> A dream come true
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!
Yes I can image the southern sky with a "telescope hosting" at Chile. This country is astronomer's dream as we have there mountain and desert with perfect dark sky and seeing conditions. I recently use El Sauce observatory trough telescope.live.
It was challenging and exiting to plan observation at souther hemisphere and then process real professional data in FITS format (by the way I do not like it as it is hard to
extract all the dynamic range from it. There is not so much good software that reads it).
The target I submited is very special for me. It is the minor planet Gabrovo (2206 Gabrova), named to my home town and discovered in 1976 by Nikolay Chernih.
I actually try to shoot it with my telescope but failed to recognise it (it turns out later that it was actually on the image), so I use the 60cm RC telescope of El Sauce observatory.
This a great step towards my scientific explorations. Thank you Galactic Hunter for letting me know for this platform :)

And here it is the first digital image of 2206 Gabrova
Witch is better. Stack or long exposure? It depends…
NGC 7000, South America nebula in Cygnus, taken by me from NAO Rozhen. 2 shots composed by 45 frames @ 30s, ISO 51200 with SW 200pds and Pentax k-5. Same processing with DeepSky Stacker and LightRoom.
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.
Removing the DSLR build in IR-cut filter will give you at least 50% more sensitivity for hydrogen alpha emissions of the nebulas. Also the camera will be more light sensitive at dark allowing you to shoot more faint objects.
We can check what is like to process day shot with similar to astrophotography techniques. It is cloudy in Bulgaria for the next week or so and I took shots of the nearby mountain trough the fog with 200mm lens.
