My understanding is the filters in the Tamron are part of the optical system, so the clear filter must be used if not using the color ones.
Some of your photos look unfocused and others look like lens or camera shake.

Jack,
I think you might get better results if you raise your iso. There is a trade off here between shutter speed and iso.

Moon tonight. Left this in color.

If bringing the camera outside from an air conditioned or heated room, the lens needs to settle down to the outside temp. It’s a relatively small lens compared to telescopes, but it helps to let them settle to the outside temp.
This one was shot in the late afternoon and the sky was blue. Less contrast to deal with. Sometimes the atmosphere has too much temperature variations at different altitudes, and under those “seeing conditions” it’s much harder to get a good shot. Think of looking down a long asphalt highway on a really hot day, and how the image shimmers above it due to the heat. I suspect the atmosphere is more stable well after nightfall or during the day, less so at sunset or sunrise.
You’ll also get a better image when the moon is high up in the sky, when it’s low on the horizon you are looking through much more of the atmosphere, with more temperature fluctuations. Having the fixed display on the back of the Q makes it really tough to shoot straight overhead.
I have a magnifier attached to the back of the Q-S1 to help focus on the rear display, and use the camera’s zoom in on focus mode and have the focus highlight turned off. I just focus by what looks sharpest to my eye. Set the camera to the lowest iso, this was iso 100, 1/250 sec exposure using 2 sec shutter delay. I took about 10 shots and refocused every 2-3, and chose the best one to edit.
I used Lr to edit with a B&W Profile. I just play with all the sliders to get a black sky and brighten up the light areas. You can also adjust the color temperature and tint sliders as it will alter the brightness/contrast of the B&W image. I ended up not using much sharpening, whatever I tried looked bad. You can also adjust clarity and dehaze to get more detail, but it’s easy to go over board.
I’m certainly no expert at this, but hope it helps.

Mmm, I’m clearly not a fan of those images.

Thanks! Yes, it’s converted to b&w. I’ll try a re-edit and see what I can do keeping it in color.

Shot low in the sky in some haze.
Pentax Q-S1 w/Tamron 55B SP 500mm/8, no crop. The Q-S1 has a crop factor of 4.65 = 2,325mm equivalent focal length.
I look forward to trying this combo when the moon isn't so full.

It is really nice having the tripod mount, quickly able to level the lens, or rotate to portrait position.

Thanks!
Your pics on the review page helped me determine this had the sliding hood before purchase. The give away was the orientation of “Tamron SP” on the hood.

Reading this thread helped me decide to purchase a near mint Tamron 55B SP 500mm/8 in case with filters. This one has a slide out hood and the tripod mount. I’ve been very pleased with it’s performance. Here are some shots using different non-Pentax cameras:
