  1. Orion splendid over our backyard!

  2. 70 years old today and I remain unsure as to what I want to be when I grow up.

      Congratulations on the big 7-0! A piece of advice - NEVER GROW UP

      Happy Birthday and I hope you had a good one :smiley:

      Like the question 'what do you do?' the other 'what do you want to be?' has always bemused me. They're lifeless questions rooting for lifeless answers.

      Happy Birthday! What’s this growing up thing about then 🤔😂

  3. A very generous and exciting proposal. As I have decreasing mobility and in the week of my 70th birthday, it struck me that the number of times I will be able to lift my 5inch refractor out of the house and onto its pier mount are decreasing each and every year and not only due to the appalling weather here on the east coast. Thank you very much FLO you are a class act and will now keep me astronomy active long after my telescope toting days are behind me. Best regards from George in Lowestoft
  4. Hi and welcome to SGL from George next the sea in Lowestoft.
  5. In between the clouds, rain and moonlight I managed to capture about an hour of 1 minute exposures at ISO 800. with my Canon 600d DSLR and EF zoom lens 90-300. all mounted on a Star Adventurer. I thought I would get my last gasp glimpse of the summer 'Swan' before I start hitting the 'Gluhwein'. Added a pretend diffraction spike to Deneb for fun!
  6. The above image created from the SDO 'Sun Today' (composite 171,211 and 304 angstrom filters) Credit for base data "Courtesy of NASA/SDO and the AIA, EVE, and HMI science teams." I really like this image as it appears to show Mercury within the corona.

  8. This isn't a brilliant image of the transit of Mercury 11-11-2019 but the weather was terrible. This image was taken between clouds just before sunset with a white light filter and my Altair Astro 66mm doublet with 2.5x Barlow and Canon 600d DSLR. The unusual bit being, it was taken by me hand holding this ungainly telescopic lens combo whilst leaning, well past my natural angle of repose and well outside my first floor bedroom window.
  9. Funny sort of night here on the east coast. Too much moonlight, too much cloud, fireworks and then rain. In between I captured a few widefield snaps of ngc7000. Unfortunately my dslr, intervalometer and staradventurer mount were rained upon when a sudden 'squall' took me by surprise and terminated my imaging session. Have dried everything and all appears well with my kit. An Intervaluometer can get the unwary astronomer into 'cold' water!

    Night night stargazers hope your evening went better.

  10. Tonight the sky is clear and velvet black here on the East Coast. Haven't set up the gear tonight as I have a long car journey tomorrow and I need some sleep. 

    Just went outside and looked up. Pegasus and M31 visible to the naked eye and almost straight overhead. The Milky Way stretched clear across the sky and disappeared with Cygnus to the west. 

    As I turned to look towards the Pleiades, a really bright and red coloured Orionid meteor flamed across the sky below the square of Pegasus. What a beautiful and wonderful thing to witness on a cool autumnal night!

  11. Grim weather here on the UK's east coast. Last night I noticed that upper atmosphere ice crystals had given the full Moon a '22 degree halo' Snapped this with a hand held Canon IXUS 160 compact camera. - Even optical artefacts may be beautiful.
  12. My old architectural practice was multidisciplinary (including mechanical, electrical and environmental engineers) and we designed a number of archive facilities which had strict environmental controls regarding relative humidity and temperature. I have some experience , some success and more than a few set backs in battles with condensation. The key issues are the relative humidity of the air and the surface temperature of your kit. In my backyard where I observe the relative humidity is often somewhere between 85 and 95% at this time of year. As soon as I take out my scope or cameras they start to radiate heat out into space. At some point in time the glass will cool and reach the dew point (the temperature at which the moisture in the air can no longer exist as a vapour). Irrespective of the amount of thermal insulation or the thermal mass of the glass at some point in time the dew point will be reached and condensate will appear where I don't want it. Thermal collars and the like which I have made delay the inevitable for about a hour and a half for the smaller bits of glass (camera lenses, my 66mm refractor and 60mm guide scope) and approximately 3 to four hours for my 127mm refractor's objective lens. The only way to prevent this happening is to add back the heat (that is being lost through radiation out into space) either by using a hair drier or dew heaters. For this reason I have just made dew heaters for all my bits of kit as I got fed up with having to stop imaging on the few clear moonless nights available because 'Niagara Falls' had turned points of starlight into fuzz balls. I suspect your 'observatory enclosure' will increase the time before the dew point is reached but if the relative humidity of the air in the observatory is high and in reality it will be similar to ambient external RH, condensation will eventually form on bits of kit that have a surface temperatures equal or lower than the dew point temperature. I've rambled on for a bit - sorry - old consultants never die they just ramble on for a bit more. best regards from George 'moist' in Lowestoft next the Sea.
  13. Today, I completed my last 'dew zapper' and fitted it to my 127mm. Meade 500. I'm awaiting some bell wire and a 1 amp-9 volt transformer from the 'bay'. When all connected up I shall be ready for 'astro fun and games' throughout a cold and moist winter on the East Coast. 

    I currently have a few stars outside but Metcheck doesn't look encouraging. Think I will stick with binoculars tonight.

    Night all

  14. We had the electrical storm directly overhead in Lowestoft. A second after a tremendous lightning flash the Sun from the West created a wonderfully bright rainbow in contrast with the black 'back-lit' clouds in the East. Spectacular! I do hope you are all safe in your tents at Kelling? best regards George
  15. Nicely bonkers mate! I manage to fill my 'down time' with similar eccentricities and my wife has been used to it for forty-six years, you have to admire their fortitude! best regards from George In Lowestoft
  16. Hi Gina It's raining on one side of my house whilst I have bright sunshine on the other and I don't have a big house! I can be simultaneously optimistic and pessimistic - the wonders of living next the sea. regards George 'damp in Lowestoft'

    As Jupiter this year, never got high enough for me to point my pier mounted scope at it, I was delighted to find out that I could 'play' with Juno Cam images. I thought this image really shows the GRS 'unravelling' at the edges. Credit: NASA JUNO.
