Brilliant! When you say single video what do you mean?  I am familiar with creating AVIs and using the 10 or 20 or 25 percent ( or what ever  number) best framesto process in registax.  I have always considered each AVI and single video--are your referring to some other process? 

Rodd

Hi Rodd.

Sorry. I'm late to answer you.

You are right. I captured only one AVI and It was stacked with AS3. 👍😉

Thank you @Pete Presland! 😀

The strech was done and It was usefull to me helping the Winjupos measurement using the moons. This final image is North up, both IR and IR-RGB.

Hi @Kokatha man!

Thank you for sharing your point of view! It sure is valuable to me. I really agree with you that it's no simple task to detect any detail on the farther gaseous planets. I didnt think that was likely to happen. But just because it's hardware doesn't mean it's impossible, doesn't It? 😀

What most intrigued me was the comparison i made with images from other aps and the details are still similar. Would different scopes, cameras and sampling result a noise in images producing similar details? I'm thinking about this 🤔

Of course the layers were well stretched post processing to highlight the stains. They reached brighter, but it is a signal that belongs to the original image.

Uranus and Neptune are not so famous targets  between amateurs (as Jupiter and Saturn) and there is certainly much to be discovered yet. What is the real capacity of our setup today? 

Until recently we did not believe it would be possible to capture the Uranus ring, but now we know it's possible.

I will try to make some GIF to certificate the rotation of the details along with the planet (just like Niall has already made). It will not be an easy task, but we can try. If the they keep freeze or unatural movement, it's only noise.

Let's wait for some Hubble image during the opposition. This can solve some of our questions.

Anyway, i liked your points. Thank you!

Best regards!

Hi all,

This is my third Uranus capture this season. I am much happier with this result.

The seeing helped a lot and the sky quality was favorable.

This image is the result of 5 de-rotated videos on Winjupos, all captured with IR742 filter. The result was used as luminance in the composition. RGB came from a normal color capture.

Following the images of other friends, we can notice the atmospheric activity on the planet. It seems to be changing every week. Many changes can still happen until the opposition.

Thats a nice image!

Congrats!

Superb!

Wow! Very Nice image!!

👏

Congrats Steve! Very good begining!!

James is right about the difficult to set a good exposure for a moon mosaic. It's a huge target with so many different brightness areas.

The way to avoid over exposure is set gain and exposure time in the brightest surface point. 

But you really got a great image

Heya,

So I'm attempting my first ever mosaic. Just thinking of ways to make my life easier. Should I stack the images separately and then do the process of merging manually in Photoshop or should I stack them all together in DSS in mosaic mode and would that even work?

Thanks in advance

Clear skies!

Hi Simon.

I dont know the target you captured, so I will use the moon as an example. Ideally, you stack the images before making the mosaic. A good reason is that AutoStakkert alignment points will use the algorithm to determine frames quality and position to produce a good final image. If you try to build the mosaic first, these alignment points will not work well and even the quality graphic can produce a false result.

Stack each video first, then build the mosaic. Finally make adjustments to brightness, contrast, sharpness ... using your favorite software. A good one for mosaics is the Microsoft ICE. It's free and very easy to use. Worth it.

A good start there Lucas, Uranus is at the top of my list in coming months as well.

This was my capture from 2016/17, it contains some good advice capturing and processing Uranus.  Lots and lots of frames for me is going to be the key.

Don't be afraid to push the gain to max, the image on my Firecapture screen was so noisy it did not resemble a planet at all.

 

 

Thank you very much, Pete!!

Great tips and certainly i'm going to try next time! Maybe today, i hope!!

Your Uranus is amazing! Congrats!! An inspiration for me!

Sweet image, and indeed, the terminator is always worth exploring. Even some fetures are worth imaging when the sun is high above the lunar horizon. Albedo features like ray systems and micro impacts in mare are interesting when the sun is high.

Nice words! To be honesty, i never captured moon during the sunlight.

I think i'll gonna try!

Thank you!

I never usually consider getting out imaging even the moon is nearly full but your image show it I'd most definitely worth it!

Thanks Craig.

Terminator is where we usually find some interesting crater shadows, even in a nearly full moon.

It worths while! 😉

The IR filter always help to go deep.
In this image i liked how evident all the relief is.
The shadows are projected over the back regions.

The moon was 91.5% illuminated.

This M16 is awesome! 👏👏👏👏

The image is beautiful! I liked the colors.

These are M20 and M8. Trifid and Lagoon nebulas.

Maybe you could try a star reduction in the Pixinsight. This usually brings more contrast to nebulosity.

Congrats

Very Nice!

Congrats!!

Thank you Rodd

I didnt have too many results like that in 2019, but sometimes things go very well.

We have a powerfull scope. Hope you have your moment too.

One method for the uranus and Neptune is just to capture a ton of IR only and false colourise it. There is very little detail in RGB for these targets.

Exactly Craig.

The RGB channels are only for the colour correction. The IR bandpass filter gives deeper details.

Nice capture, really nice shot.

Thank you friend! 

ISS - International Space Station

No time to fix focus, parameters or anything else ... So is the ISS capturing. Preparation is prior and should be a well-given shot.

In this attempt not everything went perfect, but each opportunity has brought evolution.

I would like to capture Uranus like yours but it still alludes me 

 

keep on going and i look forward to seeing some more images of a not so popular imaging subject

Thanks Moody

I think a Uranus capture needs only the same three things we want for another solar system targets: 

1. Good seeing

2. Good telescope aperture

3. Good filters

Generally, the first one has been my enemy 😂😂

From a list of videos, this image was the final best among all.
Maybe a cloud pattern can be noticed at pole.

Now i'm waiting for a good sky to try capture in mono (IR)RGB.

Wonderful image!

Congrats!!

Unfortunatelly one of my last Saturn images from 2018 was taken almost a month earlier than your.
