Recently I have been doing some research on adding a filter to my setup to pull out some more Ha and OIII data without astro modifying my camera as well as cutting down light pollution from my suburban back yard. After many many hours of reading reviews and watching review videos I landed on the Svbony SV220 dual narrowband filter. This is a newly released filter for astrophotography so there was not a ton of “demo” pictures out there with it overall it came down to price on my end. I’ve been happy with it so far and the below is the first data collected with it.
It’s important to note that when collecting data with and without a filter that you take calibration frames with and without the filter.
