M17 – The Omega Nebula
Located in the rich star fields of the Sagittarius area of the Milky Way, the Omega Nebula is one of the brightest and most massive star-forming regions of our galaxy.
IC1318 – Butterfly Nebula (Part C)
Located in the Cygnus complex the Butterfly nebula (IC1318) is a single giant HII cloud bisected by a thick obscuring dust lane that gives the symmetry from which its popular
M16 – The Eagle Nebula
The gas columns of M16 are illuminated and eroded by the massive star cluster (NGC 6611) which is visible at the centre of the image. The cluster was born during
The Whirlpool Galaxy (M51) from Nerpio, Spain

Autoguiding with the Atik 314L+
I use an external guidescope and camera to guide the PlaneWave CDK 12.5 at AstroCamp. The initial set-up using a 60mm F/3.8 guidescope and Lodestar guider did not provide enough
Cosmic Tadpoles – IC410
Ha image of emission nebula IC410 acquired using my system at AstroCamp, Nerpio, Spain. Comparing this with the image of IC410 (below) taken using my ST-10/Megrez 120 system in Bristol
The Tadpole Nebula in Ha – IC410
Emission nebula IC 410 in the constellation of Auriga imaged in the red visible part of the electromagnetic spectrum at the hydrogen-alpha spectral line (656nm). The image shows a cloud
Active Optics guiding with SXVR-H9 monochrome camera
As of January 2013 I am now using a Starlight Xpress SXVR-H9 monochrome camera for guiding in conjunction with my Starlight Xpress Active Optics (AO) unit. The H9 camera uses
