Hi all,
I own ASI1600MC Color OSD.
And recently bought the Optolong L-eXtreme filter (the enahanced version of L-eNhance filter)

I also got a pretty good deal offer on the Optolong SHO set.
My question - do I need it for my OSC, or I better stay with the L-eXtreme filter ?

RC 8" F/8
NEQ 6 Pro

I think the SHO set is designed more for monochrome cameras

The L extreme is a better choice for most people with a one shot color camera.

 

Note that either setup is best on emission nebulae, the filters strip too much light out for broadband targets like galaxies.

Thanks !
What would be good for galaxies ? The L-Pro ?

I use nothing but gradient reduction in processing.  Any "light pollution" filter will lower your signal to noise ratio on galaxies.

 

Here's a thread where some very experienced imagers discuss the topic.  The consensus is that they've tried them, and not been happy with the results.  That's my experience also.

"Light pollution" filters don't actually filter light pollution.  They whack out parts of the spectrum, hoping that what they whack out is mostly light pollution, and what they pass contains all of the signal.  For emission nebula and metal vapor lights, that can work.  From there it's all downhill.  By the time you get to galaxies and LED lights, they're worse than useless.

Moving to Beginner and Intermediate Imaging for a better fit.
