So I'm having some issues recently and have a lot of questions for the erecting eyepiece 1.5x. I want to know if they are useful, better, and i also want to know if they have a lot of detail in them. How do you use a erecting eyepiece? What is it for? When can i use it? Also my issue is when I try to use an erecting eyepiece on a star it is out of focus and cant seem to find the right focus.  yesterday I had tried on sirius but it just showed me a huge ball of light. Any help and tips will be appreciated.

The 1.5x erecting eyepiece turns the image to a fully corrected (ie: up, down, left and right as our eyes see it) view as well as acting as a 1.5x image amplifier. It is intended for terrestrial viewing rather than astro observing I believe.

Erecting eyepieces have their uses, but not many for astronomical use. The main purpose of the eyepiece is to allow you to use a telescope designed for viewing astronomical objects at night during the daytime for viewing of terrestrial objects. Astro telescopes give an inverted image, which is probably not ideal for daytime use, so the erecting eyepiece corrects this giving an upright image. Using this type of eyepiece at night serves no use because a star would look the same through either type of eyepiece.

So, if I want to observe something at daytime I use the erecting eyepiece? What should I observe at daytime? 

 

P.S: Sorry for the weird questions, I am very new to this.

Precisely. Many budget telescopes are sold with an erecting eyepiece, giving the buyer the impression that they are getting something extra. The erecting eyepieces have prisms built into then to invert the image, but the extra air/glass surfaces degrade the image. After a short while you will soon get use to viewing an inverted/flipped image so the eyepiece will get lost at the bottom of the eyepiece case.

Not astronomical targets. Landscapes, ships at sea, distant animals and birds. That sort of thing.

      Hi I am fairly new with telescopes and I noticed my telescope needed collimation. I preview the collimation at the beginning (tell me please if its alright) however after I finished the secondary mirror kept tilting and not staying in place as seen in the video. This is a Heritage 130P telescope. Please help.

      Hi,
      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.
      Critical error!
      File: ..\source\mo
      Line: 1468
      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.
      Thanks

      Hello all,
      I always been fascinated by astronomy and finally purchased a celestron nexstar 8se. Setup went smoothly but I'm a little stuck on the lens. I attached the star diagonal to the telescope and focused in on an object. I was able to see a part of the leaf on the plant in my house and I attached a picture of that. Moving the telescope left and right allowed me to see other things. I then took out the 25mm lens and can see through that when not attached to the telescope. I can see my sandals and feet through the lens and attached a picture of that. I then inserted the 25mm lens into the star diagonal and that's where all hope gets lost. I see white (assuming that's my wall) and yes the cover on the telescope is also off. No matter where I move the telescope. All I see is white. I tried last night in clear skies and pointed towards some clear stars using the skyportal app to align but I didnt see anything except pitch black through the lens. I also played with the focus but nothing. Am I doing something wrong, I would think the 25mm wouldnt be so zoomed in that I cant see anything? Thanks for any help you can provide me. Looking forward to exploring!!

      I continue my reports from observatories I have visited. This one is very special for me, I did my education in astrophysics at this place in the 1990s. My girlfriend and I took the car this weekend and visited Saltsjöbaden for a walk, only 30 km from where we live. We ended the walk up at the Stockholm's Observatory.
      Some photos from this beautiful place:

      One of the observatories at this photos is the astrograph which I already earlier had written about.
