Despite the funky name, I'm very excited to try out this filter with my ASI294 now that the Milky Way season is starting. Several years ago, thinking that OSC cameras were going to provide very decent Narrowband images was crazy. This new crop of filters (Triad, STC Astro Duo, IDAS NB1, and now this Optolong) combined with these new color CMOS are changing the paradigm of using OSC cameras. Good times!

Awaiting for delivery and first light!

how did you manage to pre-order that?

You can do so in Agena.

Just ordered one from Agena Astro. Will be the first time using a narrowband filter!

Post your images when you get a chance!

I'll do the same. Maybe we can start a dedicated forum using this filter.

My L-eHance filter arrives tomorrow! I am planning on trying it out under the full moon.

Performance report will follow.

I gathered some data last night under a full moon 

 

I started out on Vela but I think even the moon was a bit heavy for that - it was like daylight outside

 

swopped to Carina and managed 4 hours before cloud rolled in - snow forecast today - joy 

 

data looks nice - I'll process tonight and see what it looks like - def some nice looking textures in the nebulocity so should be good

 

more later....

[elmiko]

Thanks for the report Simon. Looking forward to seeing your final image.

still lots to learn about this filter and quick a quick run through not really done much to this other than curves and some levels to go from the horrendous red stacked image to this!!

 

not sure this is the best I can get - needs more time playing with processing of this one !

 

anyway just a quick demo!

It is easy to improve this image. Take a look at the histogram of the red channel: is severely clipped. This is due to a wrong color calibration (to be specific: background neutralization). Therefore, the background looks that green.

Awesome. Can you share the capture details?

I wonder how this filter will perform at my Bortle 8 backyard?

The spectral response looks a lot like that of my OPT Triad filter.  Now that the Milky Way emission nebulae are back, you are going to love what the filter can do under heavy light pollution.
