SvBony SV705c Planetary Camera Review

[@kevinhutchinson8129]

Very nice review and commentary. I just purchased the SV705c with UV-IR cut filter and plan on using it with SVBony's recommended setup of the SV550 80mm F6 telescope (with field flattener) and their filter wheel, which I also own. My question to you is: What Imaging/Guiding (control) software setup do you use? Are you using PHD2 and N.I.N.A? Or? Thanks!

[@AmatureAstronomer]

Thanks. Sounds like you have a nice rig. I do EAA. I use Sharp Cap Pro. Nothing else. No guidance. No post processing. I do 4 to 8 second sub exposures at 120 to 250 gain. I have three motorized GO TO mounts, all of which use Synscan and are controlled with my cellphone. I control the cameras from my front room with a long 30' or 50' cable. I use either my 305, 705c, 405cc or 605cc camera. I have not reviewed the latter two, yet. I have about a dozen refractors, including an SVBony 80mm ED refractor, several of which I have reviewed. I use a Founders generic 0.8 reducer\corrector for all my refractors with a two inch focuser, except for my Celestron 102mm XLT f/10. I am currently using my Orion 130mm Spaceprobe Newtonian and Celestron 150mm XLT Newtonian preparing a video with photos for each along with a review of the 150mm. Once I finish with the Newtonians, I plan on using my Celestron C6-A XLT Schmidt Cassegrain with Hyperstar 4.

Thank you very much for your reply! As I'm fairly new to astrophotography, I've pretty much stuck with SVBONY's line of scopes. I think you get a lot of bang for the buck with them. Aside from the 80mm F6, I also have their SV503 102mm F7 ED Achromat and their SV550 122mm F7 APO Triplet, both of which I like a lot. I run it all on an EQ6-Pro using an ASIAIR. I did just purchase SVBONY's new SV555 Petzval, which I haven't received yet, but am really looking forward to trying out. As I'm looking to the SV555 to be a great "grab and go" scope, I'm probably going to want to look at getting a lighter mount setup. Any recommendations you'd care to share?

[@AmatureAstronomer]

You do get a good bang for the buck with SvBony products. I am elderly, feeble and have a bad back. My primary mount is the medium Celestron CG-4 mount with an added Astro-Gadget GO TO motorized conversion kit. The EQ6-Pro is too heavy for me to drag out into the back garden. I also have a Sky Watcher Star Adventurer GTi computerized equatorial mount which is rather light and can handle an 11 pound pound payload. I often use it for my SvBony 80mm ED and am certain it could handle a SV555 Petzval.

Shows that you can get images of the brighter deep sky objects with a planetary camera.

[@AmatureAstronomer]

Yup. On dimmer objects, as well. My current problem is that in my Bortle 6 sky with an average FWHM of 6-8 (very poor seeing) and a line of trees surrounding my house which limits me to about 3 hours a night the only way I can collect enough data to get good photographs is to take subs on several nights, which I do not do. I have a lot of telescopes and am currently using my 150mm Newtonian. Once I get enough photos to do a review and video of photos, I will be switching to my Celestron C6-A XLT Schmidt Cassegrain and Hyperstar 6 v4. At f/2, I should be able to take photos in 3 hours that might take 36.75 hours using a typical f/7 APO.

[@thecampingastronomer8554]

@AmatureAstronomer you sound similar to me. I am Bortle 5/6, with trees, houses and streetlights limiting my viewing window to about 3 hours max. Like you, I don't do multiple night sessions either.

Hi, Great reviev, and I also have the sv705c. What size is the celestron you have on the az-gti back of you ?

[@AmatureAstronomer]

It is the optical tube from a Celestron 6SE. I do not have the mount for that scope. I also have a Celestron 6-A XLT, which is the same thing but black. I use my Hyperstar 6 v4 with the black one. Six inch is the largest Schmidt Cassegrain or Newtonian I own, because I am elderly and feeble. I think the most popular SCT is 8" and many folks have 9.25" or larger.

[@frzguida]

Well i think 8" is the best, but if you havent a fixed place where observe should be tedious to set and unset when weather is good. I have the az-gti too and searching a not weight telescope fot it.

[@AmatureAstronomer]

I use my Celestron short tube 80 (f/5) with it. I also sometimes use my Celestron 6" SCT with it, as it can handle 6 pounds plus SvBony 705c camera. The 8" is stronger (and heavier), but the Hyperstar for it costs $1000 and for the 6" only $400.
