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👍🏼👍🏼👍🏼

Hello and welcome to the forum.

This link should be the instruction manual that covers your scope:

Feel free to ask questions if things are still unclear.

Hey there John, thank you for the fast response, I read the manual however I can’t manage to setup the eyepiece on the star diagonal. I posted some pictures of what I have, I don’t know how I need to put together all that or where those things go on the telescope, thank you!

Theres a loose screw on barrel next to your 32mm eyepiece, try to screw that onto the star diagonal then place that barrel into the focuser making sure to fasten it inplace using the locking screw then place any eyepiece into the diagonal again securing it inplace with the locking screw/nut.

 

On closer inspection 😛 that barrel/nosepiece may be from the 32mm eyepiece.

On even closer inspection 😛 I see a machine thread coming out of your longest eyepiece/barlow,  it's possible that the nosepiece of the diagonal is inside (it's sat next to the diagonal in the image)...

Okok thank you! the nose piece was able to go In the 32mm, and then I attached it onto the star diagonal, is this correct?

The diagonal should look like this:

The nosepiece may be inside the long thing in image 1 :)

Just be careful not to force any threads together whilst your finding your feet.

Ok I think that's for attaching to a camera, your looking for a small nosepiece/barrel with a suitable thread that fits into the diagonal. If your unsuccesful today in finding the attachment you could try what's called "straight through" viewing this way you wont need the diagonal but it will be akward looking at high elevations.

Just place an eyepiece directly into the telescopes focuser.

That is part of the finder scope. Lots missing there including the objective lens !

I think the silver barrel for the diagonal might be stuffed into the barlow lens that you have.

Ohhh okok so that means that I can’t use the star diagonal?

If you can get the silver barrel out of the top of the barlow lens, it may well screw into the diagonal  then you can use it.

It’s a little too small for the entrance of the diagonal, does that mean I can’t use it?

The ones I have didn’t seem to fit, how would I do the straight through method you stated?

The proper nosepiece should thread on and feel secure and not screw on so far as to scratch the small mirror. If your not sure about using the diagonal for now you can try just attaching an eyepiece directly to the telescope.

Where I’m at supposedly Jupiter is going to be more visible than other times, which one (from the picture that has everything) could I use to get an ok view of it?

Put the 32mm eyepiece into the focuser and secure the screws then wind the focuser  until the thing your looking at comes into focus 😛 OK I'm off for now good luck in your endeavours and I'll look for your updates tomorrow, welcome to SGL!!

Hi

Is there a thread on the inside of the diagonal that can attach to your telescope, I can't quite tell from the photo, normally as John showed you, the diagonal show have a silver nose piece that slots inside the scope. But yours may screw on but kit sure, I'm only just looking at thus quickly before work and haven't looked at your many yet. Edit.........If you look on your case there's a sliver short barrel nose piece with a thread on it screw that silver barrel into the diagonal where there's a little thread, then your diagonal should look like the picture John showed you and then sorted 👍

That's the nosepiece for the 32mm.

I think the nosepiece is stuck in that barlow.

Well it looks like you have the nose piece for the diagonal missing, you can still use the scope looking straight through but going to be awkward. Your going have to look for a 2" diagonal now something like this if money is tight there are more expensive ones but this will easily do the job.https://www.firstlightoptics.com/diagonals/skywatcher-90-erecting-prism.html

Let me know if you need a 2-1.25mm adapter something like this I will send you one. https://www.firstlightoptics.com/adapters/baader-2-to-125-reducer-adapter.html

Isn't that the objective end of the finder? It has a rubber o-ring (albeit a little frayed)

and finder eyepiece:

This is a great game!

      The focuser on my SkyWatcher 150i is a basic rack-and-pinion, unsurprising for the price point, but sometimes a bit of a pain to control finely enough. I’m not looking to spend any serious money upgrading it, but I did want to see what I could tweak.

      The first thing I did was to slacken off (slightly) the screws holding the plate against the spindle, as the operation was very tight when new – that helped a bit (and I think that without doing this first, the “friction fit” approach described below wouldn’t have worked). I will eventually get around to taking it all off as per AstroBaby's tune-up.

      Improving the fine control without a major change means doing something with the focusing knobs – they’re quite small, so the effective “gearing ratio” when you operate them is on the harsh side. Some folk have described fitting larger diameter replacements, either bought or made, and even using ones with a planetary-style mechanism to achieve a reduction in the ratio. I didn’t fancy this, as I couldn’t see how the existing knobs were attached to the spindle without trying to prise them apart (possibly terminally). The other option is to increase the effective diameter of the existing knobs, for which purpose a clothes peg is apparently quite popular, but I’ve also come across descriptions of chop sticks inserted into holes drilled at intervals into the circumference, and punctured lids from peanut butter jars.

      I wanted something that was cheap, relatively tidy and non-destructive. The answer seemed to be some sort of thick sleeve that I could fit over the knob. It would need to be a tight fit so as not to slip in use, to be not so large as to foul against either the focuser tube or the main OTA, and to be thick enough that it didn’t flex sideways when grasped. I thought I might find some larger rubber washers that would do the job, but none were thick enough to be rigid in use. However, a bit of searching found these spacers that are apparently used in vehicle shock absorbers.

      My calipers said the diameter of the focuser knobs was around 29.5mm, and the nearest spacers that were available had an internal hole 30mm and outside diameter 60mm. I ordered one that was 10mm thick, not quite as deep as the knobs, but which allowed a bit more space on the inside edge for free operation. I’d hoped the internal hole might be a but undersized when it arrived but it was spot on, so I wound five or six turns of masking tape around the knob first. To avoid taking the tape off when fitting the spacer, I positioned one side first and stretched it across the face as I pushed. When it’s flush with the knob’s outer face, it’s just clear of the focuser body and OTA. There might be enough room to stick some kind of friction surface around the outside to improve the grip, but I don’t think it’s going to be necessary.

      I decided to do only the one knob, so I now have a very Noddy “dual speed” affair.  Because the clearances around the fitted spacer are quite tight, it’s worth checking the positioning of the spindle in the focuser body first – mine was fractionally off centre, so there was more room one side than the other (assuming you have no preference).

      Hi,
      Now, I know that Cubble likes to keep fit. I try to keep all of my telescopes healthy and feed them only the best planets and DSOs. 
      But - why is that Cubble just LOVES to go all around the houses on some of his GOTOs?! Talk about taking the long way home!!!  I could have sworn that I had 'Cordwrap' set to 'Off'............. 
      I have set Cubs up with a totally cordfree / wire free system and therefore find this going 340 degrees around to an object that is 10 degrees away incredibly annoying and time wasting.  
      Well, I think I may have found the answer today. Some of you may already know this but for those that don't, I hope it helps relieve some of your frustration. 
      What I disovered is that the Star Sense hand controller resets the Cordwrap setting (MENU>>>TELESCOPE>>>CORDWRAP) back to 'ON' each time a new alignment is completed. So, one can spend time seemingly making sure that it is set to 'OFF' (if that's the setting you want, of course) only to find that once you have completed an alignment, the hand controller defaults the Cordwrap setting back to 'ON'.
      So, if you don't want or need Cordwrap set to 'ON', make sure you change the setting after completing each new alignment.

      Hello,
      I know you've seen these questions a lot (unless your new) but I'm struggling a lot on if I should buy a Skywatcher 250px (10") or 200px (8") (dobsonians). I have a 5 inch and i'm looking for a big step up for noticeable changes. 
      Thank you

      Hello, all ~
      If you'd please take a moment to read the info in my profile, I'd be grateful beyond words. In short,, I leaped into this new passion before fully researching all of it's necessary aspects. I'm determined to verify with my own eyes the deep cosmos and better understand the far past & distant future events. Thanks so much for indulging this newbie.

      Hello,
      Does anyone know if I should upgrade my telescope? I have a Celestron Nextar 127slt and I've been using it for a few years now. I want to see more detail on Jupiter, Saturn and Mars.
      Does anyone have any suggestions from Celestron?
      Kind Regards
