I have been asked to share some of my astro photos taken over the last 18 months, some with just my tripod mounted Canon 60D with a 200mm telephoto lens and some with this camera at primary focus on my EQ5 mounted SW 200P.
This was taken a few days after the clouded-out lunar eclipse of 21 January. I was a bit disappointed about the eclipse but I got a good shot in the end! Its a general wide angle view of the garden stacked (using simple star-trail stacking software) over 7 zoomed-in shots, taken 2.5 minutes apart, of a waning setting moon.
This is about 3 hours worth (!) of 30s exposures giving an apparent rotation of 45 degrees. This was one of my GCSE projects to evaluate the length of Earth’s sidereal day by extrapolating the measured angle of rotation and exposure time. I am still amazed at how well these shots reveal the star’s colour. I used PhotoImpression to get a negative of the image, printed it at A3 and drew construction lines from which to measure the angle of rotation. I did this with 3 separate dates to get an accurate figure. A lot of work!
The photo below is a 30s exposure of an aircraft flying left to right in front of Orion while banking away to reveal its wing lights. Taken just after a star trail session, so timing was pure luck but I have since noticed these planes always follow the same path from East Midland Airport.
Talking of Orion, this is its nebula taken through the SW 200P with a single shot of 1s exposure. The telescope’s fast F5 rating registers the faint nebulosity with quite short exposure times so the short star trails do not mess up the detail too much. Just needed some slight colour enhancement from MS Picture Manager. I must try this again with some manual tracking until I get motorised drives for the mount.
If you only have one telescope, the Skywatcher 200P, with adaptors for attaching a DSLR, has got to be high on the list.
