Cornwall and Proper Dark Skies

Hello there!!

 Yeah, its been a while since my last blog post. Work and family life have been unbelievably busy these past months – added to that the summer nights being short, things on the astro front have taken a bit of a hiatus. However, the nights are slowly drawing in now, and following our recent holiday to Cornwall I am slowly getting more time to get out under the stars!

 A couple of weeks ago, we took a family holiday to Cornwall. We stayed on a working farm, on the edge of Bodmin Moor. I had done some homework, and the farm had Bortle 4 skies, compared to my 6 at home in Derby!! I was looking forward to seeing some proper skies! The first few days, while warm and sunny, moved to cloud in the evenings. However, I got my chance on the Wednesday evening – clear skies from horizon to horizon! I waited for the sky to become fully dark, and went out into the little garden we had the use of at about 10:30pm. I was lucky – the farm didn’t have any floodlighting, and the only light was a security lamp on the farmhouse. I was well hidden from it anyway in the garden.

 I wasn’t able to take my 150pl with me (too big!!), but took my Celestron 20x80’s along. After my eyes became adjusted, I was rewarded with one of the clearest and brightest skies I had seen since my days living in rural North Norfolk! The Milky way was a bright band across the sky, with Saturn nestled in it toward the horizon, and so many stars I had trouble making out the constellations! M31 was bright and clear, and Double Cluster was amazing. I spent a good half hour just sweeping my bins along the star clouds of the Milkyway.

 It was then I decided to go and get my camera, and try and my hand at some basic AP. I set up my tripod and Canon 400D, set the ISO to 1600 and opened the lens to f2.8, and pointed it at Casseopia with a 30 second exposure (couldn’t do any longer than that as I had forgotten my cable release!). The image came back and even on the LCD I could see I had captured a lot of detail! I took a few more, and the results are below.

 

Did some basic editing in CS-5 – just tried to make the detail stand out a little more. Am quiet happy with them – only 30 sec exposures! The lack of LP was a real bonus!! This has ignited my desire to take the AP further. Nothing like getting an expensive mount (yet!), but I plan to get the dual enhanced motors for my EQ3-2 and attach my camera to that. Hopefully I can get at least a couple of minutes exposures at moderate focal length. I only have a 17-55mm lens, but is the f2.8 version. I have also looked into getting an adaptor so I can attach older FD lenses to the 400D. There are some real bargains on Ebay for 135mm / 200mm and 300mm FD lenses.

 I will do a separate review of the place we stayed – it really is perfect if you are looking for base to explore Cornwall and Devon ,and also want dark skies at night!!

Thanks for reading, and hopefully, it won’t be 6 months before I post again!!

 

Cheers
