Hey everyone, I just purchased my first refractor telescope but I have no idea where to get started, let’s get right into what my problem is. I purchased a Celestron C4-R; model number 21016; this came with a bunch of little pieces that I don’t know what they do, it’s a refractor telescope. I have the star diagonal but I don’t know where to attach it. I just want to know what I have to do to have it ready to be used thank you I would like help asap thank you👍🏼👍🏼👍🏼
I measured my setup times when i did my last imaging run. Absolutely shocking 🤔
Step 1: unmount 8" quattro, disassemble EQ6 into 3 parts, move parts to terrace and reassemble EQ6, remount 8", without counterweights: 6 minutes 50 seconds (correct position marked on terrace, with right arm hurt, good time )
Step 2: Mount counterweights and set scope to park position: 1 minute 55 secs
Step 3: Connect power sources and connect all cabling: 20 minutes
Step 4: get the computer and software running (on a very good night): 10 minutes
Step 5: Let my old QHY8 cam and the scope cool down: 1 hour - otherwise i get strong gradients!
Total prep time: 1 hour 39 minutes. Obviously, the cable time could be improved massively by training. But even if we could get the cabling time to zero, i'd get only down to 1h24', with the total time being dominated by the cooling of my rig.
Open question: As i would not leave my cam outside, there seems no real possibly to cut down significantly on my prep time, even with a small obsy? Or am i doing something wrong?
P.S.: Getting an expensive cam is right now no good option

Hi. Just starting to use autofocus with the Celestron motor focus and SGP. Can anyone give me some starting points for step size, backlash etc. I’m getting there but wasting a lot of imaging time just trying to get this to work accurately. I’m currently trying a step size of 75 and a backlash of 50. Any tips most appreciated.
If I am just generally looking through my telescope and find something interesting which is not near any identifiable object. Is there a simple way that I can save the position where my scope is pointing so that I can perhaps continue viewing the following night. Perhaps using a cell phone or other attachment, Some are so small that it is not visible through my finder scope. I have the Skywatcher 8" on a Dobsonian mount.
