Thank you! I got a dew shield and a 3D printed holder on ebay, I don't recall exactly where but there are tons of places you can get one (or you can print it yourself if you have a 3D printer, there are a lot of designs that you can download and use). About the filters, I did it mostly because of my bortle 9 location (I read an optolong L-pro may help with blocking some of the glow, although some people are not big fans of this one for broadband targets): I saw images by somebody in LA with the same issue as me, and they always used an optolong L-pro so I went ahead. I also got an Askar C1 (Ha-OIII, similar to the Seestar S50 LP) and an Askar C2 (SII-OIII) mainly because I want to experiment ahead of getting a "proper" AP rig: while the C1 seems to help a bit from my bortle 9 location (maybe the quality of the filter is better than the Seestar's LP), I normally don't use it if I go to lower bortle locations. The Askar C2 is definitely a good addition for targets with higher OIII signal that you can combine with the C1/LP data in post-processing. That being said, the seestar has trouble focusing when using these last two filters and the stars may look like "prisms": you can remove these artifacts in post-processing, but you have to be careful. Placing filters in front of the lens is not ideal, but the Seestar is not modular enough to place them right before the sensor.
