Thinking of trying one of these with my ASI071 OSC camera. Transmission and bandpass specs look pretty similar and I have read good reports on each one. Any thoughts on which one may perform better in medium light polluted skies or is it pretty much a tie?

 

 

Thanks...John

I think Optolong created the L-Enhance as a direct competitor to SCT's Duo to catch some of the fanfare from the Duo.    Specs look about identical.

I got the Optolong but only tried it one evening so far due to bad weather.  I was still impressed given the poor transparency/average seeing that night in my Bortle 5 area.  Dean from Starizona was a tester and swears by it... which convinced me to get it.  There are good examples on Astrobin of both being used.  They seem to produce similar results based on my eyesight and the Optolong version is cheaper.  So, no reason for me to get both and compare.

I wasn’t interested in the STC duo due to many images with very pronounced star halos. After a quick look at the new optolong filter it appears that the halos are minimal at worst. For the relatively low price I’ll probably try one.

This image was captured using the new Optolong L-eHance filter. If anything it really helped to reduce the stars.

Hi,

this is the first image captured by mean of my ZWO ASI 071 color camera, using a narrowband filter (Optolong L-enhance) and a Taka baby refractor (FSQ85ED). The image has been taken in a medium pollution location, 4-5 Bortle scale. The total acquisition time is 6300 s. The image has been post-processed by mean of Pixinsight.

Hi,

another example of use of the Optolong L-enhance filter, under the same conditions described in the previous post. The target is NGC 6888, with 7200s acquisition time.

I think I'm going to pick up the L-enhance for Summertime nebulae. It's on sale at OPT and it puts up some pretty nice results.
