Comments:  NGC4565 was discovered by William Herschel in 1785.  This considerably bright, very large edge-on spiral galaxy is thought to resemble how the Milky Way galaxy would appear if viewed from outside.  The seeing and transparency were good on both nights.  In 2003 the temperature was only in the 40s, while the latest effort this year brought a cold night.  It was about 30 degrees.  The guiding was much better this year with mostly A2s on the ST-4.  To the lower right of NGC4565 it appears that the 14th magnitude galaxy NGC 4562 just registered on the film.  This faint blue smudge appeared on both negatives.
