yes, the 25mm will give you smaller views, the 10mm more close up views.
What is the focal length of your 8" saxon, 1000mm?
divide 1000mm by 25mm = 40 x magnification
divide 1000mm by 10mm = 100 x magnification
Also have you got enough saved for a Universal Digiscoping Adapter $69 plus freight. It will make taking pics thru the eyepiece of the telescope much easier.

is great for knowing what is in the sky and identifying objects.
Venus is very bright in the west, Jupiter is very low in the west once the sun has gone down, Mars is rising in the east at 10:50 tonight, Saturn 4am.
If you can see the southern cross in the south and also the two really bright stars a bit above the cross, can you see the that one of these really bright ones is a double star?
Your 10mm should be able to show you the double!
