The Bubble Nebula, NGC 7635

NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, the 15 ± 5 M_☉ SAO 20575 (BD+60 2522).The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

Lunar Eclipse

Photograph taken by Bill Hughes who woke up at 2.30 am on the 28th Sep 2015 to a very misty and foggy Bessacarr.
Ever resourceful, Bill jumped in to his car and headed off to clearer skies over Wadworth to grab this amazing image of the Lunar Eclipse.
Details: 3:07am , 1/4 sec. ISO 800. with 72/432 F6 Apo refractor.

Cocoon Nebula

The Cocoon Nebula surrounded by the dark nebula Barnard 168 in Cygnus as photographed from Hatfield on 16.08.15 using a Canon600 dslr on a Takahashi 4" refractor.23x300s exposures iso800 acquired in Nebulosity, processed in AstroArt with flats and darks, were modified in Photoshop.

The North America Nebula or Water Buffalo is an emission nebula in Cygnus. The Cygnus Wall is a term for the "Central America" part and exhibits the most concentrated star forming region.Taken 27.8.15 the camera was a Canon 600 DSLR with a clip-on Ha filter on a Takahashi FSQ 106 refractor, 12x600s exposure at iso800 captured in Nebulosity, stacked in AstroArt and processed in Photoshop.

The Eastern Veil

Taken on 16.8.15, 30x300s exposures, iso 800 acquired in Nebulosity, sigma average of  2 added groups in AstroArt and processed in Photoshop. The imaging camera was a modified Canon600 DSLR attached to a Takahashi 106 FSQ. The Eastern Veil is part of a large supernova remnant in Cygnus discovered in 1784 by William Herschel.

The Eagle Nebula, taken from Hatfield on 21.7.15, with a modified Canon 600D DSLR on a Takahashi 106 refractor 13 x 300s at iso800 using Nebulosity, AstroArt cropped and modified in Photoshop. Situated in Serpens it is part of a diffuse emission nebula and contains several active star forming gas and dust regions.

Pluto

 This was taken on 7.7.15 at 1:00am. from Austerfield. Pluto is marked and near the middle of the frame. It was done during a collimation session on the ODK12, just to finish off the evening. The camera used was a Canon DSLR 550D, set at ISO800 without filters, I should have added my usual IDAS filter but it wasn't needed for collimation and I didn't add it for this.
The 15 x 60sec frames were stacked by sigma-averaging in Astroart without calibration, then finally processed in Photoshop.

M27 - the Dumbell or Apple Core nebula

Taken during a collimation session on the ODK12 on the the 6th of July 2015. I felt I'd gone as far as the conditions and eyepieces allowed on that session, and spent half an hour taking this photograph to see the result of collimation by eyepiece, on a photograph.
The camera was my Canon 550D set at ISO800. 20 frames of 60sec each, no guiding, no darks and no flats. Nor did I use my usual IDAS filter. I Sigma-added the frames in groups of 5, then averaged the 4 groups, so the result had the equivalent of 5 mins of depth. The frames were pre-processed and stacked in Astroart then finally processed in Photoshop.

Venus and Jupiter again

This one was taken by Bill Hughes from Gringley on the Hill. He used a Canon 600D with a 200mm F2.8, lens at ISO 200. It was taken on the same night and at the same time of course. Soon after that they set together. Gringley is, as the name suggests, on an isolated hill on the plain. Venus is the brighter.

Venus/Jupiter Conjunction

Taken by Robin Hodges with a Canon 7D, with a 159mm lens at f/4 for 1/20sec at ISO800. Processed in Photoshop. It was taken at 11:30pm on the 30th of June 2015, and shows the difficulty we face in Britain with light skies in summer.
