A Brief Bubble

[tomato]

After a very frustrating period (set up four times based on a consensus of promising forecasts, only to be thwarted by clouds every time), I managed to get 75 mins Ha on this object  before the object was lost behind my front porch. It’s as grainy as hell, but that’s what I get with such a meagre integration time.

Is the bubble supposed to be spherical? It looks decidedly eggy in this shot.

Thank for looking.

That’s looking good. How many subs do you have for your 75mins? Noise will certainly ebb away as you add more subs. The question always becomes which will win in the trade off between sub number vs sub length; is it better to go for longer subs and perhaps deeper data or shorter subs so you have more of them to eliminate the noise, but at the cost of detail? Oh how we love a quandary!

As for the eggy Bubble, definitely not perfectly spherical and exactly as your image shows, slightly elongated and ovoid.

Thank you PhotoGav,

I currently take 15 minute subs with the Ha filter, I could probably go to 20 minutes without a problem, I just need more time to experiment. Needless to say, my move to a permenant observatory is eagerly anticipated.

That’s lovely. A great result for 75 minutes. As gav says the bubble looks eggy alright!

Very nice - like the composition

I feel your pain but a great result

Looks the right shape to me! Well captured despite the low integration time.

Thank you all,

I am really looking forward to the time when I can post some results with integration times measured in hours rather than minutes.

As Wing Man via Teamviewer I know the effort Tomato puts into these images. I learn something from every session!

Well Done
