LX90 UHTC 8", Baader Alan Gee Telecompressor II, ESO 1000D (modified)l, Astronomik CLS-CCD filter. 11x300s processed in IRIS. Wish I'd taken out the filter, it was dark and high and I would have got a lot more data.

Hindsight is a nuiscance, Duncan! at least you got something
Yes and even so it's better than my previous attempt at this object.
That's a good result Duncan. The Cresent is very difficult to do with wideband colour.
If you had left off the CLS filter, you would would have the same H-alpha data but the backgound would have been brighter, so the CLS filter was actually a good choice. A better choice would have been an even more severe filter.

Thanks Mark. I think it's simply a case of more data required.
