The Tiffen 127mm Black Diffusion/FX 4 Filter diffuses strong light entering the lens and produces a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. This filter has a 4 density, providing a noticeable amount of softening.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Diffuser filter provides an ethereal quality to photographs, resulting in a dream-like atmosphere.

Soft image quality does not detract from the overall detail of the image.

Q: 2. Does this telescope have large asteroids (Ceres, Vesta etc.) in it's database?

A: No, asteroids are not featured in the NexStar hand controllers database; however, you can manually enter in an asteroid's RA and DEC coordinates to command the telescope to slew to an asteroid. You can also add the SkyPortal WiFi Module and using the free planetarium app, SkyPortal, command the telescope slew to asteroids in its database. Sincerely, Garrett at Celestron

Q: 3. Can this telescope be used with GPS Navigation such as Celestrol SkyQ Link II ?

A: Yes it can. The Celestron SkyQ Link II will be compatible with this scope.

Q: 4. Who uses it for photography thats what I am looking for I will be mounting a Nikon D700 and am looking for clean crisp photos?

A: This scope would be good for taking a clear photos. The mount takes into effect, but that's if you are really trying to get more advanced. I would start with this first for shooting photos. You would need 2 adapters to attach your Nikon D700 Camera onto. The first would be the Celestron-SLR (35mm OR Digital) Camera Adapter.

Vello Lens Mount Adapter-T-Mount Lens to Nikon F Mount Camera would be perfect. Website link: a href= http://bhpho.to/1d8lKOS target= _blank http://bhpho.to/1d8lKOS/a

Q: 5. What type of focuser does this unit have? Is it a bird Jones?

A: The scope is outfitted with a 1.25" rack-and-pinion focuser.

Q: 6. Can you link this to a computer and see live images on your computer screen?

A: Yes. You would need a suitable camera, adapter and software obviously, but thats true for any telescope. A planetary camera such as ZWO will directly fit into the telescope eyepiece holder without any adapters required. A DSLR camera will need a T-adapter and mount ring for the camera make and model to fit in place of the eyepiece. If your DSLR has live view capability you can see the view without a computer. In either case you should be able to view the stream on a computer tethered via a USB cable or wirelessly if your camera supports WiFi. Im assuming you are running a compatible live view software for the camera on your computer.

Q: 7. Are there 1/4-20 holes in the dovetail so the scope can be put ton a photo tripod? What are the outside dimensions of the the Scope?
