Nicely nurdled....

And thanks for reminding me that I have never tried the Whale and Hockey stick so will have to give them a go at the earliest opportunity....

Better process on it...I had 1 SII shot which has been noise reduced and comped in..

This works much better

Great image Nick. It was very clear and transparent in Hereford last night and I was able to view the Whale and the Hockey Stick in the same FOV with the 10" and the 13mm Ethos. Your photo reminded me of the view I had of the Whale last night - well not quite as good!!

See you next week.

Yep, nice image...this is on my to-do list as well but i got side tracked last night.

[MartinB]

lots of nice Ha in there. What is the thinking behind doing a tri colour narrow band?

[NickH]

Just seeing what pops out really..

I have two filter wheels, one motorized, the other not. the motorized under computer control has the NB filters in...want to get a second one so I can run any combination of LRGB/CLS/UHC and HA/HB/SII/OIII

One will have a blank space...nobody makes a 10 position wheel for sensible money so a second Atik will work the job...however right now Atik don't support two wheels on one PC...been nagging em for ages to fix it..
