im about to purchase my first astrophotography rig and was wanting some opinions on the best method to capture subs. I’m looking at using backyard EOS on my laptop to control the DSLR, but would using a shutter release cable be better/easier?
I have an entertaining video to share with you which is perfect for those just starting out and wanting to taste a bit of astrophotography without spending a lot of money. I image from London and managed to get a pretty good shot of Orion for just £150. This video runs through where I bought the equipment, why I bought it and how I used it to capture a Orion and some of the trials and tribulations I had to deal with on the way. Any questions please ask! Enjoy!
FYI I shot this last year but with Orion now beginning to rise over the rooftops of London I thought this would be a good time to share it.
I have 7x 36mm Baader filters in my QHY Filter wheel. I use a simple Orion 80ED with a manual focuser. I have two questions basically.
a) How important is refocusing between the LRGB Ha OIII and SII filters?
b) If important, then how do I manually calculate the offset distance between them assuming the filters aren't parfocal?
