Musings of astronomy... past, present and future... from the county of Pembrokeshire.
A beautiful image Mark!
Hey Pembs - Nice picture! It was pics like this that I saw in astronomy books in the mid 60's that inspired me to want to pursue the astronomical! Airy disks, diffraction from the secondary - Oh the bliss! Can you do a wide field image showing the Harp Star's much dimmer companions which no one talks about? Also RY Lyr is one of my favorite variables - wonderful "metallic copper" color just northwest of the brilliant Vega! Pic?
Great posting by the way!!!!!! I hope more folks discover you as you seem to strike the right cord every time!
Sorry - XY Lyr!OK I am done now.....
Thank You Geoff.. :0)I could quiet happily look at Vega's diffraction spikes for ages with the Tal scope..Capturing them on the camera is a bonus... :0)
Hello SUG, Thank You for your kind words.. :0)I remember most of my early astronomy knowledge came from the 60's and 70's astronomy books. One in particular I carried with me everywhere as a kid....The Observers book of Astronomy by Patrick Moore....excellent little book..No magazines then...It was not until 1980 that I saw my first Sky and Telescope magazine....That was the first time that I saw the "orange" schmidt cassegrain....No wide field is not possible at the moment. At prime focus,the Tal scope won't come to focus unless I use a X2 barlow...Perhaps if I move the primary mirror slightly up the tube I would be able to attempt prime focus without the Barlow... I have two Tal1 scopes here, maybe I can convert the second one to allow for wider fields....I'll try out different combinations with my various eyepieces and camera adapter,I might get a wider field image. If I do I'll post the results on the blog..My knowledge of variables is quiet limited, though since reading Leslie Peltier's "Starlight Night", I'm slowly developing the bug...I'll keep a look out for XY Lyra..Thanks again for the comments..:0)
