i would refrain from the zoom eyepiece for AP (though it's my goto for visual), the easiest thing to do is slide the secondary closer to the primary on it's rails (just dont extend it out all of the way). A 2x barlow will work too, but it will make your field of view much smaller

Try pushing the truss in a little, and tightening the truss knobs. This will bring the focuser closer to the mirror, solving you inward focus problem.

Ahhhh, great idea. Once the weather cooperates I'll give it a try. Thanks!

I tried adjusting the truss and it worked great. Was able to snag this one once the clouds finally cleared out. My head is already swarming with ideas to make it better.

And the OneSky snares another victim!

Last night turned out surprisingly clear despite the humidity, so I took advantage of it to take the OneSky out on a quick galaxy hunt.

I had to take the secondary mirror out on this scope for cleaning. The secondary is not enclosed in a black housing like it is on my Zhumell scope.

 

After cleaning the secondary with soap and distilled water I also blackened the thick edge of the secondary mirror and also the back side. Surprisingly the collimation was not that hard after putting the mirror back. The toughest part was ensure the secondary was perfectly concentric with the helical focuser. Need to wait for couple of days for clear skies to see if blackening will make any difference in the contrast.

AWB is about to have another victim.  Too bad I'm not going to see my telescope for another couple months.  But it's ordered now!
