Deep Rosette (Hybrid 8300 on 8" F/2.8)


Recommended Posts


Here's the final, processed image - a Hybrid combination of 2 hours of Ha (for luminance) from the new (first light) SBIG ST8300M, with 2 hours of TGB from my good old SBIG ST8300C - through the F2.8 Powernewt - all riding an EQ6 on a high deserted hill out in the Negev desert. Altogether, this is a total of 48 five min. exposures (4 hours).

I have added the link to higher resolution images, which I am quite sure you'd like to see:

- 1200 pixels wide: http://www.pbase.com/boren/image/133327205

- full frame, 2686 pixels wide: http://www.pbase.com/boren/image/133335671

I am also adding an image we've taken of our two scopes at work, under a desert starlit sky: http://www.pbase.com/boren/image/133195339/large

I do hope you like them, and any comments are, as always, very welcome!


Harel :D

Thanks all!

I am happy the 3D feeling came through to you too :-)

About the F2.8 kit - It's soon to go a major upgrade,as next week I will be doing the first light session with the Carbon-Fiber PowerNewt (all other carbon-fiber sessions were done with a prototype, which had to undergo many, many, many runs back and forth to manufacturing...).

I hope to be sharing images from that kit soon.

The image is truly world class. The extreme contrasts in the nebula do indeed give it an outstanding three dimensionality and the tiny cluster stars give a better impression of the scale of the nebula. Lovely stuff. I'm glad the Ha/OSC worked well. I've done quite a bit of this as well. It's a good way to work apart from the cost of two cameras!

Olly, Rich, Wener, guys,

Thanks for these nice words - I am really happy you liked it.

Olly, I am still unsure whether I'll keep us with this configuration. The need to switch cameras (and the re-focus, etc.) is a pain in the neck in its own right. However, the result was so good this time, that I think I'll need a few more trials to make up my mind...
