I see large faint but dark circles or patches around stars in the image, what has caused this?
I am glad your experience with your ASA has been favourable.

Hello Mike,
Thank you for your message.
It is the first time i'm posting this image on the forums

. The other image was NGC-3718 and you wrote a comment late in May.
About the dark circles, i displayed the full resolution TIFF 16 bytes image under PhotoShop CS2 with the zoom at 400x but i did not find dark circles. Maybe the JPEG on the web. The TIFF image has not this problem.
I love this telescope and i know you've had a bad experience with yours.
It gives me a great luminosity in my images and i never saw that before.
Thanks once again.
Warmest Regards,
Florent
