Because clouds are so unique, so is this image.

Laying back in a garden chair on a warm sunny June afternoon, I opened my eyes and this amazing cloud filled my gaze. After just a few seconds I knew I had to photograph it before it drifted away . I raced indoors and up the stairs, grabbed my old Canon 400D and ran down again. Hoping the cloud was still there and had not changed shape or disintegrated I hurriedly set the camera. I normally shoot RAW manually but I new I only had a few seconds before the cloud would be obscured by a large tree so I set the camera to AV (aperture priority mode) and chose f/10 as my aperture. I checked the auto focus and image stabilisation were on so I framed it and took the shot. At ISO 100 the camera set itself to 1/40 of a second.
So a couple of things came to mind - You never know where you next image may come from so keep a camera ready and if your in a hurry use AV mode. Because clouds are so unique, so is this image.

M10 Globular cluster in Ophiuchus

A cropped view of M10 situated some 14,300 light years away.

 Discovered on the 29th May 1764 by Charles Messier,this faint cluster (magnitude 6.6) cannot be seen by the naked eye even though its 83 million light years in diameter.
Travelling away from us at 69 kilometres per second it it lies only 16,000 light years from the centre of the our galaxy the Milky Way.

Full size image

Taken using 7 x 180 second exposures at iso800 & Canon 40D.
Sky-watcher ED80 DS pro refractor with 0.85 reducer.field flattener.
Focused using a Bahtinov mask
Heq5 pro mount guided by a Sky-watcher 80T refractor , ZWOASI120MC camera and PHD2.
Processed in Deep Sky Stacker and Photoshop CC.

This is the first time I have used the ED80 focal reducer/field flattener which improves the focal ration from f/7.5 to f/6.375. The field flattening is now very good with virtually no signs of coma (smudged stars away from the centre of the image). Nice round stars, even in the corners of the image!!!

Messier 5 Globular Cluster in Serpens

24,500 light years away, M5 contains up to 500,000 stars and is not really visible to the naked eye.

Discovered in 1702 by Gottfried Kirch, this is one of the largest clusters known at 165 light years in diameter. Its 13 billion years old. The large star in the image is called 5 Serpentis (a white giant) and is only 82.8 light years away.
This is the first guided image I have taken using my ST80 guide scope and ZWO ASI120MC guide camera using PHD2. The image contains only 6 x 3 minute subs and 9 x 30 second subs for the core of the cluster.
Darks, Flats, and Bias frames where also used in Deep Sky Stacker.
So I'm really pleased to have been guiding on my first attempt.
