What filters are used for Planetary photography?
Photography of planets and deepsky imaging, both are fine to use the combination of monocrom camera and filters. But slightly different, planets photography will not use what deepsky image use like Ha, Sii, Oiii filter. Planetary photography using filters often are IR, UV filters, etc.
The main aim is to capture the specific spectrum, such as rich carbon dioxide. One of the most common filter we use is IR filter-infrared filter.In nature, the longer the wavelength of light, the smaller affected by atmospheric seeing. Relatively, receiving the influence of red light, or infrared light is far less than the other bands.
Thus, when we image the planet, we usually use an IR filter, transmits only infrared, or near-infrared light, in order to reduce the negative influence of seeing.In visible light, astrophotographers use the classical RGB filters.
For Uranus and Neptune, IR685 comes first, and for Saturn, Jupiter UV/IR Cut, R, G, B are good. However, the portfolio of IRRGB is popular.

IR685 Advantage

Optolong IR Pass 685nm filter is designed to block most visible lights and can be used in IR-LRGB imaging to produce a sharper luminance image for the best planetary contrast as atmospheric seeing and distortion is much reduced at longer IR wavelengths.The advantage of the IR685 filter is to reduce the effects of atmospheric jitter.

The sensor of CCD or CMOS cameras is capable of detecting light in the 350-1100nm range including infrared wavelengths. Optolong IR685 cuts off the visible part of the spectrum and allows near infrared light to pass so that cuase the most sensitive to bad seeing is rejected. It will highly improves images on visibility, contras and details of planets and the moon. Besides, IR 685 is usually used as a key factor of portfolio IRRGB.

Imaging Target:
IR 685 is for imaging of bright planets, stars, and comet, like Uranus, Neptune, Jupiter, Saturn, Mars, Moon, etc.

UV/IR Cut, R, G,B Introduction

UV-IR cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image as most of the optics are designed for the visible spectrum, because it’s very difficult to create a lens with the same focal point for the visible and IR spectrum.

It is used on a digital camera and the video, which do not have an IR protection filter toward an image sensor or were remodeled. This is important because unfiltered CCD and CMOS sensors are extremely susceptible to UV and IR rays just outside the visible spectrum that can have a very negative impact on image quality.

Optolong LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components red, green, blue and luminance.

OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.

 RGB, parfocal:1:1:1

Creat images in their true original colors showing a wealth of natural detail;

Steep bandpass filters to eliminate UV and IR interference;

Include Luminance (UV/IR Cut), Red, Green, and Blue filters to reproduce the star's color;

Main Use and Performance

In vIsible light, astrophotographers are absolutly using the classical RGB filters. If you have Optolong LRGB filters, just try R filter for moon photography, which will be a good promotion. If you want more clear details of the Moon, then consider Optolong IR685 filter seriously.

•Suitable for color CMOS and CCD cameras.

•Use with monochrome camera for astrophotography.

•Available to assist in focusing.

•Act as an outstanding dust shield, which prevents the possibility of dust settling on the lens during long time exposure.
