Hi, I am new and have tried to observe now for multiple weeks. I have got some good viewing of the moon but I have yet to see any of the other planets, they are all just over bright white dots.
I am in a 5 bartle zone.
Heritage 150p
Bewinner 1.25" Astronomy Telescope 4 Piece Eyepiece Kit, FMC Eyepiece Kit 6MM/9MM/15MM/20mm for Telescope, FMC 68 Degree Ultra Wide Long Eye Relief Eyepiece https://a.co/d/9XPZjaK
Svbony filter kit, using a svbony UHC filter.
What am I doing wrong? Tried with the different color filters as well.
please help, about to give up 😇

I am bringing some people over to the premier viewing with my new telescope. Hoping for the best experience, what colour filter could potentially help with the viewing of the comet that is discussed these days, c/2022
Please help me make it the best experience it can be for everyone 😇

Svbony has this blurb on that linked ad for the CPL filter:
CPL filter is mainly used for elimination of polarized; and enhances the contrast of the moon and planets in photographic images
Visually, I can't think of any use for a CPL filter in astronomy. A variable polarizing filter is handy to vary the brightness of objects. This can be useful for the moon, Jupiter, Mars, and Venus. However, these filters are actually two linear polarizers back-to-back with a swivel attachment between them.
A CPL or circular polarizer is used in photography to cut through polarized reflections such as from a glass or water surface to image what lies beyond. The circular part returns the light to being non-polarized after passing through the linear polarizer part, thus they can only be used in one orientation, linear polarizer facing the object. This circular step is needed because polarized light really messes with light sensors inside the camera that are sensitive to polarized light.
Svbony should have just included a tradition neutral density moon filter instead. These cut the brightness of objects by a fixed amount (generally 13% transmission or 87% attenuation) without changing the color balance.
Thanks, hopefully the rest of the filter will aid me in normal viewing. Do you think I should invest in a CLS filter. I think that broader band works good, I am in 5 bartle zone.

There's no CLS filter in the Svbony 7 filter set. There's a CPL, or circular polarizer. Is that what you meant?
It doesn't matter what order you stack them in.
The Moon filter is actually a Moon & Skyglow (M&SG) filter. It's a generic neodymium filter. When combined with a light yellow filter such as a #8, you will get an approximation of the Baader Contrast Booster. The #12 in the set will cut out practically all blue light, while the #8 will cut mostly violet let, leaving most blue light.
If you have bought a separate CLS filter, it is basically a wider band-pass version of a UHC filter to combat light pollution and to slightly enhance the visibility of nebula. I'm not aware of any useful color filter combinations with the CLS filter.
You are absolutely correct sir. It says CPL on it. What is the big difference? I can really only find compares between UHD and CLS. Thanks!

Hello! Just got the svbony 7 filter set. I noticed that you can insert filter in sequence. Is it a good idea to always add the CLS filter?
Let's say together with the moon filter.
If so, does it matter if it comes first or last from the telescopes mirrors side?
Thanks 🙏

....and you'll probably find it with another ten names. Svbony and presumably Bewinner just market series of EPs etc made by a few Chinese optics companies. That's why you'll often get people just calling them 'redlines', 'goldlines', etc.
I see, even if they could be manufactured at different sites, is there any indication that the build quality of them would be different?

Hi, I found this kit with a OK price. The brand is Bewinner but they look so similar to the svbony UW series.
Anyone know if it's just a branding change for another region or such?

Great thanks guys! Especially my wife will appreciate these answers. (She said the same) 🤣🤣

Hi, I am a total newbie and and ordered my first ever telescope for me and my daughter. I heard that the eyepieces that comes with scope are usually not the best and I have heard quite a bit about the BST line, as well as Svbony red and X-cel.
Reading up here on the forum it really sound line BST gives most bang for buck.
So my question is what I should complement with. I guess I should start out with some kind of shotgun approach and get a bit of everything to find what we enjoy.
What mm would you recommend?
I am thinking I should get a 5mm, but maybe a 8mm + Barlow (which I probably want anyway) gives me more view options.
Thanks!

I am using the skywalk 2 app to navigate myself, sure I can definitely be off and point at the wrong thing. To me the skywalk map is a little bit off, today for example I could clearly see Orions belt, 3 district dots with lots or room between, but in the app they where so close it looked like only 2 dots (until I zoomed in)
