Hello Salvatore,

Thanks for your reply!

When I clicked on the above link that you said to select, I get the nasty message below
"Your connection is not secure"

The owner of cdn.astobin.com has configured their website improperly.
To protect your information from being stolen, Firefox has not connected to this Website.

cdn.astrobin.com uses an invalid security certificate.
The certificate is only valid for the following names:
*.s3.amazonawas.com, s3.amazonaws.com



Interestingly, I just got it to work by clicking the "Add Exception" box. I can now see M51, that you sent, and all the images from other astronomers. BTW, I'm using the latest version of Firefox Quantum vers. 58, on a Windows 7 machine. I did notice that it doesn't  work on my Google Chrome web browser. I get the same result as I use to get with Firefox.  By adding this exception for Astrobin, does this potentially set me up for a any possible security issues.

Thanks for any help,
