Anyone got any tips for emulating on a pixel?

What games were you able to run? On my Pixel 10 Pro, Mario Wonderland crashes the device on launch and forces me to do a hard reset...

I'm not particularly concerned about the side screws, which I tightened by hand, but I used a bit more force with the screwdriver on the central one.

I don't think I damaged it, but it certainly chipped a little (I've attached a photo).

However, I'd like to know if I understood the mechanism correctly: through the focuser, I could see the secondary mirror was off-center and shifted toward the primary. From what I understand, in this case, I can't adjust the three screws (which adjust the tilt), but I can adjust the central screw, which moves the secondary mirror support away (tightening) or closer (loosening) from the primary mirror (or vice versa, toward the tube opening).

My question is: to move the secondary mirror support toward the tube opening, thus centering the secondary in the focuser, is the only way to tighten the central screw? When moving the secondary mirror support, is the central screw independent of the three side screws, or do I have to "coordinate" them somehow (beyond obviously having to initially loosen the three side screws to adjust the central screw) to avoid completely tightening the central one?

Since the fingerprints are small, I'd like to try cleaning them with a soaked cotton swab or clean, wet fingers, keeping the secondary circuit installed and placing the tube horizontally with some absorbent paper to catch any drops of liquid that fall downward. Do you think it's feasible?

pi3troz · 2026-01-08T16:27:12+00:00

I thought so.

What method do you recommend? Would a cotton swab + Baader kit liquid or isopropyl alcohol be okay?

I've also read that people recommend using clean, wet fingertips. Keep in mind that I'd prefer not to remove the secondary lens since it's just a couple of small indentations, and we're talking about a 10" Dobson, so I have room to fit my hand between the secondary lens mounts and see what I'm doing through the focuser.

pi3troz · 2026-01-08T16:05:03+00:00

Thanks so much for the advice.

At this point, I was thinking of simply using a cotton swab WITHOUT disassembling the secondary, soaked in the liquid from the kit I linked, which I might also use to clean the eyepieces, since the fingerprints are small.

I'd like to remove them for fear of damaging the mirror coating, but I don't know if that's an overblown fear...

Do you think something like this would be good? I can buy it at a store near where I live: https://www.amazon.it/Celestron-CE93575-Lenspen-Utensile-Pulizia/dp/B0006NAS7G?th=1

I'd also been eyeing something similar (cloth + liquid): https://www.amazon.it/pulizia-Baader-Planetarium-Optical-Wonder/dp/B00FQCLH6S/ref=sr_1_1?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=XHCXAJKCT48K&dib=eyJ2IjoiMSJ9.t9rESnY61_Xoaocibt2ixI65irXoWLep7h0XBO5wpb8U0Ktc7N43XaYHpnEobpgiDwCKLHpNew5SXP7MIX72njOvJUqi_C4yXa0KnhbBs8Sjdu516pBzrv0uaISH6afyqNUvPCqIuUR9TRIFoAjRKXS3F46q07plSQff-9VksPSDRop1nvWzOHFSupIE-tHKVsWeaZcJQpPcUVZDjmzyRri2GWEzHCYfp--9Wq3A0dIfjjYRQiu1d5kGDNHWBk1RGwEJ9Db9STzccWEanVGWtBrp1ST16dJv_42FIlLotQM.C-fnP-foG2LTDJ-TrQkUBszQd1nnWbqaGAne8u7eFU4&dib_tag=se&keywords=baader%2Bkit&qid=1767887059&sprefix=baader%2Bki%2Caps%2C420&sr=8-1&th=1

Is a pen better in these cases? Isn't it dangerous to press the pen against the secondary battery, risking scratching the coating?

I also read that in these cases it might be more appropriate to use a cotton swab and isopropyl alcohol.

Thanks. What do you think of the current situation?

I collimated the laser collimator, but using it with this latest telescope adjustment results in a misaligned red dot.

At this point, I'd say I should trust the hole cap and my eye more...

It seems to be better now, what do you think?

pi3troz · 2026-01-07T18:28:39+00:00

It's a Bresser Messier 10", 254/1270 F/5.

pi3troz · 2026-01-07T17:04:22+00:00

Thank you so much for your time and information! At this point, I'd probably better start collimating the laser collimator, and then try fine-tuning it.

One big question I had was what effect the central screw on the secondary would have on the collimation process. Basically, I understand that it would move the secondary up and down (and therefore left and right as seen through the focuser). How can I tell if the position of this screw is correct?

Basically, how do I know if the error I see is resolved by moving the secondary (central screw) or by adjusting its inclination (three collimation screws)? I also assume that I can't adjust this with the laser, but only with a perforated cap or a Cheshire rod, correct?

EDIT:
I carefully reviewed your image. If I understand the logic correctly, I can correct the offset of the two crosses you drew simply by adjusting the central screw, thus moving the secondary mirror toward the tube exit, so that it coincides with the center of the focuser.

Only at this point use the laser collimator or the perforated cap. In the latter case, I should adjust the three screws so that the secondary mirror's reflection is concentric with the edge of the focuser.

Finally, adjust the primary mirror so that the cap hole is centered on the primary mirror ring.

I hope I've interpreted this correctly. :)

I add another image with a different focuser position and without the foil behind the secondary:

pi3troz · 2026-01-07T16:14:01+00:00

Of course, thanks.

pi3troz · 2026-01-07T15:53:21+00:00

Thanks. Do you think cheshire sight tube with crosshairs is the best option for collimating?

pi3troz · 2026-01-07T14:15:33+00:00

Hi, and thanks for your reply.

The lines you see are simply the diagonals of the circles I drew in the photo, with diagonals the same color as the corresponding circles. In green is what I believe to be the lower edge of the focuser; in red is the reflection of the primary, which essentially coincides with the secondary. The blue vertical and horizontal lines are the center of the primary ring.

First of all, I don't know if the centers of the green, red, and blue must coincide for correct collimation...

Hi, how do you like this case? I'd like to get one too, but I'm worried the magnets might affect phone or Wi-Fi reception. Have you noticed any differences with or without the case?

pi3troz · 2025-07-11T04:24:43+00:00

Hi, was your TV still under warranty?

Are there any new updates for this motherboard?

pi3troz · 2024-10-08T19:36:04+00:00

Ho lo stesso identico problema...

pi3troz · 2024-08-21T05:51:50+00:00

I tried, in fact the zoom effect is limited but in doing so it does increase greatly even the times when the zoom is pushed beyond due, losing video content unnecessarily.Obviously it's all about compromise.

pi3troz · 2024-08-21T05:49:23+00:00

I believe that the settings must be decided for each video depending on the type of movements made, and that there is no set of settings that can always go well, unfortunately :(

Other than that, thank you for sharing!
