That looks GOOD Andy. I too need to work on my processing skills! Not had enough cloudless/rainless opportunities to capture many sun piccies. Have you tried using Astrosurface - most of what you need in one package....

Nicely done.

I'm still in two minds about it. Recent solar images haven't turned out as well as the usual ways. Wouldn't mind seeing a button to quickly colour Solar images....😁

Absolutely stunning. Sadly cloud obscures our view.

And you've got the bridge across the spot. Solarchat had an animation of activity across it.

I chose a ZWO EAF. Less pricey than the Pegasus. Runs on 5V, so USB to PC or Cool Cam - one less power hub to worry on. Does the trick and tests out OK through Sharpcap.

Know what you mean. I've had just 2 days with enough sun since start of April. I'm getting rusty, too, on process! . I'd blame something, but too many things to consider which something!

I have a simple solution, just tested manually. An 1/2 inch extension tube with sct m/f thread. Quick test on solar just now. Not perfect focus, as slewing was manual at the time, but enough to show a motorised focuser will work, connected to the OVL Crayford. ( It works on my Skymax.) At 1/2 inch there's a prevention on extending the mirror screw fully outwards, but as the Mak focuses about half way in it shouldn't affect operation. Now to source a focuser. Probably pegasus.

Absolutely gorgeous detail...

OK - gotten them through your Flickr link..... Wow.

Hi, I can't open any of these, I'm getting Flickr: "Page not found" errors

Only a little!

That's some capture! Well done.

Yes.

Great image plus the detailed description. Thanks.

As seen from NE Scotland last night - timelapse from two cams, vertical and horizontal. Both use ASI 178MC cams running under AllSkEye software. On the overhead, North is top and East is left... Site's a Bortle 4 - Aberdeen lights at the bottom. Youtube link

Hi Alex, Why? Because I remote view from indoors. This would require some motorised focus unit attached. My OVL focuser is of the correct fitting, but the position of the micrometer screw prevents it being put in place. Your suggestion of replacing the said screw with an alternative is, certainly, possible. Geoff

Weeps! Brilliant .... Where's the envy sticker! 🤠

Thank you Nicolàs....I think! I'll be honest, it's getting a bit too complicated!

And how very well you used that short window. Marvellous...

I need to move south! Sun's, barely over the yardarm these days!

Thank you for the clarification. I'll put it down to seeing conditions, which means I ought to pay more attention to the atmospheric conditions - that I do.

Taking that to a previous question, then - if the sampling ratio f and pixel size isn't correct, could that effect the ability to achieve focus easily. I know conditions weren't good the last twice I tried Jupiter/Mars but I just couldn't get focus - not even a hint in lucky imaging - and the 174 was motoring at ~100 fps.

What happens analysis-wise if one of those images (or a live image) is de-focused?

I just did a search in the plugin library. It was the first on offer.
