I have just got a second hand Astromaster 130EQ. I want to say that i have collimated scopes before without the use of a laser but in this case i have 2 questions as this is so far out i cant see what i am looking at half the time. So hopefully you can help, thank you. Info about the first problem: The secondary mirror fixing screw that hold the mirror and the collimation allen key bolts were so loose the secondary mirror had rolled facing the bottom of the OTE. In every other case the holding screw never needed touching and all i had to do were make small adjustments with an allen key, no screwdriver was needed. So this case is a whole different scale then any other collimation i have ever needed to do. You probably all know that i need to get the center of the eyepiece in line with the center of the mirror before can move on with this step. Question 1 What is the best way to do this, shall i just eye it for now? (i have seen people measuring to the center of the eyepiece and then do the same with mirror but then i still dont know if the mirror is facing me directly.) Info about the second problem Every other time i have collimated a scope the mirror and scope were very low quality and just used for practice basically. The old scopes were used to see if i wanted to go further into this hobby which i definitely do. Any how the old scopes had a flat mirror and i could find the center by placing the mirror on paper and tracing a circle template. The thing is this mirror is concaved so any template iswill have to be pushed into the vurve (i think). Question 2 So how can i center the mirror without placing it face down on a piece of paper which cant be a good thing? Thank you. I hope i have not gone on to much, thank you for your patience in reading a long winded post.
Hi, I recently bought Celestron Astromaster 130 EQ and I am new to astrophotography. I have Nikon D3100 and I got a T-ring and a T-adapter to get started with it but my dslr doesn't focus at all! It is really heartbreaking Can anyone please help me out with this problem? Maira
Hi everyone, I have a Celestron Astromaster 130 Newtonian scope on an EQ mount with the RA motor drive. I'm now looking to buy myself a 90GT Nexstar that will be my "shove it in the boot on the way to a meet" scope. My current scope has a quick release dovetail that makes it nice and easy to fix to the EQ mount and it looks like the 90GT has something similar. So what I want to know is whether (provided I balance the scope correctly) I can use the 130 Newtonian on the Nexstar mount at home. I'm sure there must be someone on the forum that's tried this, so if they can tell me the pitfalls to avoid I'd appreciate it.
Hi, I have always had an interest in astronomy/stargazing. Looking up into a clear night sky wondering what it would be like to be out there is always a summers night pass time favorite of mine. Although, having a high interest in this area as a child I became otherwise engaged in other activities like playing console games, and then more recently raising my own young children. However, my interest in astronomy and stargazing has since returned and I have recently wanted to begin looking into the night sky with a telescope. I am a complete novice when it comes to this and just wondered what would be a good beginners scope. I have recently been interested in buying the Celestron Astromaster 130EQ. I have read numerous reviews about this scope and everyone says that its really good scope for beginners. I have looked at images that people have taken through this scope using additional filters and lenses and I am more than impressed with what can be achieved. I am completely new to telescopes and wouldn't really know where to start. I had a low-grade telescope as a child, branded National Geographic which was great for looking at the moon with, it came with 2 lenses. I still have it but would prefer a 'more advanced', 'more profesional' scope. Any help/tips would be great. I have a maximum budget for this of £250GBP but could stretch to £300GBP Thanks all.
