My final Jupiter from the last week, taken on the 13th in reasonable seeing.

Jupiter is getting past its best now so any chance to image it over the next few weeks will be a bonus.

On my 8" the ZWO is attached to the Celestron focus knob, which isn't ideal as it allows a degree of mirror flop. My 11" has an old moonlight on the back with the ZWO fixed to the fine-focus wheel, which helps.
A moonlight on the 8" would be ideal so I could lock the mirror in place

Those are my thoughts exactly!

I always use a ZWO electric focusser.

Yes, for this one I was using a 600x600 ROI with a 330 pixel cutout, which gave me 185 fps.
Focusing is what I struggle most with during capture

Another Jupiter shot, this time from the 8th.
Seeing was good but I feel I'm struggling at present to make the most of the conditions.

Maybe I need to go back to the C11?

More fake AI.
Such a shame some people feel the need to spread rubbish like this.

With a change in the weather, possibly my last image of the Sun for a while.
This is the area around active regions 4008 and 4009 and shows some nice bright faculae near to the limb.

Zooming in a bit on the south-west limb.
Not much prominence action at the moment, but a few nice active regions are on show.

The Sun in hydrogen alpha, taken early morning on the 7th before the atmosphere warmed up, which helped the seeing a bit.

I was hoping to compare 2 cameras yesterday but the good UK weather once again had other ideas.
This was a short test video with my usual ASI174 camera.
Clouds appeared from nowhere before I could connect my other camera.
Maybe tomorrow then!

I've reprocessed my 19 March image of the Sun using an "inverted" process method; first one I've done in this way using Affinity photo, so had to figure out a few settings.
This method isn't to everyone's liking, but I think it can help accentuate the prominences

The seeing wasn't great yesterday but I tried a bit of solar imaging between the clouds.
Here are a few sunspot groups showing pleasing detail and surface granulation.

Still testing different focal ratios for imaging with my Esprit solar rig, although the weather isn't playing ball.
This was a quickly grabbed capture from a few days ago

The sunspots are typically much larger than Texas. The features Phil was referring to are the convection cells that appear as "granulation" all over the surface. The resolution in this image is not quite good enough to see them well, but it is the fine mottling appearance

Closer view of active region AR4401 in mono.
The 'rough' texture of the Sun surface is known as 'granulation' although more magnification is needed to see details

The Sun in white light, taken yesterday morning 28th March.

A mosaic of two mono images through my 4" Esprit refractor and x2 barlow lens, and has been colourised.

Several sunspot groups and pale faculae are clearly visible

Final image from yesterday.
Active region AR4402 near the limb of the Sun.
Bright faculae are visible against the darker edge of the disk; areas where the sun's magnetic field breaks through the surface of the photosphere, or visible surface

The shadow of Jupiter's moon Ganymede transiting the face of the planet on 19th March.
Taken with an Astronomik 642nm IR-pass filter. I'm still getting used to using and processing images taken with this. Not there yet, but good fun learning!
