I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope. The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera. The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured. The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope.
The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used.
My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula. I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in.
First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture.
I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try.
I welcome comments,
I have an entertaining video to share with you which is perfect for those just starting out and wanting to taste a bit of astrophotography without spending a lot of money. I image from London and managed to get a pretty good shot of Orion for just £150. This video runs through where I bought the equipment, why I bought it and how I used it to capture a Orion and some of the trials and tribulations I had to deal with on the way. Any questions please ask! Enjoy!
FYI I shot this last year but with Orion now beginning to rise over the rooftops of London I thought this would be a good time to share it.
After a lot of work and help from the great Damian Peach I managed to get some really good images of Jupiter Mars and Saturn despite a total spend of just £100... and I made another bonkers Astrobiscuit video about it which I hope you enjoy. Mr Peach really helped me pick my nights to image and the other big surprise was how good the canon 600D is at planetary. All comments/ advice/ criticisms most welcome...
