This 4-stop, 82mm NiSi Nano Soft-Edge Graduated IRND Filter helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. The design of this filter incorporates a rotating mount to allow for precise positioning of the gradation along the horizon line. Neutral density filters do not affect the coloration of the image and the density provides up to a 4-stop reduction in light from entering the lens.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces. The Nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

This NiSi 82mm Nano Soft-Edge Graduated IRND 1.2 Filter is constructed from H-K9L optical glass for increased clarity as well as color fidelity.

Q: 1. How long does the battery last with the 6k Pro?

A: Around 2-3 hours.

Q: 2. How many mirrorless cameras and monitors could be powered with one battery? Will one battery handle 2 GH5 cameras with x2 on camera 5" Feelworld monitors? (D-tap to monitor than from monitor to dummy GH5 battery)

A: This battery has these outputs: 2 x D-Tap - 2 x USB Type-A. Anything beyond these options would be more than the battery can handle.

Q: 3. Does anyone have an adapter for the feiyu ak4000 gimbal?

A: We are not aware of a similar adapter that is available for the Ak4000.

Q: 4. There are two D-Tap connectors. One labeled PTap and the other SMARTAP. Which do I use with the supplied AC adapter for charging and does it matter which I use to power cameras?

A: For charging the battery you would use the standard D-Tap Connection. For powering a camera you can use either of the D-Tap or the SmartTap, however the SmartTap offers the ability to communicate SMBUS/smart battery data to compatible cameras.

Q: 5. This charger has the option to charge at .25 A or .5 A does it matter which one I switch to charge my nucleus nano batteries?

A: We would tend to imagine that the .25a charge is slower than the .5a charge.

Q: 6. Will this bag work for a Celestron Nexstar 4SE telescope?

A: No, I am sorry the Celestron Soft Telescope Bag (40") will not accommodate a Celestron Nexstar 4SE telescope. A better choice would be the Celestron Carrying Case for 4/5/6" NexStar Telescope B&H # CECNS4580TAS MFR # 94003.

Q: 7. How do I know when the battery is charged and how long does it take?

A: There is an LED indicator, usually green means it's fully charged. It should take around 36 minutes.

Q: 8. I have the celestron heavy duty tripod#93493. Can I use this bag for it?

A: Yes, the Celestron Heavy Duty Tripod for CPC, Nextar GPS (MFR #93493) will fit in the Celestron Soft Tripod Bag (34").

Q: 9. Can i power the blackmagic 12hdr 7inch video assist with this battery?

A: Yes, you can use a D-tap to Sony L-series dummy battery cable.

Q: 10. When charging, what is the difference between flashing red and solid red on the LED indicator?

A: The Tilta Nucleus-Nano 14500 Battery Charger III (B&H# TIWLCT04BC3) will have a flashing LED when it is charging the battery. When that LED becomes solid (i.e. constant) then the battery is fully charged.
