Lots of tiny tarantulas: NGC 300 in H-alpha

[RobF (Rob)]

Fascinating to see all those massive bubbles of H2. Love it!

It really adds to the colour image as well. Love it.

Greg.

Thanks, Greg, our tails are wagging!

Thanks very much Paul. Wasn't clear how that technique would go, but it seems workable.

Thanks Richard. While the very bright Tarantula-like rings are dramatic, it's the very large but subtle ones that seem to add the most interest for us.

Thanks, Rob, and thanks for the virtual beers!

fascinating look at 300. Haven't really bothered much with Ha for galaxies, but this image shows how much there is to see in that band. Thanks for the re-education.

Thanks, Ray. Next year, perhaps, we'd like to get much more H-alpha, to reduce the grit.

I really like the B/W version - very captivating photo, thank you Mike and Trish

[alistairsam]

wow, fascinating. Who'd have thought. well you'll did.
so now do we all set our filters to Ha and point at Galaxies?!!

nice work

Cheers

Thanks Slawomir and Alistair. Does make us wonder how many of the dozen biggest nearest and dearest galaxies look so impressive in H-alpha. Magellanic Clouds and Barnard's Galaxy show a lot of interesting structure in H-alpha.

Best,
M & T

Very nice M&T! The Ha only is certainly a different and informative view of 300! Didn't realise there was so much emission in there! The colour version is just beautiful & quite compelling too!

Cheers, Marcus

Thanks, Marcus, that's very kind.

Wow. Excellent photo. Really liked touring the large version. Thanks.

Thanks Mike,
Yes - you have a point.
I also found this ESO picture of NGC 300 in Ha.

A wonderful journey playing 'spot the Galaxy' in the background whilst appreciating the foreground display.

Thanks, Rodney. We had fun too.

Thank-you's slightly out of order due to pressing the wrong button.

Cheers, Trevor, we're glad you like it.

The Ha dropped into the RGB looks great, its supprising the number of nebs that pop out.

Thanks muchly, Fred.

Would like to go deeper on this. Sadly, our focuser is playing up again. Our fault for having a ton of stuff hanging off it. Just written to PlaneWave asking for a quote on a replacement so we can wear that out too.
