Pelican Nebula Ionisation Front – IC5067
The Pelican Nebula is large, low-density cloud of partially ionised gas associated with the North America Nebula in the constellation Cygnus. Light from young energetic stars is slowly transforming cold

I attended an Advanced CCD Imaging Course this weekend at the Herstmonceux Science Centre in Kent. This is the former home of the Royal Greenwich Observatory. The course was held
Emission nebula in Cassiopeia – IC1795
Glowing gas and obscuring dust of the emission nebula IC1795 – part of the Heart Nebula (NGC896) – located in a complex of star forming regions at the edge of
PlaneWave CDK 12.5 operational at AstroCamp
I am just back from a four day visit to the AstroCamp observatory in the mountains of S.E. Spain where I finalised the installation of my PlaneWave CDK 12.5 telescope.

Cygnus Wall – NGC7000
The Cygnus Wall in the southern part of the North American Nebula (NGC 7000). This is an ionisation front where UV light from hot young stars is transforming the cold
Rosette Nebula – Ha|OIII Bicolour Composite
The Rosette Nebula processed using the Modified Bicolour technique for combining Ha and OIII images as described by Steve Cannistra – see www.starrywonders.com/bicolortechniquenew. The bicolour method creates a synthetic green

Dust Sculptures in the Rosette Nebula
This part of the Rosette Nebula also known as NGC 2237 contains sculpted globules of dark dust and gas that are slowly being eroded away by the energetic light and
SBIG ST-10XME with Active Optics guiding
In January 2012 I upgraded to an SBIG ST-10XME CCD camera and at the same time purchased a Starlight Xpress SXV-AO-LF active optics unit to improve guiding accuracy. The ST-10XME
Leo triplet of galaxies
The Leo Triplet is a small group of galaxies about 35 million light-years away in the constellation of Leo. This galaxy group consists of the spiral galaxies M65, M66, and
