I managed to get out under the dark sky to the village of Krepostnaya (Krasnodar Territory). Of course, the sky there is much better than in Anapa and Krasnodar. Although there are sources of light, it has become much more interesting to shoot night landscapes. The near-zenith region is especially good.
-Sigma AF 4.5mm f/2.8 EX DC HSM Circular Fisheye lens
-Canon 550Da camera
-Sky-Watcher AZ-GTi mount (EQ mode).
Single frame, 300s exp, ISO 800.
Location: Krepostnaya (Krasnodar Territory), Russia.
Also yesterday I spent the whole evening and all night looking for a program that allows converting a single frame from a circular fisheye lens into a spherical 360 panorama.
This program is Cube2DM. The program is quite easy to use, but I will try to make a video tutorial about image conversion in the future.
The result is a 360-degree panorama with “black” ground, but personally I don’t really need it, since the main thing is the sky.
Left mouse button – move the panorama
Mouse wheel or slider on the panel – scale.
I recommend expanding the panorama to full screen (button on the bottom right).
