New Comments and Sharing about SV48P Recently
The SV48P, one telescope we released a year ago. As our older telescope, it has some improvements on the basis of SV48. Its performance is relatively simple. Compared with the latest SV550 or the classic SV503, it may not perform well in some aspects, but it seems to have brought some new surprises to those who own it recently, especially for beginners.
We have compiled some feedback about it, hoping to serve as a reference.

My first Solar register of 2023. Very happy with the outcome and my SV 48P performance in conjunction with my brand New SV 705C. Used a baaderish white filter in front and a Baader Solar Continuum. Used a UV IR Cut Svbony filter too.
First time stacking and editing a full moon shot from this last week. Used PIPP, AutoStakkert3, and GIMP. Comments or criticisms welcome.

My last photo for 2022: Horsehead and Flame nebula and Alnitak out of control here, hah. The sky has been mostly cloudy for the last six weeks, so I've only just been able to figure out guiding and using my AsiAir Pro properly.
I'm super happy with this one, and intend to clean it up with more data and calibration photos in the new year. Happy new year all!

M45 taken in early November. This was taken with my first refractor (SVBONY SV48P), Canon 6D, SW Star Adventurer 2i. No guiding, no filters. I don't remember the number of exposures, 800 ISO from Bortle 5 backyard.
The SV48P offers a lot of bang for buck. So far I am super excited to get out and take photos with it, and it is so rewarding to do so. I finally spent some time taking a proper photo because we had really clear skies for the first time in weeks, and I noticed an optical aberration - the stars had halos. Take note that I use narrow-band filters, so it's not CA.
I found that the objective lens edges are not blackened (Svbony, if you can, blacken the lens edges for new SV48Ps). So I took the risk and blackened the lens edges. The halo did improve, but it looked more like a ring. I did some experimenting and found that it is truly in focus when I see the ring. My suspicion was that the lens spacer was causing this ring - the spacer is transparent, and it is visible in the optical path. So I made a mask which has an inner diameter of 85mm which covers the lens spacer, and the ring is now gone.
I highly recommend making such a mask and giving it a try. I've had one printed now, which I will fix on permanently." ----Marc Klynhans
Q:What are the outstanding features of the upgraded sv48p?
Toothed focusing knob
Dual speed still, but this time you will find the toothed knob on the scope just you did on our star product SV503. The touch matters in our opinion. These pairs of toothed focusing knobs would make you feel more pleased when you view the night sky with naked eyes. The targets have been located but somehow we just couldn’t make it clear, that might be the last thing we wish to happen in this hobby. So we keep the dual-speed focusing system which makes the whole process easier and smoother and we truly believe that you would love it.
We want to achieve a good balance between damping and smoothness with this tiny brass focus plate. So now, a 13mm brass plate under the focusing tube, provides comfortable damping to secure the process of focusing stable and accurate, which means deviation or shaking of the focusing tube, or the inconsistency of the hand feel during the whole operation of the focusing will not be the pain again.
360 rotatable R&P focuser
A rotatable focuser would greatly help you get just the right position for your camera or diagonal without touching multiple screws which could be pretty annoying to the final image. Just loosen the knob on the tube a little bit then you could just rotate the whole focuser, simple and clean.
Mounting rings with a 130mm dovetail plate
A longer dovetail plate than the original SV48 which has a 100mm dovetail plate gives you more space for the mounting, with the fine-made mounting rings together making sure your telescope is steady.
Q：Hello, does this only bring the telescope or does it have other accessories? Can I use it directly after buying it? Do I need to buy other accessories?
A:Package includes SV48P 90500 Astronomical Telescope OTA,2" -1.25" Adapter,Finder Scope Bracket,Lens Cover,1.25" Dust Cover,130mm Dovetail Mounting Plate with Tube Ring
No included diagonal, eyepieces and a tripod etc.
Q：The description has two different weights how much does it actually weigh？
Q：What type of glass is used in the objective?
A：Fully multil green coated lens; fitted with achromatic glass for good edge-to-edge viewing; fully multi green coated lens maximize light transmission eliminating false color.
Q：are the rings felt lined?
A：Sorry it doesn't, the bracket is fixed on the lens barrel with screws and is detachable.
Q：Is the metal loop telescope holder removable, if is is, how do you remove it?
A：Yes, you can remove it by turning the screws on the bottom of the stand.
Q：How to get started with Astrophotography?
A: Firstly, you needchoose a telescope.For beginner astronomers, a refractor is the betterbeginner telescope for astrophotography.
Designed for Camera photography
Loosenthe screw that fixes the focuser on the telescope, the focuser canrotate 360 degrees.When you use the camera, you don't need to unscrewthe camera to adjust the angle.You only need to loosen the screws,adjust the camera angle, and then tighten the screws.
