Hi everyone,
I recently bought the Sky Watcher 8-inch Dobsonian to dive into this fascinating hobby. After assembling it, I added the Baader Mark IV eyepiece along with the included Barlow lens (see attachments) and started testing by observing distant trees.
However, I noticed that the views through the eyepiece are somewhat blurry. While I can see some details of the trees, the clarity and colors are not as sharp as I expected. Interestingly, when I close one eye slightly and position it towards the bottom edge of the eyepiece, the image becomes clearer. I even managed to capture this effect with my camera, as shown in the attachments.
I also tested the preset 10mm and 25mm eyepieces and encountered the same issue. Despite collimating the telescope (see attachments) and tweaking the focuser, the problem persists.
Is it normal to get a slightly blurry image, or am I missing something? Any advice would be greatly appreciated.
