    Heads up ! Starcount !

    Very milky skies here tonight. I can only see 4 of the lttle dipper and only 17 in Orion. Trying to image the Witches Head, but I'm fearing that it is too faint a target to get much in these skies, though it is just visible in stretched 10 min L subs.

    Superb work Carole, it really shows what skill and perseverance can achieve from even the most challenging light polluted locations. Geof

    Absolutely, though I think it's ok to confirm very faint stars with binos, just to be sure that your eyes aren't deceiving you. Geof

    SGPro not slewing after plate solve

    I also use PS2 with local ANSVR for blind solve as backup if the initial slew is too far off for PS2, which is rare, but happens sometimes. I also have my pointing accuracy set to 5px which is close enough for me. I'm guessing that you don't want to be too optimistic with this setting if your mount isn't capable of very accurate pointing, as you could just keep going round in a loop until you've used all attempts and it 'fails', plus I dither so the images move around once I start capturing anyway. Given that your initial slew is a few hundred pixels out and then never corrects, I'm wondering whether the command to slew after solve is working at all. You could try nudging the mount further away and then solving again to see if the mount then moves at all. Geof

    I'm sure. When I was about 10 years old (that's some 55 years ago), living in North Norfolk, I recall that my best effort was counting 17 naked eye stars in the Pleiades - now I'm luck to count 7...!! The skies are nowhere as pristine and my eyes are even worse, especially having to look through my specs....!!

    Heads up ! Starcount !

    That's pretty much what I've been getting excluding the 4 corner stars, but that was before the survey started and tonight I have 0 stars.....!!

    Heads up ! Starcount !

    As I understand it you DO NOT include the 4 corner stars, clockwise Belelgeuse, Belatrix, Rigel and Saiph. This is from the BAA website... Hope this helps. Geof

    I've been clouded out all night, but an astro friend in west Norfolk about 30 miles away has had pristine skies... . Theres a continuous band of rain cloud moving due south off the North Sea that won't leave me alone

    As well as submitting your star count to BAA/CPRE, this is also a useful resource (both to use and to submit) as it shows how many stars you should be able to see at each magnitude range. https://www.globeatnight.org/webapp/ Your 12 stars suggests somewhere in the mag 4-5 range, which I think is consistent with your sqm reading and Bortle 6-7.

    Saturn between 2009 & 2018

    Well that is a suberb collection of images showing Saturn's changing tilt over decade. Love it. Geof
  11. Wow Dave, that's really colourful. I can never get colours like that in my stars - how do you do it?
  12. That's a really nice result Dave. I keep thinking that I should buy something like a 24mm, or 35mm lens for my astro-modified Canon 600D to shoot really widefield targets like that. I have a Nikkor 18-200mm zoom, but my Nikon DSLR isn't astro-modified, so not sure how well that would work on Ha rich targets like Orion - maybe I should try it at 18mm as an experiment.... Cheers, Geof

    Aurora in Scotland

    Also as confirmed by email just received from the BAA Aurora and NLC director.... Aurora Alert A coronal hole impact started to hit Earth yesterday at 22.00UT 30th January 2019. Wind speeds are now at 520kps as of 22.00 31st January and it has reached a level 6 triggering a G1 storm. I have had sightings between cloud up to 30degrees high. It should be visible to as far south as northern England and could go further, and it has been seen as far south as Dundee.
