Many details visible across the planet, interesting to note as the two white ovals above the Oval BA are keeping constant.

Very nice...Those ovals are indeed looking good and also well captured, thanks Avani...

Excellent images, Avani. The UT 6.59 image is particularly beautiful. Thanks!

Lovely images! I've admired your planetary images in the past, but have only just noticed that you use a colour camera.

Just wondering if you did or maybe still do mono imaging, and how you find the two methods compare... Mono vs Colour?

Hello Tom!
I've never used a mono camera, so I can not compare.
I assumed that a mono camera for my specific seeing should not surpass one colored, I explain why:
Hardly I get more than a 5 minutes of seeing stable, it alternates very quickly from good to bad in my region. So if I use a mono camera, I will hardly have a good capture on all 4 channels. Already a color camera allows me to make up to about 4/5 movies in the space that I would lose to make a single photo with a mono. In this situation, the possibility of catching a good moment in one of these 4/5 movies with the color, is much higher than getting the 4 good movies with a mono.
In short, if I make about 20 to 30 colored films I have a good chance that at least one of them has an acceptable quality.
If my seeing was more stable, the conversation would be different. Even so in the future I intend to get a camera color just to make those photos at the ends of the spectrum like IR, Methano, UV, etc.

Fabulous captures Avani.

Hi again - sorry for slow response - lots happening!

When I started doing planetary I got a 290MC and then I noticed that one of the top planetary imagers uses a mono, so I switched. To be honest I couldn't see much difference between them, but to be fair my images aren't in the same league! It is certainly a good deal more time consuming to process mono, but then as you say you have the option of CH4 filters etc. I haven't tried that yet.

I also notice you use a Luminance filter - do  you find that helps?

Fabulous images Avani, I too like the 6.59 UT version the best. Keep them coming.

An L filter is essential for a color camera! It blocks the IR and UV that detonate the quality in the regions of blue, green and red.
Using a luminance filter is mandatory!
