My other half bought me (us) a Celestron 130 for my birthday recently.
I have watched tutorials and done a lot of reading about collimating and various other tips since alongside several hours peering through the telescope.
I can achieve a very crisp image of the moon which is awesome. However, trying to get a decent focus on Mars/Jupiter Saturn is proving very frustrating. The only non-blurred image of any of them is a single white-point, non dissimilar to what I can see via the naked eye.
i’ve tried both the 20mm & 10mm lenses and adjusted the focus in and out all the way.
Any advice would be gratefully received.
thank you, in advance.
I would like to ask you if you have any advice, comments or thoughts on my storage proceedure that I propose to use for Cubble, my CPC1100.
My overall golden rule, and I think it is for most telescope owners, is to try and avoid large shifts between OTA (although being a CPC it's OTA + double fork arm assembly + motors) temperature and that of the ambient / outdoor temperature. This applies especially in the summer, avoiding bringing the OTA from an air conditioned house (EG ~ 70f ) to the outdoors where it can be 85f - 100f where I live. That amount of temperature shift is enough to cause condensation on the mirrors - ask me how I know In the winter, it's the way around, where you ideally want to avoid bringing a very cold OTA (EG 45f) into a house where it's 65f - 75f. So I am trying to apply the lessons I have learnt and formulate a storage procedure for Cubble.
If the weather is set clear / dry for a few days, I will end my observing session by wrapping Cubble in an Arcturus waterproof / thermal sheet with another waterproof cover placed over that. This has worked very well thus far.
I am lucky that I have an outside shed close to my observing location. The weather is getting cold enough now that I want to avoid bringing Cubble back into the relatively much warmer house. So he's going into the shed. For this, I have to remove his OTA / double forks from the tripod and then store that part separately in the shed. For ease of thinking, just assume that the shed temperature is very close to that of outdoor (+ / - 5f)
So this is where my questions arise - I will be storing his OTA / fork / motor assembly (henceforth = OTA) on a sturdy table in the shed.
1. Is there a best position for this? I.E. should I have the primary mirror facing down toward the corrector plate or the other way around? I've had a look online and opinion seems split on this. Note - in the hot summer months I will will store his OTA in either the horizontal position (I.E. perpendicular to the azimuth clutch) to avoid the scary possibility of grease dripping the primary to the secondary.
2. Is there any reason - aside from stability - why I shouldn't store his OTA in the horizontal / perpendicular position? His OTA is balanced well enough for me to put the OTA in that position with the altitude clutch very loose without the OTA moving.
3. Talking of clutches - irrespective of which way I store the OTA, does having the clutches loose or snugged tight make any real difference? Some people say it puts strain on the motors doing that - but how is that any different to an observing session?? Because in an observing the motors have a chance to move around? The CPC owners manual isn't much help, it just mentions to leave the clutches loose when transporting the OTA.
4. Do the answers to the above questions depend on how long he would be stored for? I anticipate not having him in the shed for more than a week at a time before bringing him out for use.
Note - One position that has been suggested by some people is to lay the OTA on its side.. I want to try and avoid this if possible and also avoid the use of storage case. For my purposes, please just assume the double forks will be upright and the only thing left to decide is whether to have the OTA perpendicular to the azimuth clutch, facing the clutch with secondary mirror or have the primary mirror end facing the azimuth clutch.
Thanks for any advice / thoughts / comments. All are graciously welcomed.
I am hoping someone here may be able to offer some help or advice. I have submitted a support ticket with Celestron but I am still waiting for a reply and would really like to get this working ready for the next clear sky!
I recently brought a starsense but have not been able to use it because it comes up with the following errors,
Err: Model Num
The telescope model could not be read and initialization cannot proceed.
An unexpected error occurred that may cause the HC to not opperate normally.
When updating the controller and camera it finishes succesfully but when I check for new updates it proceeds to install the same one again and again.
I can still control the mount and I think the camera tried to do an alignment in my room.
I have a Celestron Nexstar 6SE.
Just thought I'd share this in case you haven't seen it already. A recent (September 2020) article added to the Celestron 'Knowledge Base' on collimating SCTs.
I don't claim to have seen all articles on collimation, but this is defs one of the best that I have seen.
