> HOW TO IMPROVE OUR POLAR ALIGN ACCURACY
To check the polar alignment of your telescope look trough the polar scope. When turning the Ra axis the polar star should move in the exact circle in the eyepiece without any deviation. From the Go To control panel, you can check the polar accuracy after alining the telescope by going to align – > display polar alignment. The deviation should be not more then a few minutes. You can use the menu option to correct the alignment. The telescope will point a star and then you will have to center it in the field of view by moving only the azimuth and altitude axis.
So in short : align -> polar align, you can use the the procedure for precise polar alignment. The telescope will first point the last object in the field. You will need to center it with the controls. Then the scope will point again and you will need to center the object again but this time using the azimuth and latitude axises of the head. when done the RA mount axises will point at the celestial pole and star trails during long exposures will be reduced.
Good alignment is critical for long exposure photography. Good luck!
You no more need large sensors and heavy equipment to do good general photos. The recent development of image sensors put silicon chip capabilities to it's limit by
Knowing what you are looking for is more then half way to achieving it. Breakthrough Listen is a SETI kind of project that listen for artificial signals from 1700 nearby stars up to 160 light years.
Some shots from Sofia. A very bright sky place. Zenith sky brightness info (2015): SQM 19.13 mag./arc sec2 Brightness 2.41 mcd/m2, Artif. bright. 2230 μcd/m2, Bortle class 6.
It is very important how you manage your data. So much shots, so much frames. They are full of hidden data that could be revealed later. The far we look the more we see. Each feint dot could be a galaxy far far way.
Nowadays we are so into the globalization and technologies, that I can submit observation plan to a remote, professional observatory at the other part of the word!
