NGC1232 Revisited - now 3h40m

[Screwdriverone]

Hi All,

I added another hour and a 40 mins of data captured on the 6th January to the 2 hours I captured on the 28th December, seems to have brought out some more details and reduced the noise somewhat. Total exposure time is now up to 3 hours and 40 minutes, making this my longest exposure on a single object to date. Slightly cropped to remove some of the stacking artifacts caused by the two sets of data not being exactly in the same FOV.

Stacked in DSS, processed in Nebulosity and Startools.

More data, must have more data ;)

Hope you like it.

Cheers

Looking good Chris.

You're producing some very nice photos despite the dirty Sydney skies.

Thank you Ross,

Yes, the skies are shocking in Summer, the seeing is yuck and there is a lot of thermal noise for want of a better word, maybe sludge sums it up?

Cheers

Hi Chris,
Faint galaxies are just too hard from the suburbs.
Maybe binning 2x2 with a mono CCD would help
to bring out the fainter stuff?

cheers

Hi Allan,

Yes, I think the ultimate plan is to go mono with some Narrowband filters to try and eliminate the awful stuff, may be a while off though, think tax refund time maybe?

Nice image Chris, some good detail in the spiral arms :thumbsup: The only thing I would suggest would be to tweak the colour balance as the fainter regions between the arms have a greenish cast on my monitor.

That's certainly what I did. I reckon Bintel must do a roaring trade in July and August ;-)
