SPX350 F19.5+F30.6, Mintron12V6 (GStar-Ex), Astrodon filters.
Impressed with SkyVikings image of this supermassive star which erupted in 1843 and should have gone supernova but instead remained variable with a double cloud which we now see. Mass of this star is 100-150 solar masses and one of the largest mass stars in the galaxy known.
Used a TVx3 Barlow and then a 5xPowermate above roof and the 5xPowermate had issues with heat over roof but red turned out well with Ha. The TVx3 had no such isssues taken a night earlier.
F19.5 was 2000 x 0.24sec exposure for R and 1000 each for G B Ha.
F30.6 was 1000 x 0.32sec exposure for R G B and 350 x 2.56sec for Ha.
Stacked with Registax and processed in CS3.
Thanks, John.

A major result there John ! Kicking more goals.
Well done

Nice work John
The long focal length helps with this object huh? bit like planetary imaging really and very seeing dependant.
There is a lot more ejecta and detail to be captured out in the darkness around the Homunculus but this an excellent mimick of the Hubble version, looks great :thumbsup:

Hello John,
That is one impressive result. I don't recognise the scope you used. What is its aperture? and is it a refractor or reflector or SCT?
Regards,
Tony Barry

Such great work John with impressive details - and glad to hear my image can inspire others to try some extreme high res too.
It looks like you captured some of the fainter ejecta around the nebula as well, awesome. I've been wanting to redo my version of it and hopefully include these fainter areas as well. Your image is definitely inspiring so maybe I'll have another go soon :)
Thanks for sharing.

Wow thanks for the big response, took this in Jan but been busy with Saturn/Lunar processing. Pity my roof is just below and can't see the Tarantula was going to go for Supernova 1987A but too low unfortunately.
Short subs mean overcoming the seeing to a degree as the Mintron is so sensitive. F19.5 gives best Ha outer area. Don't know why others ignore it as it is very bright and obvious at 2-3 meter FL. Oh yes the Eta Carina nebula is why it is ignored, a glorious object to image!!!
I emigrated from UK to Brisbane last year and brought my Orion Optics Newtonian with 350mm primary (14") at F4.53. I image deep space and planetary with it and very glad I bought it over with the shipping.
Thanks again, John.

Ditto what Ron says!!!!
Wow John, fantastic result.
I have tried to get the Homunculus soooo many times over the years, but gave up.
I have seen it visually but I never seemed to be able to image it.
Top stuff :thumbsup:
Wow - congrats on a STUNNING image! Thanks for showing.

Talk about Xtreme imaging cranking the power right up.
This is excellent John.
Congrats!!

Hi John, I've popped your glorious image on the IceInSpace facebook page (http://www.facebook.com/photo.php?fbid=10151545008441203&set=a.443095681202.235512.114571796 202&type=1&theater) earlier on today. :D
It remains todate the best pic I've seen from an amateur using a ground based telescope, a favourite pic of mine!
Aha! I was wondering how this thread got revived :lol:
It really is an amazing image.

It's a bloody ripper!!!
Was thinking how it the h-e-l-l could anyone from Brisbane image this for the last 6 months, and now I see how ;)

I thought I'd come see what all the fuss is a bout ...
'bout bloody time someone got this, this good! :lol: brilliant shot :thumbsup:
Now take the same every week and in 5 years I want to see what difference you can discern over a 250 frame time lapse ;)

Brilliant shots.
Greg.
Fabulous idea. How many of the 1000 frames did you keep to create the image? I've seen some of the detail visually with a 24" Dob in Coonabarabran.

Thanks for the reminder of my deep space imaging, seems like imaging in Jan and Feb in Brisbane is impossible of recent.
These exposures were from a quarter of a second to one third of a sec as it is so bright so I stacked almost all using Registax only removing the recentered images that showed movement. The detail was shown in the red channel which as usual was quite sharp.
The Mintron (GStar-Ex) is very sensitive and will work at these unusual focal lengths but finding objects at 7 meters FL plus is bloody tricky using star hopping which is a slow process and poor seeing can easily turn stars to blobs, so I had a good night back in 2011.
I never got a look at it through the eyepiece unfortunately.
Regards, John.
Again, amazing.
Well done.

It's a great result - don't think I've seen better except of course from Hubble.
