PN K2-15, ngc2579, Tarantula, Eta carina nebs

[tornado33]

Hi, hand a huge imaging fest last night as it was clear and very transparent, and I had Houghys cooled 350D DSLR here, so I did almost an all nighter
Planetary Neb K2-15 in Vela. 2x10 mins ISO400
NGC2579 in Puppis 2x10 mins ISO400, and a full res. crop
Tarantula nebula. 5x10 mins ISO400
Eta Carina nabula 3x10 mins ISO400

All shots using Houghys Astronomik CLS filter as well. Baader MPCC coma corrector also. Sensor temp around 7 degrees C. Ambient temp over 20 for much of the night. 10 inch f5.6 Newtonian, hand off axis guided.

All in all one of the best nights in many months by far in Newcastle.

wow, that tarantula one looks amazing, shame about the plane/satellite,

[tornado33]

Thanks. Yes it was like Sydney Airport, never seen so much air traffic about last night. I already ahd to reach for the scope cover when a much bigger plane, or one with very bright landing lights on came over (why do they lave their landing lights on when cruising?) I didnt see that fainter one come over.

All excellent images there Scott.

Scott,

Very well guided, excellent focus. The Tarantula has too much yellow/red IMHO. Try balancing in PS with a Tad more Cyan

I took the liberty here http://www.atscope.com.au/BRO/reproc...ott2070_RP.jpg

Cheers

Thanks all
Thanks for the input Peter. Here is the Tarantula with a little Cyan added. Nebula filters are great in making emissionline nebulae stand out from the sky background, but they do add a colour cast to the sky background, trying to balance that to grey can often make the nebulae colour a bit off.

Very nice images Scott, despite the planes. The mind boggles when I think of what you would achieve at a dark site.

Plenty of detail and colour.
Not sure that the tarantula should be so red 'though?

[tornado33]

Thanks Jeff. Indeed, from a dark site like your place I doubt a nebula filter of any kind would be necessary, just maybe a very light one to filter out airglow only, as thats the only limiting factor you'd get . Id easily be able to go as long without a filter as I would with one in Newcastle.

Lovely work Scott. I had plans for an all nighter, but sometimes things just don't go to plan.

It sure was a nice night.

Yep that looks good, thanks
Scott
PS theres cloud approaching from the SW now, I only hope it clears.

Awesome images!

I particularly liked Eta Carina

[Ric]

A very nice selection Scott, lovely imaging.

Cheers

you had a busy night Mr alder - dont wear my camera out will you...LOL

[netwolf]

Scott, lovely images all. The Tarantualla is stunning, this is going to be my 2nd object to concentrate on, its at the right place when i am done with Orion for the night. As said in another thread i think i need to invest in some filters. I have not looked into filters at all aside from planetary work. Is your camera modified?

Regards

[Garyh]

Very nice work Scott! I like that Tarantula one!

[venus (Lydia)]

Amazing images there Scott, well worth a night's lost sleep. And yes a very clear night last night I also had a look.

[glenc (Glen)]

Thanks Scott. I was interested in the image of N2579, is it a PN?
There seems to be some debate about it.

[citivolus (Ric)]

Quick note: I was doing some digging as K2-15 was on my observing list, and according to http://www.aanda.org/index.php?optio...100.right.html , K2-15 is now considered to be a reflection nebula as it has an embedded infrared star cluster.

Here is their data, from ftp://cdsarc.u-strasbg.fr/pub/A%26A/400/533/table3.dat :

23 263.25 0.51 8 48 48 -42 54 27 1.5 1.3 in Munch23=K2-15 IRC not PN

Likewise, NGC 2579:

busyy night scott. great images lov the ETA. more unknown objects for me also to target. thanks.

[tornado33]

Thanks all
Yes it seems some may not be planetaries after all, ive come across other objects like that. Some are even listed as emission nebulae and planetaries

Yes it was my busiest night for a while, sadly weather has never allowed an all nighter since.
