Guest peepshow Posted February 1, 2014 Share Posted February 1, 2014 Imaging in the summer time is very restricted as the sun doesn't sink very far below the horizon during the night. But I would think that this also restricts narrow band imaging too. Is that true? Thanks. Link to comment Share on other sites More sharing options...
Guest CodnorPaul Posted February 1, 2014 Share Posted February 1, 2014 I'm no imager but cant see how any light would break through enough even for a camera chip - I normally stop observing May and start again in September Link to comment Share on other sites More sharing options...
Sheila Posted February 1, 2014 Share Posted February 1, 2014 did narrow band all the way through last summer, its when i got most of my images. you just have to stay up later Sheila Link to comment Share on other sites More sharing options...
Guest Kheldar Posted February 1, 2014 Share Posted February 1, 2014 (edited) It depends how "pure" you want to be Bottom line - you can image visible and nb through the summer, you're just working to a smaller window and a bluer sky Edited February 1, 2014 by Kheldar Link to comment Share on other sites More sharing options...
Guest johnrt Posted February 1, 2014 Share Posted February 1, 2014 It gets dark enough to image at the hight of summer here in Kent for 2 and a half hours a night. THe further north you go the less time you'll get. Link to comment Share on other sites More sharing options...

I can't remember what nautical gets down to in the midlands but I know astro twilight is missing in action for about two whole months Link to comment Share on other sites More sharing options...

Guest peepshow Posted February 2, 2014 Share Posted February 2, 2014 Steve, thanks for that image taken in July, but it raises another question as to what narrow band it is, and what time it was taken, please ? Link to comment Share on other sites More sharing options...
+Ibbo Posted February 2, 2014 Share Posted February 2, 2014 Sorry it does not answer your question as most of the post is not here but in an e mail to somebody else - opps If you look at my images site you will see a gap in dates around the middle of the year, except for solar I do image through that period but sometimes it will only be a few subs or even one (longer) sub that will be combined at a later date. This last year there was also a gap when I put the concrete pier in The above image is in Ha only 12nm and that is what most of my summer stuff is, I am not sure if the new 7nm will help me to image longer. at the period of longest daylight hours I will do my DSO imaging between 00-30 and 3.00 but I will push on till its almost light and discard the nosiy ones that image has 2 600 secs subs from the 30-June at 1am ish another 3 from the 6th and 4 from the 7th July there where some more taken but due to trailing were not used and the final one at 4-30 was ok for guiding but was noisy. I hope that makes more sense and is more helpful Off to correct e mail message now Steve Link to comment Share on other sites More sharing options...

I can't remember what nautical gets down to in the midlands but I know astro twilight is missing in action for about two whole months We don't loose nautical darkness here at 51.2N at all in the summer and Astro darkness only between May 25th and July 19th. But I base my 2.5 hours of imaging time on experience sitting watching subs off my camera until they become useable, and watching them out the other end become unuseable Link to comment Share on other sites More sharing options...

Sunny Phil Posted February 4, 2014 Share Posted February 4, 2014 One of the reasons I became interested in the Sun as an astronomical object is that I usually go to bed before it gets dark in summer. I'm not doing much solar imaging while the Sun is low but am checking sunspot patterns through a filtered pair of binoculars. Link to comment Share on other sites More sharing options...
Guest johnrt Posted February 4, 2014 Share Posted February 4, 2014 You lucky, lucky so and so Well I'm hoping I might get a little longer this year as I'm upgraded from 12nm to 3nm in the narrowbands! Link to comment Share on other sites More sharing options...

Richer than me too, I wussed out at 5nm Not long got them so will be first Summer this year, will be good to see how they compare with the 7nm Veil's from last year Edited February 4, 2014 by Kheldar Link to comment Share on other sites More sharing options...
