since i started wordk on my observatory there hasn't been much time for AP, but since luner photagraphy is done in minutes i had a go yesterday.
SW AZGTI with the Skymax127 and Sony A6300 and Baader Neodymium Moon & skyglow filter.
100 frames taken and 50% used to stack in autostackerd.
c925 and 294mc pro bin 1 with ir/uv cut filter. 2 panel mosaic best 25% of 1,000 . Had to convert to jpeg as i keep getting an error 200 when trying to upload a larger file. ( 50+ mb ) clicky for full rez.
and a few with the 385c camera with neodymium filter and mostly barlowed.
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,
Posting in this forum after too long!
One of the first attempts at taking photos of the moon.
All photos taken using skywatcher 90mm refractor with eq2 mount, Nikon DSLR and 2x Barlow here and there.
Basic editing in cellphone.
Thank you! Suggestions highly appreciated!
Another clear evening on Saturday near Preston, Lancashire. Although, it was pretty cold.
7 shots into this one (plus one dark), stacked within Photoshop and some level adjustments to brighten it up a little.
Camera: Canon 600D
Scope: Skywatcher 127 w/AZ-GTI mount
Shutter speed: 1/400s
