M16



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.



M27

The Apple Core or Dumbbell  planetary nebula in Vulpecula was taken with a modified Canon EOS600 on a Takahashi 106 refractor. About 2 hours worth of 120s exposures at iso800 with flats and darks were acquired in Nebulosity, stacked in AstroArt and modified in PhotoShop 

M56

Taken with a partly collimated ODK12 and my M25C, on 6.6.15. An exposure of 30 x 60sec without flats or guiding. More work needed on collimating and mirror distance too, but improving well. I'm hoping to get stars to be the size of those seen by my Tak 106 but keep forgetting that the ODK12 has a focal length 4 times that of the Tak. Stacked by sigma averaging in 10s then adding the three averaged sets. I also need to aim more carefully. All done during the collimating process.

Orion Widefield Nebulosity


This photo was taken by Bill Hughes with a Canon 600D DSLR using an 80 mm f1.4 lens set at f2.0, complete with CLS filter and at ISO 3200,  only 5 exps x 176 secs each and Stacked by sigma average. 
An incredible amount of nebulosity is shown in this image and you can even clearly see the Horse Head Nebula just below Alnitak in Orion's belt.


 Taken in Tenerife on the 16th Feb 2015.

M13

Using Nebulosity, AstroArt and photoshop this is a combined image of The Great Globular Cluster in Hercules taken with a Canon 600 dslr on a Takahashi106 refractor.The 12x300s.iso800 and 45x120s,iso400 exposures were taken on the 10 and 26.4.15 respectively.

The Owl Nebula and M108


The Owl is a planetary nebula in our galaxy some 3000 light years away. M108, an  edge on spiral galaxy, is further away at 45 million light years.This photograph was taken with a CanonEOS600 on a Takahashi106 and is a composite of 19x300s exposures, iso800 captured in Nebulosity,calibrated with flats and darks in AstroArt and finally processed in Photoshop.
