As you could see in my video I have Dobsonian mount so I cannot perform longer exposures than 25 seconds. Every longer one captures star trails. Presently, with the derotator, I am able to leave my camera set up for thousand pictures and go home to watch TV or movie. The only problem is that my drives have strange small movements invisible without capturing the pictures. Short exposures like 5 or 10 seconds show nothing, stars are simply points. But longer ones make patterns like butterfly., so I think the error is looped. I ordered better quality stepper motor drives and want to replace them and check. If that is OK, I want to play with astro-photography. My F5 scope and IDAS LPS-D2 filter (which I gonna buy) can do it even in Liverpool

Hi, I'd like to show my setup in the last action. Regards, Tomasz

Good morning After many months of theoretical preparation, and then the practical ones, I have finished work on my own field derotator. As usually, I would like to share the effect of this big project making a video-report in YouTube. I invite you to watch. Best regards, Tomasz

Hi, After quite long lack of activity here I'd like to present an another point of view about the Creation of the Universe. Simply watch the video... https://youtu.be/yKsO2Tf5TW4 🙃 Regards, Vroobel

I'd like to do first steps towards an early morning observation, maybe also simple astro-photo. I see main benefit related with better seeing in comparison with evening, when air is warmer and unstable after the day. But how to prepare for that? I expect a dew, so shouldn't do it without system of heaters. I work on that together with my friend. How do you prepare your stuff, do you set it up in evening and wait for the morning, or before the observation? Can you give me some advises? I have other questions, but they depend on answer for the first one. Tomasz
