> I literally have maybe 15 or 20 dollars left You might wanna consider the JJC BTR-N1 Bluetooth Remote Control as a cheaper alternative, but make sure your firmware is updated. Honestly, just use the 2-second self-timer... it's free and stops shake.

Regarding what #1 said about "Be careful, the D3500 lacks a remote port..." - that is such a massive point to keep in mind! Are you already using a solid tripod for those star photos? Honestly, you should try the SnapBridge app first since its a fantastic free way to trigger the shutter! If that feels too clunky, maybe keep an eye out for a cheap used Nikon ML-L7 Bluetooth Remote Control.

Ngl, I'm still so bummed out that Nikon stripped the remote port off these newer entry-level bodies. I've been shooting with their gear for over a decade and it was such a letdown when they made that change. I actually had a pretty frustrating experience trying to do long exposures on a trip a while back... my phone battery died because of the cold and SnapBridge just refused to connect, so I basically missed the window for the shots I wanted. It's definitely not as reliable as the old wired remotes used to be. If you're really tight on cash but want a physical button, maybe look into the PHOLSY Wireless Bluetooth Remote Control for Nikon. It's usually around 18 dollars so it should fit your budget perfectly. It's a bit of a plastic-y feel but it beats using a touchscreen in the dark. Just make sure you pair it before you leave the house because trying to sync Bluetooth in the pitch black while your hands are shaking is a total nightmare. You can do it tho, just takes a bit of patience with the setup!

Be careful, the D3500 lacks a remote port for cables. I would suggest the Aodelan Bluetooth Remote Control ML-L7 since it's cheap and actually compatible, unlike most generic ones you'll find.

Came here to say the same thing lol. Great minds think alike I guess.

I just stumbled on this thread and honestly I've been dealing with the exact same issue for about two months now. The technical limitation of the D3500 lacking a dedicated MC-DC2 accessory terminal is a massive hurdle for long exposure stability. I've spent way too much time looking at wiring diagrams and compatibility charts only to realize most budget options rely on that missing port. It is incredibly frustrating that there isn't a straightforward, low-cost hardware solution for this specific body. I still havent found anything that fits the budget while maintaining a reliable connection for star shots.

@Reply #5 - good point! Honestly its just so disappointing that Nikon took the accessory port off the D3500. I've had issues with the wireless connection dropping out in the field before, and it really ruins the mood when you're trying to capture the Milky Way. Basically, since you cant use a wired clicker, you're stuck with Bluetooth or the app as the others mentioned. Here are a few ways to handle it on your budget:

• Use the built-in self-timer set to 5 or 10 seconds. It costs zero dollars and is actually more reliable than a cheap remote that might lose its pairing right when you need it.
• If you really want a hardware button, check out the PHOLSY Wireless Remote Control Bluetooth. It's usually a bit cheaper than the official Nikon branded stuff.
• Keep an eye out for a used Vello FreeWave Bluetooth Remote for Nikon on the forums or eBay, sometimes you can snag them for under twenty bucks. It's a bit of a workaround for sure, but you'll get the hang of it. Just make sure your camera firmware is updated or the Bluetooth might act wonky... the stars out there are definitely worth the hassle tho.
