Has Any One used Vegas for Astro-Photography Processing?

Although not new to Astronomy I recently bought the Seestar S50 smart telescope (£529 delivered in UK) to get back into Astronomy. It comes with a high quality small tripod, image shown here is with my existing manfrotto tripod.

Here is an image straight out of the telescope (controlled by an app) exposure 30min.

Here is a processed image of the same stacked photo:

The process is approx as below:
1). Stack raw images (6 frames are taken per min, so 180 frames. Some go through them one by one to manually remove bad frames).
2). Crop the image to remove any stacking artifacts (normally around the edges due to rotation).
3). Do a background extraction to remove uneven light and dark areas across the frame (makes a massive improvement, but complex).
4). Do a Colour calibration to set dark and light areas.
5). Do a photometric calibration which uses existing high resolution photos of the specific object online to balance the colour image.
6). As the image is linear next step is to stretch the image by one or all of these methods, Asinh, histogram, hyperbolic histogram.
7). Remove background green noise as there is no green emissions from space.
8). Apply gentle colour saturation over the RGB image.
9). Further crop the image to focus in more on areas of maximum interest (depends on field of view of the image).
10). Save image as an uncompressed Tiff file for further work.
11). Separate the background & stars from the image to produce two files, one with stars and one without.
12). Process both images in something like Photoshop (I use the free GIMP, as photoshop is expensive and rental only).
13). De-noise the image (use free astrophotography de-noise apps).
14). Make any adjustments to the stars in the image (ie reduce size, number or remove individual stars).
15). Combine background and object image back together and save as one file.
16). Export as uncompressed Tif and JPG as required.
17). Sent image to friends.
Some of the processing tools would be available in Vegas.
 

Anyone had a go at this. As a beginner in astrophotography I find it very complex and can be very very expensive, luckily there are many free programs available to help.

It looks great, but does it do 16:9 or just 9:16?

It is a fixed image native size from 250mm focal length at f5, 1080 x 1920 portrait. An update likely to come which will allow mosaic images to cover larger objects such as M31 which currently get cropped.

Thank you for the information. Unfortunately, it looks like being principally aimed at the vertical phone camera crowd - and only HD not even UHD or above in this day and age. It's therefore got a somewhat specialist / enthusiast appeal I think - IMO anyway - especially since there's no 16:9 capability and thus reframing HD 9:16 to 16:9 in a 4K project, the resultant image would surely be less than satisfactory. Sorry.

What of this do you want to do in VEGAS? Make a slideshow or pan across images once they are processed?

andyrpsmith wrote on 1/20/2024, 9:33 AM

To take the stacked image and apply stretching using histogram, levels, saturating, tint type image manipulation and export a tif or jpg processed image.

The Seestar S50 is an entry level piece of kit which can be a great introduction to Astro exploring, it is easy to set and get going - 5mins and the images are pretty amazing for the cost/effort. The post processing is however complicated as most photography to get going. The Dwarf 2 and the Seestar are the only options at less than £/$ 1000 to get into the field with full sky tracking built in. The restrictions in image size and quality are a function of the imaging chip to get the price below $1000.

And why not use an image/photo editor?

andyrpsmith wrote on 1/22/2024, 11:49 AM

Planets are usually processed from a video. The image from the video is then produced by stacking the individual frames. The final image manipulation is usually made in a photo package such as Photoshop (expensive), I am trying GIMP at the moment. It just struck me that following the stacking process (astro applications usually needed to stack) the image is then manipulated via tools which Vegas has, like curves, levels, sharpening, saturation, histogram stretch.

Here is an image from 91 10sec images and processed by the tools mentioned above.

The Photography Plan for Photoshop (including Lightroom) is $9.99 / month. A bargain IMHO.

I use lightroom, but I only do timelapses with astrophotography, not stills. I use the LRTimelapse plugin to assist with this, then I feed the resulting prores video into VEGAS for further processing.

GIMP seems to be the go to free option for Photoshop in the Astrophotography world.
