In the early hours of yesterday morning (7th April) Comet 252P/Linear was still making its way through the constellation of Ophiuchus and came close to the globular star cluster M14. You can also see to the top of the image the other very faint globular star cluster NGC 6366, that lies 3 degrees southwest of M14.
There is also a wide field image where you can just make out the green colour of the comet close by the rich star fields of our Milky Way galaxy. The planets Mars and Saturn also make a lovely acute triangle with the brilliant star Antares that’s in Scorpius…so there’s a lot going on in this part of the sky at the moment :-)
Images taken with a Canon 70D camera and a Canon 70-200 mm lens set 200mm; exposure times were 45 seconds and ISO 400 at F2.8. Wide Field image taken with a 17-85mm lens at 17mm, exposure time was one and a half minutes at F5.6 and ISO 2000.
Processing Picture:
There were multiple images with dark frames stacked in DSS (Free software, Deep Sky Stacker) and processed in Photoshop… the reason for doing this is to reduce any noise (from the camera) in the pictures so you can bring out some more of the detail.
