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. […]

Quasi Hubble Palette processing in Pixinsight

A quasi Hubble Palette image of the Cygnus Wall in the North America Nebula. As I mentioned in a recent post, I’ve been experimenting using OSC data to recreate a Hubble palette look to my images. Normally Hubble Palette is done using a monochrome camera and individual filters, H-alpha, Oxygen III and Sulfur II. Although […]

The Cygnus Wall in NGC 7000

Starless version of Cygnus Wall image

In June 2020 I pointed the Skywatcher Esprit 100 and new QHY268C camera at the Cygnus Wall for 5 nights. We had a run of clear nights in a row and it was also around new Moon which made it even better. I was able to get 23 hours total data. This is what I captured! This is […]

IC 1805 the Heart Nebula in Hubble Palette SHO

Meet IC 1805, the Heart Nebula.  This is an image I’ve been working on for a while in the Fall here. Mostly due to weather not cooperating.   I was able to gather 21 hours of data (Hubble palette, Ha, OIII and SII narrowband) over a few clear nights in October 2019.  I processed this image, […]

NGC 281 Pacman Nebula in Hubble Palette SHO

NGC 281 pacman nebula SHO

Meet NGC 281, also known as the Pacman Nebula. Can you spot the pacman? NGC 281 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia which is rising in the NE during Fall months and high overhead in the Winter. Cassiopeia is part of the Milky […]

NGC 7822 Nebula in Hubble Palette SHO

Meet NGC 7822. This is 29 hours of data I collected over 6 clear nights. This is a Hubble palette image (false colour). NGC 7822 is a young, star-forming region in the constellation of Cepheus It lies about 3000 light years away above our galaxy. Inside this region is a supernova remnant – which indicates […]
