LP Filter And Photography
Good day to all
I have bought a Baader Neodymium Filter LP, I have been informed that my exposure time for astro photography has to be adjusted to accommodate the light loss.
Does anybody know of a formula that is used for this purpose, or has anyone experience with this question?
I have sorted my drift alignment, thank you for all the help, I now get +- 8 min tracking with very little drift on my eq5 mount and do 60 to 90 sec exposures without egg shape stars.
Thank you for your time and help
Andre
