STAR PATH



Finally the clear skies opened up over Dorset last night. A composition that has interested me for some time is the coastal path at Durlston. I really enjoy the challenge of integrating a foreground into my night sky images.

In fact I wouldn't even call it astrophotography, the sky is a nice feature but to me its the foreground in these images that gives me the greatest satisfaction.

With haze creeping in I was limited in the amount of detail I could capture. I chose to use a common stacking method to create this image, essentially taking several images in a row and compressing them to reduce sensor noise.

A dark, dark location and last night you could hear a pin drop. The beams of light from Anvil Lighthouse peppered the sky above me and flickered across the cliff.



A surreal experience being somewhere so remote in the pitch black. Not for everyone but if you like solitude then this is just the ticket!

After Brexit, the airlines had nowhere better to go except sunny Devon. The runways weren't quite up to the same standards they'd got used to in Tenerife though.

The Integrated Flux Nebula surrounding M81 and M82

This latest process of mine from Grand Mesa Observatory was captured over 3 nights in January 2019 using the QHY367C Full Frame One Shot Color CMOS camera. Over the years I have photographed the very faint "Integrated Flux Nebulae" and "Arp's Loop" many times but I think this is quite possibly my deepest image of this area yet made possible by doing longer 10 minute exposures, also visible are the many very distant and faint galaxies.

Telescope used was the Takahashi FSQ 130 F5 APO Refractor “System 1” on Grand Mesa Observatory’s January subscriptions. grandmesaobservatory.com/equipment




Total Integration Time 11.5 hours
