Cloud moving around, can't really make any decent image, just a record.

1048 and 1050 (GMT+1), Ranger at prime focus, Solarmax 60 with BF10, ASI 290mm

20230525 H-alpha, Coronado BF10 fixed!

1229 (GMT+1), exposure pushed up to show prominences better, taken with 2x barlows:- 

1226 (GMT+1), AR3310 taken with 2x Barlows:-

1223 (GMT+1), taken with reducer, slightly drifting to allow full disc after stacking:-

I'm glad to announce that my BF10 was repaired successfully!

In business again!

Repairing my BF10

Sent an email to Meade and their response has been quick!  As expected, I will need to send my BF10 to the USA back and forth to get it fixed by them, the cost is not too high but worldwide shipping twice would be both expensive and risky.

Scanning around the web, and found some other possible solutions.  Better yet, they might offer better solution than Meade, which will get rust over time again.

Send an email to https://beloptik.de/, got a slow but positive response.  The cost is slightly lower, and I don't have to send my BF10 there.  That possibly account for the price difference, since I'll have to replace that ITF myself.  But it seems not too hard.

Good me luck, I really want to resume H-alpha imaging.

20230516 Sun, probably my last shot

 

Actually, |I don't have to process this image but since it might well be my very last shot, why not just keep it as a record?

The view is very great with my eyes, just very bad with the camera, guess what.

The exposure had to be very long, I believe my blocking filter has heavy rust.

Naked eye view tends to be a bit too bright for H-alpha, but then it's prettty dim now.  Therefore, it's still good enough for the eye, but it's already too dim for a cmaera.

I have sent email to Meade to see if they can help, but the chance probably slim.\

I would keep the filter for visual observation, and it still works out great.

I might sell the azgti mount, for it's more liike for imaging the sun., maybe selling that ASI too.

|For some unknown reason, the image turns out to look white light.  I still remember when I removed the camera, I could see a long filament on the solar disc easily.  Wondering if my camera was setup incorrectly.
