Something quite different

Wha? TWO COMPLETELY CLEAR AND STILL NIGHTS in a row in Newcastle? .....Woohooooooooo

Not sure about most of you guys but I haven't seen an image of this bit of the Vela SNR before that wasn't a part of a much wider field view..? Heck, I don't even know the catelogue number of anything in the frame

It proved to be quite a challenge to record but I picked it not only because it is seldom imaged but because it is a lovely mix of stuff - emission nebula, refection nebula, double helix shaped flouresent shock wave, dark nebulae and some sparkling stars too.

I did do 120min of Halpha but the region proved pretty faint in Ha thus I found even this amount of data didn't really enhance the image and did little for a final LHaRGB in fact it only added noise really (longer Ha subs - I did only 10min subs - would have been better probably?) so I decided to drop it from the colour combo altogether leaving the final colour image as an LRGB mix. This was dissapointing, not to mention a waste of a few hours worth of stuffing around for a guy who is portable doh! grrrrr... but the good thing about imaging an area of faint stuff is that very little ddp is necessary to bring out the dynamic:

Smaller frame (1.6meg) to fit on your screen better

Larger frame for surfing:

Here are some close-up crops to simulate longer FL on the more interesting sections:

and here is the Lum + Halpha only version (I love the sentimentality of B&W )

enjoy

Mike
ps. I have a set of just released ultra low reflection Astronomiks Ha OIII SII filters coming next week...so look out! Mike will be doing green and yellow goopy images too then a new set of ulta low reflection LRGB filters will follow soon after too, so hopefully those pesky little halos around stars will be a thing of the past....?

Mike,

Lovely stuff - it really is a beautiful target - like you said it has a bit of everything.

Something to add to my list one day thats for sure.

. . . . need a password for the L+Ha though !

Cheers

Love the twisting tendrils Mike. What an amazing sight. Luvverly!

What's with the holos around the brighter stars? I'm not criticizing (how could I?) but am keen to know why they exist. Is this just a function of you having to pull a rabbit out of the hat as far as available dynamic range goes?

Looks very nice to me Mike. Below is an alignment star map of nine panels taken with my 300mm lens. This is for the mosaic I am doing. The size is 17x11.5 degrees. Your image and the HA&O3 enhanced image centered on the Vela Pulsar are also added with RegiStar.

Do you know where you are yet? Just joking!

Hey thanks Oma-sharif-oo

Glad ya liked it.

Th halos are coming form the Astronomik filers (at least I am pretty sure..?). I have a set of brand new to the market low reflection Astronomiks Ha OIII SII filters on the way next week and a set of same in LRGB to follow some time after (once they are released) so I hope this will remove this issue?

Mike

Actually I was hoping you'd do that Bert, I was going to ask but felt pretty sure you'd do it anyway It really is an amzing region of the sky that and it can keep us busy for a lifetime (unless you are Rob Gendler of course...he has imaged it all in high definition colour )..try hard

Mike
Love you RG, just a term of enderment

This image will give you an idea of the quality of the mosaic. So far in tif form it is 350MB+.

About 1MB

Ah Haaa - a man who appreciates subtle beauty! A very cool image Mike!

10min subs for Ha? Dreaming of owning a large aperture reflector of some kind perhaps- hmmm?

Cheers, Marcus

I love the simulated long F/L shots haha.. Nah a very fine shot mate! I am rather impressed that recently theres been a few images of really obscure targets on the forums... This is another fine example... And Although I love these obscure targets, I woke up at 3am today for work, looked up at the sky, saw scorpius and thought "Oh yeah... its Rho time!! ." Planning to shoot yet another incredibly overshot areas after attacking M42, 3372 and 2070


Well done mate.
Alex.

Like the HII nebula Mike ... nice colour and detail in the dark lanes.

now if you can just add another 30 or so panels to finish it off

what made you target this little bit specifically , or was it just a lucky dip?

Again we see why you are highly respected in this field Mike.
A very good pick of the object as well, like you said, not much of these being tried.

Theo.

Subtle beauty alright the whole Vela SNR/Gum Nebula region is just incredible. It's a nother example of something we have down here that just blows away what they have in Northern Hemisphere ala the Veil Nebula

Large say 12" say F3.8'ish maybe?

Yes very cathatic....I'm pretty happy to have found somewhere to image from within 45min of my home and under pretty dark skies... still a pain in the proverbial mind you to lug everything there, just a shorter trip

Like I said the image scale is just enough and the FOV allows capture of plenty of offerings in one frame The Vela region is full of lots of stuff just gotta search it out..like the Great Barrier Reef, you've got'a know where the best spots are though

Yes it makes a nice contrast with the delicate filamentarty structure oposite, that's why I went for the framing. Looks liek a bit of dust extinction too as the neb is very red/orange.

30 frames???? man I'm happy with just one in two nights.... I have a nice site now but sheesh the whole rigamarol to get out and back with all the kit is still daunting, man I need an observatory again....

Sweet shot there Mike. Love the balance of the shot with the SN tendrils and the nebula on the left. Very nicely done.

Very nice Mike. I love the little Nebula . Could almost be a baby Trifid Nebula.

Where do you get such obscure targets?
