  1. Well finally I've had a non-cloudy/rainy night (albeit with nearly full moon) to give a good long test drive of my new (well 2nd hand bargain) Astromaster 130EQ out and I had fun with it and managed to get reasonable views of the Moon, Betelguese (didn't blow up), Pleides, M42 (practically compulsory I bet everyone goes for this 1st time out!) and Venus (bright but boring - not unexpectedably). Overall I'm reasonably pleased given the price I paid. I loved the view I got of the southern highlands on the moon and crater rims just peaking over the leading limb! I had the expected issues with the bog standard RDF that comes fitted but will just have to wait until the Rigel I've ordered arrives to get any improvement over that. A few queries/ niggles have arised after this first viewing session:- 1) The slow mo controls feel a bit "gritty" and un-smooth, particularly the RA adjustment - can anyone point me in the direction of a good tutorial on giving these a bit of a service or what may be causing this? The RA seemd to have a bit of a "bounce" in it and when adjusted seemed to go briefly in the opposite direction before jerking back to moving prograde (if that's the word! - I mean following the earth's rotation in the RA axis) 2) I'm aware the mount that comes with this scope is not the best - is the scope worth upgrading to a better mount in future? or would I be looking at replacing both the OTA and the mount, particularly if I wanted to move into astrophotography? (this would be quite a while down the line when budget allows). I guess what I'm asking is would the scope reward getting a decent mount when I've saved my pennies? and then afterwards maybe replacing the tube itself? I know I'd need at least a tracking motor to start with to get longer exposures... 3) Any tips and tricks for a fast but accurate polar alignment? I just kind of did it by eye last night and it was good enough for what I was looking at (I think I'll need to sort the issues with the slo mo controls first to be able to judge how accurately I've aligned) Strap a laser pointer to the polar axis? 4) I've found I've been using the scope with the tripod legs not at full extension as it seemed a little wobbly - this does lead to some rather unusual viewing positions however... Any ideas if I might be doing something wrong here? 5) Collimation - I have a laser collimator but with there being no centre point marked on the primary have no real way to check the secondary - any hints and tips here? The scope seems to be in good order anyway so maybe no rush to dive into this for now. Thanks in advance for any replies I may be away from the computer for a few hours from now so please excuse any slow responses/thanks
  2. I have Celestron AstroMaster 130 eq. I know how to attach the motor driver, too. I want to dive into astrophotography. But I don't know: How can I accurate polar align my telescope, if it doesn't have any polar scope? I think drift polar-alignment is very hard. Is there any other way? How fast must be the motor driver's speed if I don't have polar-aligned telescope yet? I am buying my new Orion StarShoot G4 Monochrome Deep Space Imaging Camera. Is it good that I attach Orion camera on Celestron telescope? I want to buy ZWO 1.25" LRGB Imaging Filter Set. Is it good to attach ZWO on Orion and Celestron? Is it a good choice to select these machines? And finally: is Celestron AstroMaster 130 eq telescope good enough for astro imaging? (I want to image DSO objects.) Thank you for your effort and time. Clear skies!
  3. Hi, I just bought my first telescope, but I really can't see anything but black. I tried a few things mentioned on previous posts, but still all I can see is black. What am I doing wrong? Thank you all for your help.
