    However, last night I was able to split Rigel / STF 668. The main star is of blueish white color , no doubt.

    But what is the color of the companion ? How do you see it ?

    Last night the seeing was bad, I was able just to confirm the existance of a companion, flooded by the intense, pulsating light of the primary star.

    But in the past, in my 200mm Dobsonian, with a steady image, I saw the color of the companion as indigo.

    I would have said purple, but as I am notoriously terrible identifying colours and shades of colours, I googled indigo and I'd say you are spot on with that.

  2. The paragraph below interested me. I used to do this and then read that quite a few people leave the lens cap off so I started doing that, maybe I'll go back to cap on.

    When bringing from a cold environment to a warm environment, put lens caps on for the scope and eyepieces, and put them in their case if possible. Close the case to trap in the cold air, then bring the cases inside and let them slowly warm up over 12-24 hours. This is to prevent frost from forming on a lens surface (even on the inside of the tube

  3. Hi and welcome Pete.

    The best way to avoid GAS (gear accumulation syndrome) is to stay out of imaging, it's a rabbit hole that gets deeper and deeper 😄 Seriously though, if I were you I'd just enjoy taking my time under the stars for now, get to know the sky using a sky atlas and get to know your scope and eyepieces and every now and again just look up with your naked eye and take it all in. When I've been observing recently I've been taking little 5 or 10 minute breaks from the scope and just enjoying the stars and working out what constellations I can actually see from my back garden. So far I've been lucky to see half a dozen or so meteors in these breaks and 2 or 3 of them were really bright ones.

    Retirement is over a decade away for me, which I can hardly complain about. But working from home full time has given me a little more flexibility in the mornings and I can can do a bit of astronomy midweek.

    I started counting down at just over 10 years and now here I am with less than 4 to go, it has gone quickly, possibly too quickly now I think about it …..

  5. I have finally managed to get first light with my Vixen A80MF Achromatic Refractor and I must say I'm quite impressed 🙂 I set up on the drive which is not ideal as there are two LED streetlights, however I managed to position myself so my ever burgeoning magnolia blocked off the light from the nearest one. 

    I started off with the moon and I was blown away by how sharp the moon appeared. I started with the Morpheus 17.5mm (x52) and I could see the whole of the moon and the detail was exquisite. I followed up with the ES 14mm (x65), Morpheus 12.5mm (x73), Morpheus 9mm (x101) , ES 6.7mm (x136) and finally the Morpheus 4.5mm (x202). Views through all eyepieces were superb except the 4.5mm which I think was pushing it a bit too far. 

    I then moved onto Saturn and again I was surprised at how much detail I could see, and Titan was easily visible. With the higher power eyepieces I could see a belt quite clearly and the Cassini division. I spent a long time on Saturn.

    I then had a quick look at Albireo which didn't disappoint, pin sharp stars and when I defocussed slightly the colours stood out more. I scanned the milky way enjoying pin sharp star fields and then decided to pack up - work tomorrow 😞 

    As I was about to pack up I noticed that if I moved the scope I could just catch Jupiter above the tree opposite on the green. So I managed a quick look at Jupiter and the four Galilean moons before I packed up. All in all it was good first light and I am looking forward to using the Vixen in earnest.

  6. Great image Alan, I zoomed into the image as far as I could (500x ) to see if there were any more weird objects and I found a few more stars with 'horns'. There weren't many but interestingly they all appear on red/orange stars.

    These were on the right hand size of the image

    and these were on the left hand side

    I must say your focus must be near perfect as I zoomed in to 500x and the stars still have great shapes, I found this cute little cluster of different colours that made me smile. image.png.ff065bd76027fb9d24d1250badcfb7c6.png
