Capture Purer Nebula Light: SV220 2" Dual-Band Filter allows high transmission of OIII (500.7nm) and H-Alpha (656.3nm) nebula emission lines, while effectively blocking artificial light pollution and skyglow
Improve Image Quality: Featuring over 94% transmission and superior Out-of-band light rejection, SV220 nebula filter delivers a significant boost in image contrast and detail for deep-sky astrophotography
Capture the Cosmos Downtown; use SVBONY SV220 telescope filter to enable deep-sky photography in light-polluted cities or under a full moon
Double pair of magnets; SV226 telescope accessories compared with traditional screw rotation; magnet has stronger adsorption force; which is convenient for you to install and use
Two filter holders; SV226 telescope photography accessories compatible with 2"&1.25" filters; capable of holding two telescope filters; plug and play; reducing repeated installations in dark environments
Locking function; lock screw can adjust the tension to eliminate the gap; solve the light leaking issue under long exposure; which is a double insurance for you
وصف
SVBONY SV220 dual-band filter is designed for astrophotography of emission nebulae, planetary nebulae and supernova remnants. The 94% transmission and OD5 cut-off depth greatly enhances the contrast of image and brings out the most detailed information of those deep-sky objects.SVBONY SV220 2" narrowband filter allows OIII (500.7nm) and H-Alpha (656.3nm) nebula emission lines to be highly transparent, strongly isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue), and drastically reduces the effect of light pollution.
SV226 filter drawer adopts integrated CNC molding and anti-light leaking design. It can compatible with 1.25"&2" specifications filters on the market. Strong magnetic attraction, prevent the filter from falling off.
