The StarSplitter Accessory is compatible with Digital SLR cameras. In order to interface to the StarSplitter's 1.25-inch output ports, you'll need a T-thread adapter for your digital SLR camera. Most will already have this as you need one in order to attach your DSLR to a telescope at all. In addition you'll need a 1.25 inch to T-thread adapter. This will go between the StarSplitter output port and the Digital SLR T-thread adapter. The next issue you'll encounter is that Digital SLR cameras require more backfocus distance than most other accessories. If you want the other StarSplitter port to be in focus at the same time, you'll need to extend that port's backfocus distance to match the DSLR's. This can be accomplished by adding an eyepiece extension tube. These are sold by most astronomy stores and extends how far back the eyepiece or accessory attaches by about 2 inches. Different lengths may be available. Once installed your StarSplitter should look like the pictures below and you should be able to achieve focus with a DSLR camera and an eyepiece or autoguider at the same time.

I have been excited about space since I was young, and have been involved in astronomy for over 20 years. I have built 4 of my own telescopes and continue to design and experiment with new instruments and accessories. Archives
