IDAS Nebula Booster Filter - 48mm

A Nebula Booster Filter - 48 mm (2-Inch):

This new nebula filter is permeable to the spectral lines H-beta, Oiii, H-alpha, and Sii - and with very high transmission. This makes it ideal for the photography of large fog areas, in which it lets pass the typical colors of these objects and blocks the disturbing sky illumination.

In particular, the filter quickly cuts off the near infrared, all the way up to 1100 nanometers. This is important because cameras are sensitive to this area, but the telescope optics are optimized for the visible spectral range and faulty in the infrared range. The Nebula Booster is particularly suitable for fast lens optics , as they are preferred for the astrophotography of large fields. The filter glasses are 2.5 millimeters thick. It can therefore be exchanged with other 2.5 mm thick IDAS filters without changing the focus position.

 

Image Note: This is for the 48 mm filter only, the 52 mm filter is shown for size comparison and availability.

Must Have for Suburban to Urban imaging with an OSC

I've been using this filter through the Summer and I'm very impressed. The filter itself is very well made and solid. I received it quickly and packaged well. I image in Bortle 8/9 skies just outside Chicago, and had been using a CLS filter. The entire background would blow out with any exposures over 3 minutes. With this filter, I've done up to 7 minute exposures and I'm not even close to half way on the histogram (using ZWO ASI071MC Pro at unity gain). I don't think I've really even hit the sweet spot yet. Straight narrowband imaging isn't an option for me, and the high-end quad band filters are out of my price-range right now, so this was a great option for me. I also had an opportunity to briefly use this filter in Bortle 3 skies on the East Veil and the vividness of the blues on a single 4 minute exposure was unlike anything I'd been able to achieve before. I'm anxiously awaiting all the red fuzzies in and around Orion, where this filter should really shine. Image examples @katorellaastro on Instagram.
