Thanks Supernova.

I took a few pics of Neowise with my (modest) smartphone, including the glorious passing of the ISS in front of the comet. My post is in 'Observing - widefield, special events and comets. It's the one mentioning the Dordogne. I can't see how to move it here.

Nice. I'm just starting with smartphone wide-sky photos. Do you mean 'darken the sky' by using curves?

(I mean Widefield, Special Events and Comets)

See my posting in Comet section of the forum (didn't realise this section of the forum exists).

ps Sorry about the naff bottom LH corner - it's coming off!

62 years since my first telescope (a 2.5" Negretti and Zambra refractor), age has led me to abandoning telescope astronomy. But I have a new hobby - trying to take sky photos using a smartphone. So the appearance of Comet Neowise, along with a long period of clear night skies, offered a challenge. My smartphone is a Meizu Note9 - chosen because of it's camera sensor. Certainly not in the same league as the expensive smartphones, but competent nevertheless. After a few trials 17 - 18 July I took the first picture below. 20seconds at f/1.7 and ISO800. Taken with the main (back) camera of the phone - by using the 10second delay I had time to sit the phone down, leaning against the house wall. Then the heavens-above website showed that the ISS was going to be seen pretty close to the comet on 20July at a sensible time (for us it was at 23:28). Nicely dark. Two pictures, each 20sec, 1.7 and 800. First one with ISS 'passing through' Neowises' tail, second one a few seconds later - again a 20sec exposure. Lucky to have very dark and clear skies here, so I am pushing on, trying to find apps that will allow me to do intervalometer photos with long (>5second) shutter speeds. Then I might be able to stack pictures. Can anyone point me, please?
