Optolong L-eXtreme filter for Astrophotography

L-extreme Optolong

An image of the Elephant’s Trunk nebula in IC1396 taken with the Optolong L-eXtreme filter. The Optolong L-eXtreme filter for astrophotography is dual band, allowing one shot colour cameras (OSC) to capture H-alpha and Oxygen III wavelengths at the same time. I was fortunate enough to have Optolong send me an L-eXtreme filter for testing. […]

Pixinsight SHO processing of NGC 7822 – Tutorial

Pixinsight SHO processing

Hey folks! Hope all is well and you’ve been getting some clear skies. In this astrophotography video I gather data on NGC 7822 nebula region in Cepheus using my Skywatcher Esprit 100 triplet refractor telescope, Moravian 16200EC CCD and Optolong (Ha, OIII and SII) narrowband filters. It was a challenge to gather enough data for […]

Narrowband astrophotography from the city!

One of the biggest challenges in astrophotography is dealing with light pollution. This form of environmental pollution caused by unshielded and overly bright exterior lighting, washes out the night sky and makes both seeing and imaging the cosmos difficult and sometimes impossible. All is not lost though. For those of us living in a mid […]

Return to the Horsehead and Flame Nebulae

Horsehead and Flame Nebulae

It’s been quite some time since I imaged this region of space. Nearly 10 years much to my surprise as I thought about it. Returning once again to the Horsehead and Flame Nebulae, I found myself armed with a new equipment and a new set of imaging and processing skills than previous.  Imaging this deepsky […]

Running Chicken Nebula IC2944

Meet IC2944, also known as the Running Chicken Nebula. It’s a southern hemisphere deep sky object. An open cluster with an associated emission nebula found in the constellation Centaurus. Within this region of nebulosity is a set of Bok globules. They were discovered in IC 2944 by South African astronomer A. David Thackeray in 1950. These […]
