#20: M81 and M82
16.02.2019 New aspect: Stay long on two galaxies Image acquisition: This time I wanted to capture tow cool galaxies in one frame. I searched Stellarium the day before and found those two beautiful galaxies. They fit into the FOV of my camera/scope as I use an old Olympus E510 and a Skywatcher 150/750 Newtonian reflector. …
#19: Visual observation of M42 Orion Nebula

#18: Jupiter and Venus
23.01.2019 New aspect: Taking an image of Jupiter Image acquisition: I took video files of both planets on the morning of the 23th of January. It was a Wednesday so I was (again) in a hurry. Setting up the scope was not that hard but keeping the last trouble with the moving Venus in mind …
#17: Return to M42 Orion Nebula
02.01.2019 New aspect: Return to M42 to gather more data Image acquisition: This time I had one target and one target only in mind (finally managed to obey my own rule!): M42. The last session gave me 32x1min light frames to work with and hence a lot of noise in the image. After setting up …

On morning the 5th of December I set up the scope in a hurry to capture Venus. Polar alignment, balancing: All quick and dirty because of the limited amount of time. The …
#15: Dancing Moon and Venus
04.12.2018 Description: The image was taken at dawn right before sunrise. Moon was three quarters on its way to new moon and Venus was very very bright standing next to the Moon. Because sunrise was close the dark side of the moon was lit enough to see some details. Catching both the bright and the …

17.11.2018 New aspect: Taking the first close up surface images of the moon with a modded Logitech webcam Image acquisition: When imaging the Mars with the modded webcam in the last session I recognised just how hard it is to get the focus right. So a member of a astro forum (Hi Carole!) pointed me …
