Bresser Spezial Astro 25x70 vs Bresser Hunter zoom 8-24x50.
In my opinion both magnify less than stated, the power of Spezial Astro is about 23x and the power of Hunter zoom is about 22x.
Don't forget to set the quality of image at 720p if you want to see a similar view to the view in the eyepieces.
The image seen directly though eyepieces is alwas better.
They both are ok for their price, Bresser Spezial Astro is about 10% sharper and 20% brighter but more expensive and bulky, not good to take for a walk. Bresser Hunter zoom is lighter, smaller cheaper and thank to zoom function at the magnification of 10x has got much wider field of view and good eyerelief with a bright sharp image but at full power its eyerelief isn't good and it's hard to have a sharp image in both eyepieces.
