I'm from Hungary. This is my first post. I am glad to be here.
Recently I'm trying to sketch some deep-sky objects. I've made this observation yesterday. Cygnus was near to the zenith and the sky was pretty dark.
NGC 7000 is one of my favourite target. I like to observe it with any telescopes, especially with RFTs and with UHC filter.
Please excuse my language errors.
Last week on august 5th we were treated to a coronal hole followed by some G1 auroral activity here in New Zealand.
Unfortunately I live a bit too far north to capture the spectacular Auroral images.
However, ever the optimist, I set my canon 6d with a Samyang 14mm lens up in my backyard and captured 300 or so shots (20 seconds at iso 3000) which I then sent through to lightroon timelapse.
I'm quite pleased with the result. Definitely some colour there.
I currently am on holiday in my father's hometown, a small island near rhodes called symi.Symj, is a pretty small town,with only about 2000 residents.That means that the light pollution levels must be low. Acknowledging that, i called my friends, grabbed my 10x50 bins(that i got for 20€ from Turkey),and went on my way to find a dark site.About after 20 mins of walking (from the city),i stumbled upon a beach, it was dark, so i went in.There i decided to lay on a sunbed that was there.After looking up(not being dark adapted, my friends just kept turning their flashlights on for some reason), i saw the haze of the milky way stretching from Cassiopeia to cygnus and beyond!I was amazed as i ve never seen the milky way before and smudged it off as clouds until i confirmed it was the milky way from an app! The weird part was that at just straight overhead, was the port ,which had many lights, and as a result the sky appeared half bright and half dark. I turned over at Sagittarius and headed over the lagoon nebula. Brilliant! 3-4 stars in a line surrounded by bright nebulosity.(while still being in the haze!) Afterwards i headed to cygnus,it was a real light show! I saw the milky way layering on top of Cygnus while catching a glimpse of m23 and yet again, failing to see NGC7000 . Then, with the corner of my eye, i detected something moving, then turned over to Cassiopeia to see a shooting stsr!(it was my first time seeing one!!!) Was very brief, yet enjoyable. Right afterwards i turned over at the Perseus double cluster.Magnificent! Appeared as 2 small balls of light , almost connected yo eachother. Finally, i realised that finally, the target i was seeking to observe all year long, M31 was into the area with the light pollution! What a shame! While also being low on the Horizon, I couldnt see it with the naked eye. I observed it with ny binoculars for 10 minutes or so . The core was resolved nicely with some hints of outer nebulosity. Overall a great night and now, i wished i had my 8" dob with me....

A series of time-lapse short videos set in different locations within South Hampshre at night. All scenes were taken between a Bortle 4-5 area, and each clip equates to 5-6 hours in real time. Please check your volume as this video contains music.
Equipment / Software:
Tokina AT-X 11mm - 20mm
Adobe Premier Pro
Alexander Blu - Background Music
Note: My first time producing a proper time-lapse video. Unfortunately the amount of noise and hot pixels were much worser than expected when I reached the video editing stage, and I need to learn how to apply darks against individual frames en masse. I am not personally satisfied with the final quality, but still thought I should share with what I have on here.
Please feel free to leave a comment, critique, suggestions and guidance on here, thanks!
I have just joined and have been looking around, and putting in various searches to find the answer to my question(s).
I have already found some valuable information, but i can't find a specific answer to a question i have relating to exposure times.
I have shot the milky way several times before, from a tripod and a wide angle lens. I am aware of and understand the "500 rule" and that worked fine for me at first when i was shooting with my Canon 6D Mark II. When i moved over to the Sony A7III i noticed significant trailing using the same rule and that led me to the NPF rule (Via the photopills app incase people dot know).
I am heading back to Tenerife once again in about 6 weeks time and want to buy a star tracker so i can get some really detailed images.
I have done a fair bit of research and in principle, the whole thing doesn't seem to be too daunting or difficult.
I have purchased the Polar Scope Align Pro app so i can align Polaris as accurately as possible, i will practise putting the unit together and familiarising myself with the different parts etc, but it is the exposure times that i do not understand.
My best glass is the Carl Ziess 50mm F/1.4 Planar, the 18mm F/2.8 Batis, the Sigma 35mm F/1.4 Art & the IRIX 15mm F/2.4 Blackstone.
I currently do not own, nor have i ever used a tracker, and I cannot find any information relating to which aperture, ISO and Shutter length any of these focal lengths should or could be shot at.
Is there anything similar to the 500 rule or NPF rule that relates to using a tracker with varied focal lengths? or is it just a case of stepping the lens down for sharpness and then trial and error?
Thanks in advance,
