Title

Heart Nebula with 7nm filter

About this image

I experimented with using an external Svbony 220 7nm filter, combining the images with those taken with the built-in LP filter in Seestar S30 Pro, from my light-polluted backyard.

The OIII part of the nebula was quite vivid, and the filter cuts efficiently all light pollution. However, it lets very little light into the tiny S30 Pro and requires long exposures to reveal details. I think it will perform better on the S50.
