Ideal for deep-sky imaging with a DSLR or dedicated astronomy camera, the iOptron 150mm f/4 Imaging Newtonian Telescope OTAfeatures a fast focal ratio for photographing fascinating objects. The OTA's primary mirror is made of BK7 optical glass with a quartz protective layer. The tube has an 8x50mm finderscope and a 2' Crayford-style focuser with a 1.5" adapter, which is compatible with iOptron's Electronic Automatic Focuser. Mounting rings secure the tube to the 8" Vixen-style dovetail plate for connecting the tube to a mount.

Q: 2. Could you use with Skywatcher EQ35 mount?

A: Yes,both are compatible & use the same Vixen-Style Dovetail Plate.

Q: 3. What's the weight of the 8 OTA version?

A: Yes this OTA has a Vixen Style Mount, so it will mount onto that Tripod set up.

Q: 5. What is the maximum effective magnification? on the iOptron website I see 180 but I would expect around 300, from a 6" telescope. Can you please clarify?

A: The magnification is approximately 27X without an eyepiece. That now changes when you add the magnification of the eyepiece into the equation.

Q: 6. If it weighs 18 lbs. why does it say its Package Weight is 15 lbs?

A: A correction order has been submitted to the B&H web content team.

Q: 7. Does it come with a tripod (stand) or where can one be gotten?

A: So it does not come with a Tripod unfortunately. However you can buy one for the model. The BRESSER Exos-2GT Computerized German Equatorial Mount with Tripod would be a great choice.Website link: http://bhpho.to/2bN3Fx3

Q: 8. Is the focuser and the primary mirror threaded together? meaning are they coupled in such a way, when the focuser moves primary mirror moves with it? Thanks

A: No, when using the iOptron Photron 250mm f/8 Ritchey-Chrétien Catadioptric Telescope the focuser and the primary mirror are not threaded together. iOptron describes it this way: "With the primary mirror fixed in place, iOptron installed a precise two-speed Crayford-style focuser with a 10:1 reducer that allows for fast coarse and precise fine focusing without the backlash that occurs in the more common rack-and-pinion design—essential for astrophotography or splitting objects that are close together, like binary stars."

Q: 9. What type of finder scope and diagonal are required to use this scope? As in, what are the specifications to purchase the right items to fit on the scope?

A: On the diagonal. You have to decide on 45 degrees or 90 degrees. also a regular diagonal or an erecting prism diagonal. When you look through a telescope the view is always inverted with out the use of some kind of erecting device. B&H most popular finder scope is the Celestron StarPointer Finderscope BH #CEFSSP • MFR #51630 https://www.bhphotovideo.com/c/product/202036-REG/Celestron_51630_Star_Pointer_Finderscope.html https://www.bhphotovideo.com/c/product/202036-REG/Celestron_51630_Star_Pointer_Finderscope.html

Q: 10. What is the maximum effective magnification? I am asking since at the iOptron website its wriiten 180, however other 6" telescopes usually have around 300 max effective magnification. Thanks

A: The stated lower magnification could be because of the stated shorter focal length of the OTA.
