The relentless spread of urbanisation and its associated light pollution have become a growing problem for all amateurs and astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel.
L-eNhance provides an economical and practical solution for amateurs. It is a tri-band pass filter which has been designed for DSLR (digital SLR), colour CMOS and CCD cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas.
The Optolong L-eNhance filter effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%.
The EOS-C Clip-in filter is compatible with all Canon EOS APS-C cameras except APS-S lenses.

The Major Emission Lines of Nebulae: H-α (656.3nm), H-β (486.1nm), OIII (495.9nm) and OIII (500.7nm)
The Major Emission Lines of Artificial Light Pollution: Hg / Mercury (435.8nm, 546.1nm, 577nm and 578.1nm), Na / Sodium (598nm, 589.6nm, 615.4nm and 616.1nm)
After a simple red structure transformation, the effect of SHO Hubble colour can also be simulated. Compared with the previous narrow band filters of Ha, SII and OIII, L-eNhance filter is a good substitution. So-called one filter is multi-purpose, it's worth to have ~!
Unfortunately I have not had clear skies to try it out but borrowed one off a friend to try out before buying one . I was well impressed. What I can say is I am more than happy with the service and quick turnaround I had from Firstlightoptics.Eric.
FLO always have a fast and efficient service and the Filter is awesome and not clipping any Ha on my un-modded 6D No light pollution worries anymore. Just need the Pro now for galaxies and I'm sorted.
I'm hoping for better results with my imaging, especially dso's will be clearer and less light pollution
I'm still a filter noob. Until I bought this my primary filter has been a IDAS LPS P2. I used this with DSLR and my ASI294MC-PRO. Before I talk about the L-enHance I'll briefly summarize my experiences with the IDAS to give you some context about how Broadband and tri-band filters compliment each other.The IDAS is a stunning filter - it will transformed my imaging. I consider it a good all rounder as it has produced good images of M16,M17 M27 M8 and both sides of the Veil. It didn't perform so well on the wizard and bubble nebulas. I also found that while it produced a very pretty image of the Pacman nebula it didn't capture that soft. floaty kind of image I was used to seeing on the web. I suspect this was because it's not so good a picking up the more subtle variations in the nebula. Don't get me wrong it still does an amazing job - but as you would expect broadband friendly targets are where it excels.This is why I chose to add the L-eNhance. My reasoning was simple - by letting HA & OIII (and HB) exclusively the detail I wanted would not be swamped by everything else.I have been able to use the L-enHance twice since it arrived. It delivered exactly what I wanted. The Cave Nebule has so much subtle variation that just bloomed as I processed the image. The edges and transitions are soft (in the right way) and flowing. Dark details are retained and emphasised. Everything just has more "pop". The added benefit this filter brings is it controls star brightness very well. I found I was needing to shrink far less. For this reason I look forward to revisiting the Wizard Nebula with the L-enHance.From my limited experience with the filter, I have not seen halos, star discolouration or reflections. Processing my first image was a real pleasure and had no unexpected artefacts.Optolong now produce the L-eXtreme, which does a similar job in a different way. From what I see on YouTube the eXtreme does have an edge, however it's considerably more cash. For me that means the L-eNHance remains a very viable tool and great choice for beginner/intermediate imagers who may still be expanding their kit and are looking to spread their budget.
This filter has been a total game changer for my astrophotography. My individual subs were suffering from really bad gradient due to local light pollution...well not anymore! My subs look so much better and I am producing much better quality final images as I'm not amplifying as much noise anymore. I have the clip in version for my DSLR, delivery was very quick and great service from FLO as always!
Quick delivery as always.This filter has made a big difference, I re-did the bubble nebula as I had 9 hours before hand with a different filter. I did 3 hours with this filter and it totally blew me away. I'm in a bortle 6 would definitely recommend this one.
These filters are absolutely amazing. Iíve recently switched over from a dslr to a dedicated astronomy camera and was amazed at what the camera could pull but when I put this filter on it literally blew my mind. I trained my scope onto the crescent nebula and took 30x120s now normally I was just getting the outer top edge of this nebula,with this filter and just 30 frames it pulled the whole nebula out and with some of the outer membrane stuff(technical term) my latest project is ABELLA 39 at MAG 13 I didnít think I would get much but even in the first sub I could clearly see it.. this filter is worth every penny.
This filter is a major advance in technology for astrophotographers living in light polluted skies. It enables you to take long exposure images and only lets in the light that distant nebula and galaxies emit, cutting out all the man made light like sodium street lights, security lights etc.I don't really know the technicalities of how it does this, but only know that it works and I can finally get decent images from my home in LondonHighly recommended
In the last two weeks, skies permitting, I have used this (2 inch) filter out the front where I have a wider sky view but with a couple of street lights. It has been used with an old Pentax 50mm 1.7 lens (with homemade dew shield) and Pentax gps astrotracker set at 50 second exposure on iso 6400. I would say I am no expert in astrophotography but merely someone who makes attempts with many frustrations. I am most definitely happy to have this filter - it is well worth the money. A 50mm lens is for wide images - even so I can say there is no trouble at 50 seconds in picking up Barnards Loop, M42, nebulosity to east and south of Zeta Orionis, and even The Seagull Nebula area (with a street lamp quite near). Cassiopeia, the other area I have concentrated on, from Gamma across to IC1848/1805/1795 - the nebulosity shows well along with the part of the galaxy arm in the area. This filter is a real pleasure - I just want to stay out there all night and shows great potential when I try it on a telescope at the back overlooking fields.
This is my second purchase from First Light Optics. I am truly impressed with their customer service, promptness of shipping and amazing prices. If the item is being shipped outside of the UK you will see the real price once you add it to your cart. You will be pleasantly surprised when you see the price. Of course, having the item shipped to Canada does take a few days longer and FLO is upfront with that. The product was factory sealed in a well packed box. So far, due to weather I have not used the item. Many positive comments are given by YouTube astrophotographers. Looking forward to more purchases from FLO.
