    Hi Victor,

    thank you very much for your beautiful reports - very nice pics, cool choice of objects, what a work to make that kind of presentation!

    I have not read everything yet, there are a lot of cloudy nights ahead for that ;-)

    But one thing: Andromeda´s parachute: your magnification has been too low! At powers around 500x the elongation comes within reach, better at 700x. Even 1 or two very very elusive stellar condensations can occur then - even in 12".

    CS!

    I realise that... and I will definitely re-attempt asap.

    On that note: thank you for your comments! Much appreciated. I may be able to post the fourth and final blog of the trip in the coming week. After that, it's perfecting the timelapses and compiling everything to a decent tune.

    Cheers,


    Victor

    Wonderful blog posts Victor, and I’m so glad you were inspired to observe the Cygnus Loop because of my S&T article. You had some great observing nights, and sharing them with us in such detail is a gift - thank you!

    Thank you for your kind words, Howard! Hopefully another trip is possible mid-winter or early spring. I must say that writing a blog about deep sky observing, for which I must travel, is a lot more fun than backyard double star sessions..!
