need at least this much available back focus above the height of the focuser to reach infinity focus with the unit. The body of the spectrograph is 45mm in diameter - too small for a 2" attachment - so you will need to use the 1.25" nosepiece. If you don't have enough back focus for this, you may need a lower profile focuser or you may need to shift the primary mirror closer to the secondary.Answer by: Chris (Admin) on Jul 23, 2014 12:25:32 PM
