Ah okay, no worries. At the end of the day, so long as you're having fun thats what matters!
Good luck with your future plans and aspirations. Its a slippery slope 😂

Typo - ignore the first question mark. I wasn't asking a question!

Good to hear? Did you calculate f-ratio by image measurement?
Ive found quoted barlow powers and calculations done within apps are very unreliable

Nice Martin 👍

Experimenting with image scale. Right is with x2 barlow, is very oversampled at f/27, and lacks contrast and detail. Left is no-barlow, is slightly undersampled at f/11, but although smaller shows more detail.
Theory suggests f/15-20 is the sweet-spot.
Interesting and fun, but more work needed!

Pythagoras and the north-east terminator, a few hours before full moon a few days ago🔭

Jupiter on the 2nd March.
Ive been struggling with poor seeing lately, I think due to heat from my house.
From image scale measurement I now realise my current set-up is oversampling, which is not ideal.
I down-scaled this image before processing. More testing needed on this.

No worries mate

Generally just an IR cut filter.
I usually try and expose so the highlights are not blown out, and then lift the darker tones with levels or curves. Use of maaks or gradient masks can sometimes help protect the highs

Excellent 👌

A closer view of the Alpine Valley, Vallis Alpes, one of the best examples of a tectonic fault on the Moon. About 100 miles in length and 6 miles wide, a narrow rille runs down the middle, which is very faintly visible in this image if you squint a bit!

One of my favourite areas on the Moon, the northern shore of the Sea of Showers.
Lots of interesting features can be seen here, including the majestic crater Plato and the Alpine Valley, like a chisel cut through the lunar Alps mountain range

Yes, as Peter said.
I caught it just by chance 😂

Another shot from the 25th.
The "Eyes of Clavius". An interesting illusion created by the morning sunlight catching the rims of craters inside the wonderful crater Clavius in the Moon's southern highlands

Thanks

😂

Yes you could be right there.
Shame the mission hardware is too small to be seen!

Youre welcome mate

Lovely image Martin

Thanks

The Straight Wall. Actually a gentle slope, but the low angled Sun really makes it look dramatic!
A lovely area with lots of interesting features, including the narrow rille Rima Birt, about 50 km long 🔭

Wider angle view of the lunar Apennines and Hadley Rille.
Taken last night in average seeing 🔭

Cheers Martin

Thanks Chris 🙏

Forgot to say....
Io can be seen in transit to the left of centre

First image of Jupiter, with Io and it's shadow, and the GRS, taken with my new Uranus-M mono camera last night.
The plan is to get an IR pass filter which will hopefully help me get sharper mono images to use as a luminance layer combined with colour from my Uranus-C camera.
Good to have a plan 🤞🏻

First Jupiter session for a few weeks due to horrendous cloud so far this year.

Youre welcome
