That is quite the image!

Subject: [AZ-Observing] NGC 4565 with DCT
DCT telescope operator extraordinaire Andrew Hayslip took a
four-color series of NGC 4565 recently while training a
new operator. I've copied the image here:
https://urldefense.proofpoint.com/v2/url?u=ftp-3A__ftp.lowell.edu_pub_bas_Needle.jpg&d=DwIFaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=OJ27vkwFiMwZaQDu8RVFIDvaVDTI62IJ_Q8HSYFF440&m=T_W_oTdcHm9sqAig3FrBd1NMJo1lhYcHp33uZ6WiW-0&s=SMSw5cwEnT6k9MBqFklpIVWaJr2OMZZ7GHvZySBCIjs&e
Andrew sez: "The data was reduced, stacked, and colorized in
PixInsight, and comes from the B (420s x 3), V (100s x 3),
R (100s x 3), and I (100s x 3) filters."
...so more typical exposures of those with smaller telescopes,
rather than ones of just a few seconds. NGC 4565 is superposed
on a dense background of tiny, very faint galaxies, which are
visible by the thousand in this image. Not to mention the
resolved starclouds in NGC 4565 itself.
