I've never seen the HH in my 10", even under the dark skies of Trout Lake in November, during new moon. I knew I was looking right at it, and I also know it's a larger object than most people realize. Still, I could not see it. I could see the Flame nebula quite easily as it was obvious, but not the HH. I didn't have a H-beta filter though. It was an exercise in futility, trying to spot the HH on that night even though I knew it was in the FOV of the EP. Just wasn't at all visible.
When the BIL saw the central star, he said there is dot in the middle of smoky ring. What was surprising to me, is that I didn't tell him about a central star. I told him to look for a smoky ring. I can't see the central star at home. But in the skies of North ML, I could. It was extremely faint and did not resemble a pinpoint star but more a ghostly dot.
Also, M57 was right at zenith on the nights I observed it in ML which helps mitigate seeing conditions some.
Novice when it comes to observing astronomical objects, but not when it comes using scopes. He lived in Alaska and often used spotting scopes on top of rifles for hunting so he is well practiced in using optics to look at objects. That said, out of my two BILs that looked through my scope that night, he was only one to notice the central star in M57. My other BIL (and my BIL's brother) could not see it.
Where do you set up in Trout Lake? Private land, or is there a good place to set up open to the public? I've set up on the Conboy Lake wildlife refuge east of Trout Lake a few times but it's always windy there and technically I don't think it's open after dark.
Had I read your review back when the A11 first came out I may have bought one but the price has gone up nearly $400 since then and that's all I paid for my ES 12mm 92 in 2019 on a 20% off sale before the price of those went up. I have seen the HH with it though, but in a 20" with an Astronomik h-beta filter. The h-beta filter makes a lot of difference on the HH. I've never seen M57 central star but seeing is rarely great under the jet stream and I have trouble getting the 20" mirror to cool down in the summer.
