Great stuff!! Which scope? Tracker?

I now have a Skywatcher Star Adventurer GTi--have yet to dial it in..much to learn!


Hi rbtree
Thanks for checking out the lunar images and for the comment.
I used a Meade LX 200 16 inch Schmidt Cassegrain telescope with a canon EOS 5D Mark IV in 4K video mode to capture multiple 2 minute videos. The mount used was an Astrophysics 1600GTO mount set for lunar rate tracking. Each video was process with PIPP (Planetary Imaging PreProcessor) to convert the .mov files from the canon to .ser files that could be used by Autostakkert to stack the video frames. I then use Registax6 to do some wavelet processing on each stacked image to sharpen it up. The images where then combined with Microsoft ICE (Image Composite Editor) to make a full image of the moon since the prime focus of the Meade is 4064mm and only a part of the moon could be imaged in each video. Pixinsight was used to increase the saturation on the second image. Note: The only software that isn't freeware is Pixinsight.

If you are interested my Website has other astro images I have taken and an information section on each image (the i icon). Most of the images contain information on how the image was taken (filters, camera, lens, number of images stacked and processing done).

I much prefer the 1st image; much more natural. However, the color enhanced version is nicely artistic...

Hi bwana
Thanks for viewing the images of the Waxing Gibbous Moon and for the comment. The color image although not natural does give a better idea of the mineral distribution on the moon. The orange areas show higher concentrations of iron oxide (FeO) and bluer areas show higher concentrations of Titanium oxide (TiO2). The whiter areas are locations of more recent impacts.

At first I was about to say, you have very steady skies, until I read your post. People that take single exposures of the Moon don't realize how much the atmosphere plays a part.
Nice job and the details came out beautifully.


Hi alberio
Thanks for checking out the image and for the comment. Yep, the longer the focal length the more the atmospheric turbulence blurs the detail, however stacking many images greatly reduces the effect of that turbulence.

The images below were taken on the evening of 4/19/2024 at a 4064mm focal length using a full frame DSLR in 4K video mode. Since the full image wouldn't fit into a single frame multiple videos were taken each around 2 minutes long. For each video ~ 50% (~1800) of the best frames were stacked to improve the image to reduce the atmospheric turbulence. The stacked images were then combined into a single image of the entire moon. The first image is the moon as it appears to the eye. The second image has the color greatly enhanced to bring out the subtle colors on the lunar surface. Both images required some compression to fix under the 20meg limit.
All questions comments and suggestions are welcome.

I redid the LRGB combination as HaHa0.9xOiiiOiii. I think using Ha as Luminance did improve the image but still fighting thin cloud to a degree.

Thanks for the suggestion.

Nice detail in the image. I like the contrast in the nebula.

White Light grayscale

Shot with a Sony A7R V camera, Sony FE200-600, Sony 1.4x TC and Orion solar filter, tripod mounted.

Best single image from 46 images captured. Pre/postprocessed in PIPP, Lightroom and Photoshop.

Earth has been added for reference. You'll find it below the big sunspot on the right.

Enjoy!

Nice contrast that really brings out the granularity in the solar image. Trees can be a pain alright.

I've been considering a smart telescope package such as the new Celestron Origin.

All of the smart telescopes I've looked at are based on an Alt/Az platform shooting 10-15 sec subs to keep field rotation under control unless they have built-in field derotation.

The Origin is based on Celestron's Evolution mount which I've had for a couple of years, so I mounted my Stellarvue 60 (SV60) and QHY 163M with filterwheel on the mount and proceeded to shoot half an hour of 10 sec. subs of the Orion nebula with each of Lum, Ha and Oiii filters (180 subs per each) just to see what I could capture. It should be noted the SV60 and Origin focal lengths are almost exactly the same at 330mm; however, the focal ratio is considerably different at f/5.5 and f/2.2 respectively. This will significantly impact what can be captured with 10 sec. exposures off the Origin.

I used SharpCap's Live Stack tool to align and stack the subs as they were captured giving me three stacked images to play with. I aligned these stacks in PixInsight and created a LumHaOiiOii (LRGB) color image and tweaked it in Lightroom. I was pleasantly surprised with the results.

The only thing I'd do differently if I did this test again would be to shoot a few, maybe 2-3 minute, sessions to recovery the Trapezium area of Orion.

Enjoy!

Great images of M42. I have played with assigning different filter images to different color with a fair amount of success. In some cases using Ha for the luminance is quite useful. Note M42 also has a fair amount of SII that can bring out some other details in the image.

I'm just remembering the 2017 Great American Eclipse of 2017. I wish I could post a video of the moment when people could remove the eye protection. The first is my version of the Diamond Ring, with Rubies on both sides, then just after the ring where the prominence took front stage, then the Corona.


Great shots of the 2017 eclipse. I hope it will be clear for the upcoming eclipse.

Orion, a place that draws a newcomer as a moth is drawn to flame and light.

I have long followed the complexity and challenge presented by this forum in particular and have at long last realized that technology has been changing and what was once very difficult (likely impossible for me) has become at least approachable. So I decided to learn and expand my frontiers by seeing what I could see.

Recipe:
Thirty exposures at 180 seconds each, 20 @ 90s, 10 @ 15s.
Old Canon 400mm lens plus 1.4 extender
ZWO AM5 mount
ASI2600MC-Duo camera
ASIAir computer to control the mount and camera
pixInsight software to stack and edit and then input into PS for more play
and half a moon under dark Maine skies

Shot the full moon in two sessions. Once at midnight and again at 7:30am.

The midnight pix with a Sony A7R V and Sony FE 200-600 lens. The morning shot with a Sony RX10 IV.

It didn't really look all that 'mini'.

Enjoy!

Nice contrast and detail on the full moon.

A reasonable day for some solar imaging.

Used a QHY462C camera on an Astro-Tech 65EDQ telescope with a Hershel Wedge and Solar Continuum filter, mounted on an iOptron CEM26 EQ mount.

Shot eight video sessions of 1000 frames each and processed for the best five frames in PIPP then manually picked the best of the best for final postprocessing in Lightroom/Photoshop.

I've included the results from six of the eight sessions, one of which is a panorama of two sessions.

As mentioned in a previous post, Active Region 3590 is HUGE. I've included three images of this sunspot simply because it is rather impressive, all of which are slightly different!

The Earth is shown for reference (to show how small we are).

Enjoy!

Nice sharp images and your filter creation works well. Also probably easy to remove at totality. Thousand Oaks has quality products.


Hi alberio
Thanks for checking out the solar images and for the comment. The film seems to work well, will be easy to change out if it gets damaged and is a lot less expensive than the glass filter I have for my refractor. I plan to use both for the eclipse one with my old canon EOS 60D and the other with my canon 5D Mark IV.
