  1. Welcome! I am sure you will get lots of good advices from the forums :-)

  6. Hi! Based on the listed focal length and tube length, I think the Astromaster 114EQ has a built-in barlow. So, I am not sure how an additional barlow will work in such optical system and how much it will affect the optical quality. Your 10mm eyepiece is giving you 100x. I would suggest you get a 6~7mm eyepiece of basic Plossl design such as the Celestron Omni. This will get you to around 140~160x. Beyond this, you would need better than average atmospheric seeing, a very stable mount, precisely collimated optics...etc. Just a few tips from my limited experience: - keep the object (mostly a planet) at the centre for the best optical quality, even a basic Kellner/Modified Achromatic should perform quite well at the centre. - you need to be patient to obtain the focus at high magnification especially when you have a less-then-perfect focuser. - even they might be manufactured from the same factory, the same eyepiece branded under Celestron/Orion seems to have better quality-control then the brand-x one.
  7. At that price, I would suggest: - a 60mm or 70mm refractor, easier to maintain and to aim at objects plus no need for collimation. - the ones from Meade and Orion have a red-dot finder which will be MUCH more useful then the single-element, dim, narrow-field 5x24mm that comes with the Celestron equivalents - personally, I would prefer a long focal length one rather than a short-tube. Economical optics performs better at slower focal-ratio, and for the moons and the planets (which are prime objects for scopes like these), a 70x given by the stock 10mm eyepiece is better than the 40x on a short-tube using the same eyepiece. - unfortunately, at that price range, your alt-azimuth mount would probably has only vertical slow-motion only. An AZ-3 mount equipped 70mm refractor would cost around 50% more. Hope these helps.
  8. NexStar 130SLT has a focal length of 650mm and a fast (f/5) mirror. To raise your magnification from 72x (using your stock 9mm modified achromatic) to around 108x, you need a 6mm eyepiece. Given the fast focal ratio of your mirror, I would suggest a basic Plossl. You might be tempted to go for a 5mm or a 4mm, but you need better than average atmospheric seeing to enjoy the higher magnifications. To more tips from my experience: - keep the object (mostly a planet) at the centre for the best optical quality, even a basic Kellner/Modified Achromatic should perform quite well at the centre. - you need to be patient to obtain the focus at high magnification especially when you have a less-then-perfect focuser. - even they might be manufactured from the same factory, the same eyepiece branded under Celestron/Orion seems to have better quality-control then the brand-x one.
  9. Hi! Everyone, Just picked up an old hobby and looking forward to meet new friends around the world. I only have two small telescopes... Celestron 70mm f5.7, red-dot finder, star-diagonal, backup optical finder made from binocular objective Omcon Plossl 25mm, 10mm; Brandon 8mm; Celestron/Vixen Ortho 6mm (.96" converted to 1.25") 25-Yr. Old 60mm f12, 6x30mm finder, mounting rings with piggy-back mount Celestron/Vixen Kellner 40mm; Celestron MA 10mm (1.25" converted to .96") Skywatcher EQ-1 with Celestron R.A. Drive Clear Skies!!!
