Steve KnightParticipant
Paul,
Have had a Seestar for about a year, very very happy. You have to set it to save individual frames internally. FITS files are stored in its internal memory in a sub folder. If it is in station mode you navigate to it on your network and download files. You can do this as it’s acquiring data.

Steve KnightParticipantGordon, 8in and 12in Dobs on platform.

Steve KnightParticipantHi Gordon, have you thought about an equatorial tracking platform? I use mine with my 8in and 12in Dobs, set up is easy. Tracking not really good enough for deep sky imaging but fine for lunar and planetary.
Steve
Steve KnightParticipantGary,
Thanks for that. Most interesting.
It was Jeremy’s talk in June 2023 that sparked me delving into The Times archive. I wanted to see if there was any sign of John Birmingham’s lost discovery letter.Alas no.
Steve
Steve KnightParticipantMight be of interest. The Times, May 21st 1866 and February 13th 1946.
Hoping for more coverage than 1946 in 2024, or 2025 or 2026?

Steve KnightParticipantI wonder what will happen to Meade owned Coronado?
Steve KnightParticipantThanks Ian! I will give that a go.
Cheers
Steve
Steve KnightParticipantFour hours of Pallas motion from 22.39 on June 25th to 2.38 on June 26th. I trusted weather forecast and left Seestar running in the garden. T Coronae Borealis is top right.

Steve KnightParticipantAgree totally Nick. Well reputable as far as IAU is concerned!

Steve KnightParticipantBook is 2001 and by a very reputable author. Corona not bright, had to increase my cameras exposure in 2017 to capture it properly. Video best viewed with audio.
Steve KnightParticipantDominic, I did ask Alan Bean about this image in 2013. https://www.nasa.gov/image-feature/apollo-12-sees-a-solar-eclipse Forgive the name dropping! He complained how little time Mission Control gave them to get cameras ready.
Steve KnightParticipantGood point and well made Alan! 🙂
Steve KnightParticipantHi Dominic, thenks, that was very useful. After some extreme compression and cropping I managed to produce <2MB GIFs. It was a challenge but I did it! Thanks for changing the formatting on the vimeo link. I have now figured out how to do it! Steve
Steve KnightParticipantHi Dominic,
Thanks for the kind words about the videos. I have a lot more of those, just trying to extract the interesting stuff.
I have tried including a Vimeo link in the description of an image but it does not appear as a hyperlink, one has to copy and paste the URL into your browser if you want to view it.
I guess that is a necessary security feature?
Cheers
Steve
Steve KnightParticipantI was there and really enjoyed myself. Excellent talks and Nick James’s Sky Notes up to his already high standard. It was great to see everyone again. Maybe somewhere else in the Multiverse the “two ladies” are referred to as Prof Heymans and Prof Russell.
Steve KnightParticipantGreat pictures Pauline. My fat twin brother Dwight had a good time.
Steve KnightParticipantI think I got lucky, bought the 1932 edition from Amazon for £42 in January.
Steve
Steve KnightParticipantI can’t give you practical advice but I have a background with lasers. Historically many used Invar (Nickel / Iron alloy) rods for laser resonators because of low thermal coefficient of expansion. Many companies switched to carbon composites as lower CTE and much lighter. Found this paper which might be of interest. https://www.researchgate.net/publication/241529927_Long-term_and_thermal_instability_of_carboncarbon_composite
Steve KnightParticipantWell my forecast is looking good for tonight. Let’s hope no launch delays.
