A bit of backstory:
Recently, the basement in my house in Chicago was flooded, and my mom and I flew out to assess the damage and attempt to fix it (we hadn't lived there in a while). Long story short, I was cleaning out the basement when I discovered a Celestron Nexstar SLT 114, a telescope gifted to me when I was far too young to operate it. I've spent the past few days attempting to restore it to working condition.
My basement was submerged a few inches deep in water, so thankfully the telescope tube, although a bit dusty, was completely unharmed, along with the motorized mount. However, that's really my only saving grace. Below are a few of the complications I've had so far:
Alongside my telescope, I also received one of those fancy celestron lens kits. This has been since lost to time (believe me I looked), as such, the only lens I currently have with my telescope is a 4mm one, along with a 23mm one I recently purchased off of Amazon. The 4mm I found in the focusing tube when I dug it out of the basement, which isn't surprising as younger me fell for the classic blunder "more magnification = better." I've considered buying more lenses but I wanted to make this post first because I'm trying not to spend to much money.
The bottom of the remote was submerged in water. The LCD was impossible with only a few select pixels working, however the arrow keys were still working, so I assumed it was fully functional. I know it was the remote because I've tried it on the AUX and HAND CONTROL ports of my telescope with the exact same result. I attempted to clean the PCB of the remote in order to potentially restore the rest of the LCD, and ended up breaking it entirely. I have already ordered a replacement off of eBay, but that wont be here for a week, so I would like to get some kind of jank setup working in order to use the dang thing.
I suspected my younger self screwed around with the alignment without knowing what the knobs on the back actually were, and sure enough, upon a quick test run pointed at the moon, my picture was very fuzzy. I know there are many different guides out there, but most videos and posts I read work with Primary mirrors with the little Collimation doughnuts in the middle, which mine doesn't have. Due to me losing all the accessories for the telescope, I have no tools in order to Collimate, not even a cap. I've read that laser collimation can be janky, that the cheshire ones require the doughnut thing, and I also read online that my telescope has a 2x barlow built into the focusing tube, and I'm really not in the mood to screw around with that if I have other alternatives. Also, since I don't have a working remote, I can only tilt my telescope up and down, not side to side (I have to physically re-position the telescope) which is very clunky and makes it impossible to reliably aim at something. So what are my options in terms of collimation (I'm open to taking it to a store and having them do it if that sort of thing exists) and how do I carry out those options?
- I cannot move my telescope due to a broken remote
- I only have 23mm and 4mm lenses, no other eyepieces of any kind
- How do I collimate it with no materials, and no collimation doughnut on my primary mirror?
- What other accessories do I NEED to buy in order to have a good time? (I've already ordered a new remote, ETA 1 Week)
- Is there a cheap way to connect the PC to the telescope without a working remote? (Sub $50)
- What software on PC should I get to maintain and use the telescope? (I currently have the Celestron Firmware Manager, NexRemote and Stellarium)
- What are some methods to use my telescope until my new remote arrives
- I ordered the exact same remote I originally had, but are the new ones with USBs compatible with my telescope?
