It was a fun session imaging The Pelican Nebula. This emission target has always escaped me and I’ve not had a good photo of it to date.
That has now changed.

Optolong L-eXtreme Review
The Optolong L-eXtreme Filter
The Optolong L-eXtreme filter is the bigger brother to the hugely popular and widely well received Optolong L-eNhance filter. The L-eXtreme is a duo-narrowband filter that lets through Hydrogen-Alpha and Oxygen-III wavelenghts.
The filter is used best on emission nebula and supernova remnants. I’ve had this filter for a while and used it between a DSLR and a dedicated astronomy camera. In this article I’ll be sharing my thoughts about this narrowband filter that was designed for use mainly with one-shot colour (OSC) cameras.

On Monday I took receipt of the new Optolong L-eXtreme Dual Narrowband Filter. This puppy lets through Hydrogen Alpha and Oxygen-III only. As luck would have it, Monday night was also clear. As was Wednesday and Thursday. So I screwed it onto my trusty Sky-Watcher Reducer Nosepiece and got ready for a night of astrophotography with this new Optolong filter.
L-eXtreme First Impressions
Like most gear, there’s a learning curve. Even a filter can take you a little bit to familiarise yourself with. As such, I chose a really easy target that absolutely lent itself to this L-eXtreme filter – NGC 6992 The Eastern Veil Nebula. This supernova remnenant primarily consists of Hydrogen Alpha and Oxygen-III. So it was the perfect candidate of low hanging fruit I wanted, in order toget used to a new filter.
