Hi all
Did another trapezium shot this time better focus. Its very hard to guide accurately when focus and seeing is so sharp the tiniest errors show. Anyways Ive just managed to get the 2 fainter trapezium stars.
3x 10 sec ISO 200, uhcs filter used. M42 overhead, just before dark.

Thanks all
Hard to say wether an IR/UV filter would help, will try it when I get mine. Also interesting to see what the result is if no filter at all used (had the UHCS filter on at the time)
