quick red spider

[Shiraz (Ray)]

Hi

Clouds have been overwhelming lately, but I had about an hour of good Ha and another hour of so-so Ha data of this object from a month ago. Put it with a little bit of colour taken recently (in desparation) while the moon was up.

The image is scaled by 150% since this thing is very small, but it is a quite spectacular bipolar PN with quite large faint extensions beyond the four bright lobe edges and a very bright core with a small darker central region - and yes, it is red! Thanks for looking. Regards ray

A very interesting object. A bit like the Butterfly Nebula.

Was expecting the tarantula. Never seen that one before. Pretty tiny.

Thanks Greg. these bipolar PNs all seem to have quite similar structure. Although this one is called the red spider, it certainly does look like a butterfly as well. the Hubble shots of this show some very beautiful and graceful detail in the clouds - I could only get a rough glimpse of the detail, but it was still worth doing.

thanks Marc. yep it's small - the main nebula has about the same angular extent as Jupiter.

Tricky and interesting target, Ray. Well done!

Excellent quicky Ray! Love the negative view too, shows some nice faint extensions, very cool little PN that. There are so many out there...I recon if I ever got automated (one day and prefereably with a longer FL scope) I'd like to do a few nights script and hammer some quicky PN's one after the other.

Geez Ray that's challenging!

I presume it's NGC 6537 in Sagittarius ?

If so guide 8 has it at 15 arc seconds, that's small!

Good imaging BTW!

Cheers,

Justin.

That's impressive Ray.

thanks Mike. what sort of pixel scale do you think is needed? - a bit more image scale is definitely worthwhile for these things.

yep, its 6537 - not big and flashy, but I think it is fascinating nonetheless.

Nice work Ray! Certainly more to it as revealed in the negative. Well done!

thanks Rod. regards Ray
