Picked a poor day for it with atrocious seeing and 32°C to swelter in , but I got a few images amongst all the faffing about , a few wrinkles to iron out but it's showing great potential.

Even a hint of granulation amongst the noise in the closer view ?

Excellent start with the 150mm, definitely more than a hint of granulation.  What did you use for the close up steve?

I just popped a 2x Barlow in the mix that luckily covered the more interesting bits ... 😏

Not easy imaging in that temperature, did well to get anything to be honest.

Is it just me or are all the "close-ups" striated diagonally?
Particularly noticeable when scrolling.

I can see that now you mention it.

I'm guessing that it's due to the drift I'm getting at the moment (like walking noise in deep sky images) as I haven't polar-aligned since moving back to my old home , and that's the direction of drift at the moment with my "pick it up , carry it out and plonk it down" set-up ... 😆

Now I've replaced the focuser and attached the focus motor to the shiny new one PA is my next task , when I get a cloud free night which looks like not until the weekend.

Interestingly it's not that ... the striations appear in most of the frames upon inspection ... ?

It may have something to do with the dreadful seeing that day , very hot and humid with very rapid shimmering I recall , on first look at the full disc shots a lot of them showed half of the long region relatively sharp and the other side near invisible and vice versa .
