This item is in stock and ships the same day you order.

The total distance from the camera sensor to the grating when using our AD-T2 is about 60 mm. Use this number in our calculator: www.rspec-astro.com/calculator. If you put your Star Analyser grating on the camera side of the grating, the distance is 53 mm.
