T - I have shot blue, red, and yellow before dropping through water. Every time you try it, you see something different. No harm in trying again, and perhaps improving.
Here also is the thing, I've already shot the blue food coloring in water as well as it can be done, or as well as it can be done by me...5 or 10 years ago for this Challenge...so I really can't do "that," again....but other people are invited to try that, it's fun...Best Wishes, Traveller (humm I've never done a yellow one!....lol)
You have to realize I find this very interesting and right down my alley. At first glance I was going to say “dang you got a scope and tracking mount” then further add “what is the NGC or M number of this deep sky object? Coordinate’s please? Paul
