Hey I just picked up a full spectrum modified T2i for astrophotography and it can also be used for day time photos. I am wondering how to use it properly during the daytime, I see that alot of people use 560-900+ nm high pass filters on unmodded cameras but do I need to use these filters as well? I used the green grass as custom white balance and got the grass to turn a pretty cool yellowish tone but I really need to figure out how to clean up the images. They are pretty red looking and they don't look great yet. If I were to use an ir filter such as 720nm, would I still be able to shoot hand held? Thanks
