Helix Nebula - NGC7293

[cventer]

Hello All,

After spending 6 hours tonight (yes the wife is away) trying to process this Helix data gathered on the full moon Monday night I am giving up.... I need to re image this under dark skies and take longer exposures. Anyhow its the first time I have imaged this object and considering conditions and what I started with 6 hours ago and after much digital trickery I am not too unhappy with the results...Details of image aquisition are on this link....

I had to make it smallish to hide the noise from lack of signal...

Best Regards

Holy Cow Chris ! you pulled this out of a Mull Moon ? It looks great .

Well done Chris

You can almost pick out the comet like structures you see in Hubble images.

Nice one Chris.. I assume you are using the C9.25 for this? What do you use to get the diffraction spikes? I have used a couple of pieces of wire across the front in the past, but wondered if there was a better way?
Cheers

Beautiful shot Chris, I can't wait to see the final version when you've got more signal to smooth it out.

great work!!!

that's Tops! Again if that is your reject I look at it anyday

Wow Chris,

As always you leave me speachless.

Wow 6 hours, that's dedication.

That's an awsome image Chris, like all the ones you post.

Thanks all for your nice comments.


Robby,

This was taken with a 4" Takahashi FS102. I made up a set of cross hair type vanes out of aluminum and painted them flat black with felt on the ends. They just slide into the dew shield.

If I wanted the same effect on my 9.25 I would use a set of very thin black shoe laces and blue tak them across the front.

The detail in this structure is hard to bring out with only 4" of glass. I will do this again on my C925 in a couple of weeks when I am at Vic South and hopefully get some of the nodules that are in the inner ring....

Processign from a dark site will be a lot easier. A full moon and wide field with the Tak makes Light pollution gradients a nightmare....from the burbs

Best Regards
Chris

Its what john west rejects....

seriously though Chris that is a keeper!

what a stunning image!

[Rodstar (Rod)]

Well done Chris. You can see quite clearly the steams of materialaround the inner edges, like in the shot in Australian Sky and Telescope Nov edition!

Do try that again without the moon, you already have the Northeast Arc (faint feature on right). I consider that the holy grail of amateur imaging, only deep shots can record that. I think you will get even better results without moonlight

Lovely image Chris, good definition in the ring and the central star is nice and bright.

I cant even see this Neb in Brisbane Chris....I tried last night and took me neally an hour just to find it whilst doing 20 second exposure trying to find a glimpse of the Nebula....even with a few images at 40 seconds the detail was virtualy nill.

Once I found it the clouds come over......lol

Great effort for a suburban shot.

I might work on this tonight...weather pending

Yep, the Helix is pretty dim. Difficult to pick up visually from a suburban sight. Thank God for goto.

Good luck
