Optolong new L-Enhance NB filter for OSC camera looks promising

22 Jun, 2019 14:50
I tried the new L-Enhnace filter on my C11" with the hyperstar lens.  This filter isolates H-alpha (10nm), H-beta (24nm), and O-III (24nm) emission lines with a maximum transmission up to 90%.  This is designed to be sued with a OSC camera.   Dean from Starizona put me on to this to try in my LP area (Bortle 5).  I was anxious to try it despite poor sky conditions (below average transparency, average seeing) as Orlando weather has not been good for over a month.  I used SharpCap to do 60s stacked (about 20) captures using my ASI 385MC cooled camera.  To my surprise, I was able to get OK views of M16, M17, and M20 despite the poor conditions.  Once I have a good evening, I will post some of them.  This is an option for those in LP areas to try, especially if you do not want to buy a mono camera and multiple NB filters.  I have both and will compare them to see the difference in my area.

Bruce, that sounds quite interesting so far. I can't wait to see your images :-)

Some of my shots are with the L-eNhanced filter. I love it. I’ll probably be using it whenever I do nebulas now.

This filter does seem promising for EAA.  Just posted a couple with just a few stacked exposures over 2 minutes.  Need to keep experimenting but it does help in LP skies.
