A perfect nebula filter for color cameras
For all astrophotography enthusiasts, filters are an indispensable accessory for perfect deep sky imaging.
Dedicated astronomical filters for deep sky imaging can effectively eliminate the influence of light pollution and enhance the contrast of your photographs and make targets show up more clearly and delicately.
The new 6nm Narrow Band Deep Sky Duo Filter Set from Askar, Color Magic, is a professional astrophotography tool designed specifically for deep sky imaging.
This 6nm filter set has a narrow bandwidth. So even if you are in an area affected by urban light pollution, nighttime glare and other unwanted light, you can still capture high-quality deep sky images using the Askar 6nm Narrow Bandwidth Duo Filters. The narrower bandwidth and effective light transmission greatly improve the contrast of your images, making it easier to see star details that would otherwise be quite difficult to detect.
At the same time, the Color Magic 6 nm Deep Sky Duo Narrowband Color Magic filter has very good halo control, further contributing to your astrophotography.
Askar 6 nm Narrowband Duo Filter (OIII and Ha)
The Askar 6nm Narrow Band Duo Filter (OIII & Ha) has an ultra-high transmission of over 90% at its center wavelength (500.7 nm and 656.3 nm). The Askar 6nm Narrow Band Duo filter can effectively eliminate the influence of light pollution. Even if you are in an area heavily affected by light pollution, photos taken with the Askar 6nm Duo Narrow Band Filter are still very good. You can obtain high quality astronomical images with a single Duo Narrowband filter and a normal color astronomical camera.
The Askar 6nm Duo Narrowband Filter (OIII & Ha) is ideal for photographing emission nebulae, planetary nebulae or supernova remnants, and has a very high transmission in the central wavelength. The very narrow bandwidth of the filter effectively blocks the effects of light pollution or other distracting factors such as nighttime glare.
