12th: The 68% lit Moon occults the Pleiades open cluster as the pair rise this evening. Look to the northeast from around 20:00 UT (21:00 BST). The stars of the Pleiades will be tricky to spot when so low down. The Moon leaves the cluster around midnight.

7th: This evening sees a total lunar eclipse. This will be a tricky one as the Moon is rising from the UK as it is fully eclipsed. Look low to the east from 18:45 UT (19:45 BST). You'll need a good unobscured horizon to see it but it could make a good photo opportunity.

The method paid off though as I managed to capture some lovely Perseids this year. π
Steve Brown - astronomy and astrophotography (@sjbastro.bsky.social) reply parent
The capture rate sounds very low but photographing meteors is a numbers game. The chances of capturing a meteor in a single shot is exceedingly low. Therefore, you have to take a great many shots over the course of a night to stand a chance of capturing a meteor at all.
Steve Brown - astronomy and astrophotography (@sjbastro.bsky.social) reply parent
The drop in capture rate is likely because I took shots spanning a wider range of dates than in 2024. So, I took more shots away from the dates of highest activity, therefore skewing the results. The bright moonlight this year will have also resulted in fewer meteors captured.
Steve Brown - astronomy and astrophotography (@sjbastro.bsky.social)
My #Perseids photography summary for 2025: In nine nights of Perseid meteor shower observing this year, I took 19,317 shots and captured a grand total of 53 #Perseid meteors. A capture rate of 0.27%. That's about half the rate from 2024. π§΅ #Astronomy #Astrophotography #PerseidMeteorShower

If you haven't had enough of meteors this week, then note that the peak of the minor Kappa Cygnids meteor shower is on the 16th to 17th August. The shower isn't as prolific as the Perseids though - you'll only see one or two per hour from a dark site. #Astronomy #MeteorShower

There is going to be a few clear nights over the next week so now is a good time. However, the Moon is bright also and in a southerly direction so that will make it tricky to get Milky Way shots. Looking north for star trails around the Pole Star will have the least impact from the Moon.
