SV220 1.25 inches Dual-Band Nebula Telescope Filter for Astrophotography
The filter is suitable for those astronomers who are already imaging using color cameras, and don't want to transition to a monochrome camera set. Be the efficient astronomer with SV220 Dual Band Filters.
This SV220 telescope filter is also a fantastic solution to dealing with light pollution that is becoming more and more prevalent.
The filter has relatively wide bandpasses, especially at the OIII wavelength (500.7nm width).

Fantastic filter, I attach an image of the Elephant Trunk taken with an almost full moon, 50 minutes.

I had this filter for more than a year, it was the best investment i made in my astro journey. It feels like cheating when imaging emission nebulae. Results are super fast because this filter doesnt allow moon light or light pollution to come through so you can even image at full moon days.

I've been using 1.25 version clipped into a Canon DSLR (stock and later astro modified), and I have to say that the results wowed me. I did a few sessions with M42 Orion Nebula, Jellyfish Nebula, Rosette Nebula last winter/spring and the amount of details and how much of extra "clouds" you get, comparing to the DSLR on its own, or with CLS filter is huge. Light pollution does not exist for this filter. Packaging is good, filter is safe in the box and padding, cannot complain. I'd highly recommend.

I own the SV220 and it is the wonders for my imaging!!! Of course I'm new and haven't experienced anything else but for a first time experience as I'm trying to figure out how to do this hobby it's been great...

When I got an OSC, I wanted to get a DNB filter for nebulae, and I'm not disappointed. I get quite strong halos when I attach the SV220 to the nosepiece of the 705, but all I do is move it to the front of the focal reducer in my SV503 80mm, and that sorts out the halo completely. I should have gone for the 2" because it would fit easier, but the fact is that I can get it on there and it's working just fine.

It arrived in good condition, it is only necessary to try it and we will see how its performance is, I really liked that it was very well packed and protected, the case is different from what normally come svbony filters, this one is better feel more protected

Features
1. Reduce light pollution; SV220 telescope filter can greatly reduce the interference from natural light sources such as moonlight or artificial light pollution such as street lighting
2. Astrophotographic;the filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; the filter allows high-contrast imaging even in areas with strong light pollution
3. Wide range of application; the 1.25 inch dual band filter can be used with most cameras and filter wheels; no worry about not applicable
4. Improving contrast; an increase in contrast can be perceived as an increase in brightness; the filter makes the contrast of the nebula and sky background increase; not the nebula brighter
5. Strong applicability; the filter applicable to SVBONY's electronic cameras and astronomical cameras which the apertures are 1.25-inch; but for the different telescopes and cameras; the installation order of filters is also different
6. Easy to use; the dual-band filter makes it possible to simplify and decrease the difficulty and cumbersomeness of post-processing for users
7. Standard 1.25 inch size; the 1.25 inch size of the filter fits most telescope; and the weight is 5.4g; its central wave length reach 500.7nm
