SV48P Telescope for Adults high Powered, 102mm Large Aperture F6.5 Refractor OTA for Adults Beginner Astronomer, Astronomical Telescope for Observation of Deep Space Celestial Objective

great value...optics are excellent for an acromat....focuser needed adjustments...after that..perfect

Amazing beginner scope for astrophotography . Im a beginner myself and find the scope an amazing fit for my needs. From nebula to lunar/planetary, it works great. With this scope expect a decent amount of CA (Chromatic Aberration). Not something you can fix entirely but it is possible to reduce the effects of it using filters and editing software if you’re into astrophotography. Viewing is also great! The focus controls work very well allowing you to easily fine tune the scope to your target. I would 100% recommend if you’re starting out with astrophotography and if you’re looking to play around with a beginner telescope for it. Below I’ve listed a few picture I’ve taken with the scope and DSLR. The 2 moon pictures are lucky stacked so they have lower quality. The real quality is very clean and crisp. Again just has that Chromatic aberration issue that you get with an achromatic telescope. And again i’m just a beginner at this so you could pull of some much better images with this scope!

Thank you was as advertised. Should come with a reducer. Or at least the color correction filter. With it it’s a more complete unit. I’m sure you would sell even more. Even if the price was increased a bit for the cost of the corrector it is a great deal. But either way thank you.im an SVBONY fan now and would recommend this product to anyone who asks me.

love my two scopes.I use them for astronamy and land use quality is great

This achromatic refractor is a winner. After my 3 star experience with the MK105 I was a bit skeptic but the 102mm sp48 was a different story. It arrived fast and very well packed. The overall impression was that of a well made quality instrument. The focuser worked smoothly. I set it up on one of my equatorial mounts and waited for a good clear sky night. The testing day arrived a couple of days later. My first target was the star Regulus. I used it for a star test. At low power the star looked like a bright point and the intra and extrafocal images looked good. The real test came when I increased the power to 250x using a good 2x barlow and a 4mm orthoscopic eyepiece. The star focused into a nice Airy disc surrounded by a first diffraction ring. This is waht you expect from a good refractor. Collimation was off by just a tiny bit. It was easily fixed by unscrewing a bit the objective retaining ring, tapping around the objective cell and screwing back the retaining ring but just enough for a snug fit. The telscope now showed a very nice collimation at high magnification. On the planets the telescope performed very well on the now small Mars planetary disc. It showed the polar cap and some albedo features. Not bad for an f/6.6 telescope being used at high magnification. Lunar features were crisp and clear. I could not see any violet fringing on the Moon. The star Spica showed very little violet at high power too. The fine focusing knob works great and is especially useful when using high magnification. In recent days I have been using this telescope to observe double stars. It is excellent for this purpose. I have been able to split close doubles easily at powers even above 250x. The telescope has not been tested for astrophotography yet but as a visual telescope this is a very nice instrument for the value. I read that the first batch had problems but apparently they were taken care of. This is a really good one SvBony.
