SVBONY SV193 2" 0.8X Reducer Field Flattener for SV503 102ED Scope
Guter Korrektor für Astrofotografie Entgegen vieler Empfehlungen, dass dieser Reducer nur für SVBony Teleskop 102 funktioniert, macht er auch bei meinem 80ED einen guten Job. In der Beschreibung steht ja auch, dass er für verschiedene Teleskop und Brennweiten eingesetzt werden kann. Dass diese nicht unbedingt Hersteller konform sein müssen und IMHO dieses Teil auch in den gängigen Astroshops unter einem anderen Namen verfügbar ist, habe ich es mal gekauft und probiert. Mein Exemplar glättet und reduziert auf alle Fälle mit einem Sky Watcher 80ED absolut zufrieden stellend. Sensorgröße bis ein Zoll, kein Problem, APS-C habe ich noch nicht probiert. Für mich eine klare Kaufempfehlung!

It works as described I'm getting amazing pictures utilizing this with the SVBony a 70 mm scope. I would really love to see them come up with a harmonic drive mount.

SVBONY SV193 2" 0.8X Reducer Field Flattener for SV503 102ED Scope
It does flatten the picture as long as... The flatner works well when not adding anything between the flatner and the dslr camera. On a CCD you will need a 55mm space between the camera sensor and the flatner. DSLR camera already measure 55mm so just the flatner is the only thing needed. The flatner was made for small sensor like the one that comes with the ccd cameras so a little bit of egg shape stars might still form. You might need to process the stars with a lens distortion tool in adobe.

A "Must Have" accessory if you have the SVBONY SV503 70ED or the 80ED RefractorA "Must Have" accessory if you have the SVBONY SV503 70ED or the 80ED Refractor This is a "must have" for the SVBONY SV503 80ED and the 70ED. On the 70ED telescope, it drops the focal ratio from f/6 to f/4.8 for a wider field of view and slightly brighter (faster) image. With the 70ED, I was able to get the entire Pleiades cluster on my ZWO ASI183MC Pro camera sensor with almost zero vignetting.

Excelente, pero... Me llego manchado. Nada que no se solucionara con una mi kit de limpieza de lentes, pero igual es algo raro para algo nuevo. Asumo error en el control de calidad del producto. De ahi en fuera funciona perfecto.

Excelente producto Complemento para el telescopio Svbony SV503 80mm, monto el aplanador de campo y me ayudó a enfocar los objetos de corta distancía al menos de unos 2Km. Espero complementar la información en los comentarios del telescopio propio ya haciendo pruebas de observación de espacio profundo. Pero excelente compra.

Not Five Stars by Far..Not Five Stars by Far.. Not happy at all. You can definitely see the stars in all four corners look like eggs. When you look at a non cropped picture like my Christmas Tree star cluster and Cone Nebula shot you can see what I’m talking about. I do not recommend. I also had a sv503 that I purchased that the whole focuser just came loose during a session. I walked out to check on my rig and noticed that the camera was completely sideways. You could literally wobble the focuser back and forth. I purchased the ATO and reducer back in September and only got to use it a handful of times. I’d recommend maybe saving a couple bucks and purchase something of more reliable quality. When I contacted customer support. All they did was send me a couple of screenshots and an explanation of what a retaining thumbscrew was used for and after a couple of emails svbony dropped the ball on me. Not happy but lessons learned trying to save a couple of bucks.

This also works with the SV550This also works with the SV550 This is advertised as being for the SV503 but, with an additional spacer, it works well with my 550.
