Homunculus Nebula

[RichardJ]

Hi,

After imaging Saturn and its moons this evening I thought I would have a go at the Homunculus. I've only tried it once before with a modified webcam. It is a challenging object. I'm sure others can do better.

Thanks for looking.

Fantastic result Richard!!!

It's very hard to image, but you've done well. :thumbsup:

[jjjnettie]

:D well done. It's on my to do list. Thanks for sharing.

Great effort! This object is so difficult to capture.

[gregbradley]

Yes that is very very good. It is super hard to capture.

I captured it myself last imaging and it took 1 second exposures in Ha to catch it.

Hi, RicahrdJ. Congratulation for your capture. As I got one similar, with your permission, I am posting here.

To understand the image, I took an Hubble capture from http://pt.wikipedia.org/wiki/Ficheiro:EtaCarinae.jpg and did a saturation, blur, reduction, B/W convertion and rotation to compare them.

It was a surprise I got it. It was took with GSO 12 " - barlow GSO ED 2" 2x - extensor 35 mm - Cannon 350 D - 2 frames - DSS - 35 seconds - ISO 800 -PhotoShop - NeatImage on mar/2012

Hi Jorge,

Well done. It is a very hard object to image well.

I've done a little bit more work and have uploaded my effort. Again, thanks for looking.

regards,

RichardJ

Very interesting capture Richard and a mighty fine Job :thumbsup:
I seen this hubble image yrs ago and wondered where, what etc as it was named just as: A Stellar BadBoy ? ? So your image really puts it in perspective, Top work ! !

[jjjnettie]

Richard, I had a go at this tonight.
It's really very hard to find the right balance with the capture.
I ended up going for 3 seconds subs @ iso400
Hope you don't mind if I share it here.

Hi jjjnettie,

Well done. I like the colour. Next time I'm going to try to get a shorter exposure as well as a longer exposure and combine the images to try and reduce the size of Eta and show more central nebulosity. The seeing last Saturday night was excellent. I need to wait for the best conditions for this task.

regards,

RichardJ

Excellent results everyone.

I think the best I remember seeing was from Rolf a little while back. I'll try and find it later.

[RichardJ]

Hi,

I've uploaded a further image. I'll go back to the original subframes and see if I can improve the final result.

regards,

RichardJ.

It seems to be Eta star, but it is the ejecta ionized clouds.

I could understand it when I took an Hubble image and processed it to be similar to what we can capture with our telescopes.

Take a look on photo that I shared here, where you can see a processed Hubble image and a similar capture that all us got. Take a look on original photo from Hubble, too.

I think that only with more ampliation you will get the separation of Eta and that cloud. On Hubble image you can see that Eta is less bright (because of the size) than that cloud. It is similar to double stars. Where Eta is the faint star.

it seems that all what we got capture is the Hubble's reddish part of nebula.

Rolf's amazing image is here:

It's even better than I remembered.

Great capture Richard.

Hi,

I reprocessed by original images and was curious how my new final image stacked up against a recent Hubble image. I've uploaded the result. I think not bad for a 10-inch Newtonian.

Thanks for looking.

RichardJ.

[jsmoraes]

Great RichardJ, you done. Excelent comparison. That is it.

What seems to be Eta star on your photo, it is Eta star and the bright center of the clouds.
I can see many details from Hubble image in your photo !

[multiweb]

Very cool Richard. You've got some terrific details. :thumbsup:

[RichardJ]

Thanks to everyone for your kind comments. :)
I'm going to give it a more concerted effort when the conditions are right.

regards,

RichardJ.
