Very nice Paul. Looks like this setup will serve you very well. Fast scopes are a treat to use but UI am interested to know how it went from a focusing perspective. My FSQ at f5 requiures a lot of work to get focus just right and hold it there.

Great start with your new scope.

[CoolhandJo]

Thanks Doug! Yes, you are right! focusing was totally different to my f5 newt. It requires a lot more attention and seems to be a lot more temperature affected. I used a mask and had to focus twice during the session. But, I have a secondary dew heater so once I heated it up I turned down the heating a bit and it kept the temerature stable so I didnt have to refocus.

What really threw me though was my filter wheel! Half way through the imaging run a softward glitch made my filter wheel program restart. It threw out the sequence of the filters! I didnt realise until I processed the image and kept getting a green nebula! I reversed the LRGB combination and it came back to normal! So what was red was actually green! :lol:

i think its all worth it though as a faster scope makes it easier to get detail in a shorter time (allowing time to compensate for when things go wrong!)

Nice catch Paul,
I don't seem to get enough of the Trifid, nice and sharp with vibrant colours.

Hi Paul,

What a great photo.

I love the detail and the colours.

All the more impressive knowing the problems you had on Saturday night.

It was a pleasure to have met you.

Thanks.

Ross.

Hi Ross. Thanks mate! Appreciate. It was great capturing photons with you! Looking forward to the next night.

That is a great photo Paul. Love how the nebula has detail and that true gaseous look. Gotta love F4 for imaging. Look forward to seeing more!
