Thanks Tony
The UHCS filter really helps with the Tarantula, as it is indeed so blue on DSLR images. The blue cast I get with the UHCS filter, when I neutralise the sky background colour, makes the blue nebula much more reddish, almost like having a modified DSLR
Yes I recommend using both the MPCC and UHCS on the tarantula with your scope, stay with the high ISO of 1600, try to go 5 mins if u can, that should be good with F4.5
You will love the results.
