This Vixen Optics R200SS 200mm f/4 Reflector Telescopefrom Vixen Optics has a chromatic, aberration-free, Newtonian reflector that can resolve and split distant binary stars and separate individual stars in clusters. Its large aperture and moderate focal length results in a fast f/4 focal ratio ideal for observing and imaging the moon, planets, and deep-sky objects including galaxies, clusters, and nebulae. The R200SS is offered here without a tripod or mount head for those who already have a reliable rig and are looking to upgrade or add to their observation capabilities.

Q: 1. Does it need a second counterweight to do astrophotography with a dslr maybe an autotracker?

A: It depends on the weight of your camera body. If your camera body is over 2 lbs. I would suggest additional counter balance weights.

Q: 2. What is the size of the central obstruction(secondary+holder)?

A: It is 3 inches.

Q: 3. Does this come with a 2" diagonal?

A: The Vixen Optics VC200L 200mm f/9 Catadioptric Telescope (OTA Only) comes with the Vixen Optics Flip Mirror System which works as a diagonal but only accepts 1.25 inch eyepieces.

Q: 4. CAN I TAKE PICTURES BY CONNECTING MY CAMERA?

A: Yes you can, but you would need adapters to do so. I would need to know what camera model you have to make the proper adapter recommendations.

Q: 5. Can I use a 2" dielectric star diagonal mirror with the Vixen SD 81S or Vixen SD 103S? Thanks

A: The Vixen Optics SD103S 103mm f/8 ED APO Refractor Telescope (OTA Only) BH #VISD103S • MFR #ES26147 was only designed foe 1.25"

Q: 6. What is the difference between this A80MF and the A80M? Why is the A80M twice the price when they have nearly identical specs? Is it the quality of the glass? Or China vs. Japan manufacturing? Vixen website states A80M fully manufactured in Japan , with no mention of place of manufacture for A80MF.

A: Whenever Vixen's scopes has an f at the end, it means it is made in China. Otherwise, it is made in Japan. That is the only difference.

Q: 7. The description does not describe the telescope, only the mount. Is the Celestron 8" Newtonian is included?

A: It comes with the telescope, the Optical Tube Assembly (OTA) There is very little information available on Celestron website. 8” (200mm) f/5 optical design provides excellent wide field views Parabolic primary mirror minimizes spherical aberration to produce a better image.

Q: 8. Would the Celestron focal reducer work well with this scope, or does Vixen make one of their own that would?

A: Yes you can use the Celestron f/6.3 Reducer/Corrector for this Optical Tube. Website link: http://bhpho.to/1JT4a4N Also there is the Vixen Optics 0.62x Focal Reducer for the VMC200L & VMC260L Telescopes, which will be compatible too. Website link: http://bhpho.to/1JWik5n

Q: 9. Will Vixen Optics Porta II Tall+ Alt-Azimuth Mount work with this scope?

A: Yes it is compatible.

Q: 10. Does the VC200L ship with a 2 speed focuser?

A: The Vixen Optics VC200L 200mm f/9 Catadioptric Telescope (OTA Only), BH # VIVC200L, ships with a two-speed focuser.
