I took a few pictures of the most common objects and am using a Lumix G85 with a 100-300 (200-600mm eq.) lens. That is around 2.2lbs/1kg (Yes, that is a micro four thirds sensor) together with a Omegon Mount MiniTrack LX3 Essentials. It is a very cheap mount which you have to tention manually and it only runs for 1h at a time, polar alignment is hard due to the cheap "straw" you have to look through.

I really like this hobby and want to upgrade to a newer mount and the Sky-watcher Star Adventurer GTi looks really good for the price. However, I am worried about it's max payload of just 11lbs/5kg. For me it is more than enough, but I want to know if it will be enough along the way if I upgrade to heavier camera or even a dedicated one with a proper telescope.

Can someone tell me about the Sky-watcher with a heavier load or pro-level gear on a different mount and how heavy it is and if you think this mount will be enouh for it.

How would or do you backup your home server? I don't have enough physical storage (for now) at home to store some backups, so I want to upload it to the cloud. Of course I want the backup to be encrypted, but I don't want to enter the password every time by server does a backup. I am currently using borg on my PC and do it manually. How do I create a encrypted backup without entering the key manually? Do I hardcode it somewhere? Don't really like that. I am also fine with trying other backup software.

My second (and first successful) try of the orion nebula. Any advice for editing out the noise and these stripes? What are these?

I want to upgrade my CPU in my HP ProDesk 600 G2 Mini as the current one is a little slow with 2 cores and 2 threads. I did a little bit of research and found, that my motherboard (HP KBC Version 05.39 (8169)) supports all 6th gen intels with 35 Watt TPD. Based on this, I found the i7-6700T and the i5-6500T.

This PC works for me as a home server with Minecraft at focus, maybe some Streaming service and a cloud later

I am completely new to the hardware side of PCs and don't really know if its even worth upgrading. I think the i7 is a little expensive for me, but I just want to know if both of these would fit my motherboard. Is there anything else I have to pay attention to when choosing a CPU or upgrading it?

I want to host a Vaultwarden (or Bitwarden if necessary) instance, but it keeps asking for a domain and a SSL certificate. I dont own a domain and dont want to enable port forwarding on my router to expose it to the outside.

Is it possible to host a instance only internally and access it via the IP or a domain set on my local DNS? How about SSL is it possible and/or necessary?

I recently discovered the Open Astro Tracker by OpenAstroTech. Does anyone have experience with it and can recommend it? I don't want to spend time and money for a product that maybe won't work, but I really like the idea of a self build tracker. I also like that it can be upgraded later by adding things like a autoguider

Because my camera is only ~1kg (2.2lbs) the small model is enough and I don't plan on upgrading anytime soon. If I can be sure it will work, its fine if it takes some time to print and assemble.

Also, can someone make a rough estimation of the price? On the website it is around 250€ for a complete kit, but I have a 3d printer and don't need the autoguider right now. For me that seems a little expensive for mostly 3d printed parts.

Hi, I have printed a small holder for a Bowden tube to print from my filament dryer outside of the enclosure, but the filament coming out of the tube is tensioned and I don’t know if it will cause problems later. Is this fine to keep or how can I fix this? This i a Ender 3 V3 SE btw.

I want to mount a printed part to a standard 2mm motor axis which doesn't have any dents or profile. Its just round. If I print at exactly 2mm, it fits for the first few times until it gets too lose and the spinning part sometimes falls off.

I am trying to send an email from an alias with simplelogin. I went to their website and clicked the contact link, but after sending the email, I looked in the headers and saw my real email with my real name. Is this on my side or can the recipient also see my real name? If so, how to turn this off?

I am using the Creality ender 3 v3 SE with eSuns PLA+ in black. The recommended printing temperature is 205-220 and I am printing at 210. The bed is set to 65°. When I print somewhat flat parts. The edges warp off the plate, while the printer is running and the plate is still hot. Until a few days ago it worked perfectly and I don't know what I am doing different.

It is always only the first few layers, and the print never moves, so that the printer would make spaghetti, its just the edges that lift of a few millimeters.

I am thinking about buying a home server for a wide range of things. I found some cheap old computers on amazon for around 80-90€. Is it worth it to upgrade them with another stick of ram or a larger SSD? 2 8gb RAM sticks are only around 15€, so that would be 100 in total. But my question is, is it worth it, or is the CPU the limiting factor. Some of them have one from the pentium series. Also, is 15€ for 2x8gb DDR4 RAM normal (not too cheap)? Maybe you have other ideas for a cheap home server. In my case I don't think a 90€ raspberry pi is worth it
