Q: Will this fit into the svbony guide scope? the svbony guide scope is reflected and i would like to have the image flipped upright.

thanks for your question, for SV188P dielectric mirror star diagonal, it can only fit with SV198 Guide scope. here is the link: https://www.amazon.com/dp/B09C8913FZ?ref=myi_title_dp If any, please contact us through Amazon message.

Q: Svbony, is this diagonal actually painted red on the inside as some buyers indicated?

Unless there are two versions of this diagonal just know that the side panels ARE red on the outside AND inside. As some buyers report this could cause a reddish reflection that might cast a red hue onto what is being viewed, particularly brighter objects I would guess. Due to cloudiness, I haven't been able to test that possibility yet. Otherwise it's a nice 99% diagonal.

Q: Does this diagonal have a stop to keep a standard size Barlow tube from colliding with the mirror?

thanks for the question. For the SVBONY SV188P Dielectric Mirror Star Diagonal, there is no blocking thing, the end where the eyepiece or accessories are installed, there is about 45mm long installation space in the inner section, don't worry about touching the lens.

Q: "when use the sv188p with maksutov-cassegrain (mak-cass) or schmidt-cassegrain telescope, you need a special adapter." what is the needed adapter?

thanks for your question. If your telescope has a two-inch interface, you may need a 2-inch to 1.25-inch adapter ring.
