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,
I am at the moment trying to set up "Dithering" on my APT.
I am presently using a Canon 600D, with Orion ED80 Refractor, mounted on my NEQ6PRO.
Please note, I have not yet progressed to Guiding - NO GUIDING
Do I basically select "APT Dithering" and maybe leave all the other settings at Default?
Most grateful if anyone can let be know which settings I might need to adjust, and to what values.
Finding it all a little bit confusing !
Hello there! I'd like to start off by saying that I'm completely new at this so please don't get mad if I seem ignorant or don't know things. I recently came across a recommendation to go stargazing with night vision and that seemed like a really cool experience so that's why I'm here now. I wanted to ask whether it's possible to do that while spending less than $100? Obviously since I'm only getting into stargazing I wouldn't need anything too amazing, but I'm wondering whether it'd be very bad with equipment for under $100 and would it instead be better to find someone to lend from. If it is indeed possible to achieve something fairly decent for a beginner for under $100, what would be your recommendations? Thank you!
sorry I know this has been asked and I've tried getting ideas from other posts but any advice would be greatly received. My husband has always had an interest in the skies and I would love to get him a telescope for Christmas. I really had no idea how confusing it would be! I'm hugely struggling with all the types of telescopes and different peoples views.
From searching through lots of sites and reviews the skywatcher explorer and skywatcher star travel seem to be good beginner scopes. Can any advise on these or other suggestions? I don't want to spend too much more than £100 (appreciate these are both more) and I was hoping for something he can add to over time if he wishes (other lenses, phone connector etc). I would prefer it to have its own tripod though read that many of these are flimsy. We live outside of London so sky's not always great but my parents are in cornwall so hoping to view there too.
Thank you for any help
