While entering the world of astrophotography I was searching for the best equipment in my budget and came through an Ha filter for half the price and got it. Right now I have a stock unmodified dslr and I knew that it will be nearly impossible to get sufficient ha data using a stock dslr and a Ha/oiii filters.
So I clipped the filter on my Star Adventurer in a bortle 3/5 sky and took nearly 5 hours of data, and I was blown away by amount of data captured although having a stock dslr! Here you can see the beautiful Butterfly Nebula and crescent Nebula in their colourful outfit.
