Some New Tests Feedback about Dual Narrowband Filters 7nm SV220!

The filter is an indispensable accessory in astrophotography, and its importance is more obvious in areas with more urban light pollution. Without good filters, even if you have a very good telescope, the final captured image can be terrible.
For fans who pursue details and extreme images, good filters are worth having and looking forward to.
The SV220 is a 7nm dual narrow-band filter that we released recently, and it is also our first dual narrow-band filter. In the future, we will continue to make better filters with other specifications to meet your needs, welcome to put forward any of your ideas!
We have compiled some of the latest review images and comments about it for reference.
