Looked through the PDF manual but couldn't zero in on anything specific. Two items here.
1. I was taking some shots of the moon last night. Camera was set on Av- 2/5 sec., f/5, 110mm, ISO 3200 (Auto). The Exposure Simulation icon was flashing. Found this in the manual but nothing why it was flashing. Did I over look something?
2. The Live View showed two vertical lines on it but they aren't on the photo in File Explorer.
As always, your help is most appreciated.
Two months ago, I couldn't spell Fotografter. Now I are one!

Hi Tintype_18, It took me several trial sessions to get my settings right for "Moon Shots". I am very inexperienced but finally, get some decent "Moon Shots". Listen to the expert advice here and keep trying.
This attached Moon Shot was taken with my EOS Rebel SL2 / EF-S18-135mm f3.5-5.6 IS STM lens at 135mm, Tv mode @ 1/1000s, f5.6, ISO 400. That seems to be my "sweet spot" for a Moon Shot" on a clear night with my 18-135 mm zoom lens. My camera was mounted on a tripod and I use a BR-E1 Bluetooth remote shutter control. This unedited image has only been cropped in Photoshop Elements to 1000px x 1000px.
