IDAS NGS1 & Dual Narrowband by BORG 90FL

1- I got the feedback from “AstroBackyard” on IDAS NGS1.

Personally this is my most favorite broadband filter at this moment because the color balance looks as good as HEUIBII and suitable for my backyard sky glow.

See my previous write-up at

Keep in mind, this doesn’t mean NGS1 is always the best choice for all of users. Sky glow is not same. But at least I can say NGS1 is good selection to modified DSLR users who are looking for the filter which blocks the light pollution while maintaining the background color balance like HEUIBII does.

2- A serious BORG user – Steven Bellavia shared his recent dual narrowband image.

Thank you, Steven all the time.
