A few days ago I asked about astrophotography (First astro opportunity (photo club outing)). Well, I did make some mistakes (long exposure noise reduction was on, whereas I should have just gathered more light in the same time, and used dark frames in Siril), but it was a very nice experience.
These are with the phone:
A 800 and a 1000 mm telescope, with filters mounted, to observe sunspots and flares (Hydrogen Alpha, red filter):
The sunspots and the flares, simply by holding the phone to the respective eyepiece. At first, when I looked into the telescope showing the spots, I thought something was wrong, and I was just looking into an empty viewfinder, with some dust. Then it hit me: it really was the Sun. I cannot explain why, but it was a very emotional moment. I mean, I have seen great, high quality, high resolution photos and videos, but seeing it with my own eyes was simply somehow different.
The big telescopes. Their description says me little, but I do understand they have 80 cm and 55 cm mirrors, with 7.8 m and 2.5 or 10-15 m focal lengths, respectively.
The 85’er is a pure Cassegrain telescope with a focal length of 7.8 m. The other telescope can be converted from Cassegrain to Newton configuration. Focal lengths of 10 to 15 m (Cassegrain) and 2.5 m (Newton) are achieved here.
Our guide and a few club members next to one of the smaller devices (Ritchey Chrétien-Astrograf (Pro RC 360) by Officina Stellare).
And the big ones in action:
Finally, ‘my’ shot of the day (night). Not really mine, as I was just following instructions like ‘attach your camera here’, ‘adjust the focus here’, ‘good, now take a picture’.
