Not sure where is the best forum for this question.
I like to plan shots with alignment of the sun / moon with landmarks etc. looking out to a few weeks time in July and have my eye on a shot from Richmond Park where the sun rises close to and through / over the (formerly) BT tower.
I have the ephemeris and PhotoPills mainly for Astro, I like different elements of their interfaces, together they would make the perfect app
However in this case they are giving me quite some difference in the position of the sun when it rises over the days in question. When considered from the same position in Richmond Park, I’m curious if other people have found significant differences in the apps forecast of sunrise / set time and bearing. You would think they would be consistent in how they calculate the sunrise as this is well understood. That said I realise I am looking at a very specific very narrow subject 13km away so it might just be the accepted margin of error.
It might all be moot as it will rely on clear or fairly clear skies which is a lottery ticket in the UK at the moment!!
Any thoughts welcome.
