Optolong L-eNhance Canon EOS-C Clip Filter Incoming & Special Offer

Recommended Posts

Since bringing Optolong on board the L-eNhance filter has been incredibly popular. We've have had lots of requests for a clip-in version which is now on it's way!¬†ūüôā

Due to arrive at the end of the month, there is a 'pre-order' discount available from now until the end of May saving £30.

More details on our website here: https://www.firstlightoptics.com/light-pollution-reduction-imaging/optolong-l-enhance-dual-narrowband-deep-sky-imaging-filter.html.

The L-eNhance filter is a great choice for one shot colour / DSLR imaging filtering everything apart from narrow bands of H-alpha, H-beta and Oxygen III wavelengths making it a great choice for heavily light polluted areas.

Was going to buy the IDAS D2 as my local light pollution is LED lights. Is that the better choice or would this work equally well?

This is a narrowband filter so is more suited to emission nebula targets whereas the IDAS D2 really is more for broadband targets such as galaxies. These are actully the two filters I use in my setup and I wouldnt really compare them directly- both are really great at what they do so I would recommed getting both of them- just use them for different targets.

I can't see any information about the passband widths, even on the Optolong website. Any idea of what they might be?

From a simple measuring off the screen and calculation the total pass band width measured at 50% transmittance looks around 36 nm with the Hb/OIII 24 nm and Ha 12nm. Others might have access to exact figures.

I measured about the same bandpasses when I did my review on the L-eNhance. I've also seen it cited as 10nm Ha and 30 Hb/O3 IF i recall correctly. 

 

Super good to see a clip in version. This will be immense with fast wide lenses. Guess it's just ANOTHER thing added to my ever expanding wish list

 It looks like the new Optolong L-eXtreme filter could be another very popular filter. I will certainly be joining the queue for one...

Quite interesting for my Canon L lenses, I have to admit... But first, I'll have to get a real mount/tripod.

N.F.
