Related Questions and Answers

Q: 1. only black color?and only Dec BracketPolar Scope Illuminator ?

A: The illuminator is a poor design. You need to remove the bracket to use it on the polar scope. With a mount this light (and the non-heavy duty tripod I supposed most people will be using), re-attaching the bracket and camera will require you to do PA again.

Q: 2. If this requires alignment with Polaris, how would you go about aligning it during the day for solar tracking?

A: I use the compass on my iPhone 6. I set the compass to true north . I lay the phone up against the wedge and align. There are several reasons why this shouldn't work, but it does. I have run the equatorial mount for several hours and have only had to make small adjustments. Getting the equatorial mount level is equally important.

Q: 3. can you point me to a telescope to use with this package? thank you

A: Hello. I would recommend a small diameter refractor, such as an Orion. You must consider the weight of the telescope because the capacity of the guider is limited. For heavier scopes, such as the smaller SCTs, I would purchase the 1 kg counterweight. I'm currently using a Canon DSLR with a 200 mm telephoto lens + 1.4x extender and use the counterweight to minimize torsion stress on the guider.

Q: 4. If I have a standard camera tripod and DSLR, can I go straight into photographing the Moon, Orion Nebula, etc., without purchasing *anything* else, or must I also get the counterweight, any kind of wedge, ball head, etc. for it to be a complete setup? I am comparing this to iOptron and need to know what else is required.

A: Using a DSLR should not require you to use a counterweight unless the camera and lens combo approaches the 11 pound threshold. I purchased all of the accessories just in case they were needed I'd have them to use. I only use the counterweight when affixing my ETX to the ball head. Depending on the total weight of the camera and lens, coupled with the stability of the tripod you have, you may want to have some form of counterweight, even if just for the tripod itself, to ensure steady images.

Q: 9. Can this unit be used with film cameras?

A: Yes, really no different than a digital camera but if you have them I'd recommend staying within parameters established for a like focal length and ASA/ISO value just for ballpark exposure.

Q: 10. Does this package include the EQ wedge and counter weight?
