Sadr Region Widefield Ha+RGB
« on: 2015 August 22 18:56:45 »
Hi,
Last weekend we went out to a dark site for the Perseids, I counted 37 smile emoticon
Since it was new moon, I brought my portable AP equipment, a Tak FS60.
This is my render of the Sadr region. A 2 tale mosaic.

Image details:

-- Telescope Takahashi FS60 with reducer. FL = 255mm
-- Camera SBIG STF-8300M
-- Takahashi Epsilon 160 for Crescent Nebula Image details (taken 3 years ago)
-- Filters Astrondon RGB + 5nm Ha
-- 2 panel mosaic
-- 9 x 5m per filter RGB
-- 8 x 30m Ha per panel (taken from the city)
-- Mount Atlas
-- Image acquired with Sequence Generator Pro
-- Image processing Pixinsight

I hope you like it!

Clear Skies,

Jose

I really like that image, Jose.  :)

When I clicked on the link to the image, it immediately struck me that "this is what I like". If someone asked me what I like in a wide-field astro-image, this is a good example. I like the colors in the RGB stars, and they're nice and sharp and small. (If only I had a scope that could make such small stars!  :o)  I like the color of the nebulosity, in both the Butterfly and the Crescent. The tonal range in your image also suits my taste very well, too. The regions of dark nebulosity are quite dark, as my aesthetic sense says they "should" be, but you haven't pushed the rest of the background to a very dark level. The amount of contrast in this image suits my taste quite well!

I was tempted to write a reply that said "That's it! That's how all images of nebulosity in the Milky Way *should* look!" Then I thought about it a little more and realized "Hmmm, it may be that not everyone has the same aesthetic sense about astro-images that I do. Instead, maybe I should thank Jose for making an image that suits my taste so well!"

Someday, if I can improve my autoguiding near the zenith, maybe I will be able to shoot a decent Sadr image! Thanks for the inspiration  :)

Really, are clear skies, low wind and no moon that much to ask for?

Marek,

Thanks for you kind comment, I really appreciate it!

The FS60 is very light and easy to mount on top of that the resolution per pixel is quite low, so it is very easy to get nice round stars, even with low end mounts. But I am telling you this after years of imaging with longer/heavier OTAs.

Again, thanks for your comment.

Cheers,

Jose
