Tonight's (Jun 20-21) photo of the nova. It's still continuing to drop in brightness, and the waxing gibbous Moon isn't helping matters any by drowning out all the faint official comparison stars, and the bright ones are no longer applicable. After starhopping to the nova (marked in red) from FF Aql with a 3.5" Mak-Cass I cast around for comparison stars from my tablet, eventually selecting the ones marked in green. The top one was mag 11.3 and came and went in the moonlight. The bottom one was mag 10.7, which could be held steadily with direct vision. Somewhere in between was the nova, which could be held faintly but steadily with averted vision, so I'm calling it mag 11.0. The moonlight washed out everything fainter than mag 11.5.
The 2 images are the same image, but when you click on it one is sized to fill the screen while the other is the native size from the camera. Finding the nova is difficult, so I thought a full-sized image could help.
