Good detail in Eta can be caputered with 3 minute exposures.
20-30 longer exposures are all you need.
An EQ6 properly aligned (drift) should be able to track well unguided for around 3 minutes or more. If you know of someone with experience drift aligning seek their help (me I cheat using a guide scope SSAG camera)
Don't forget darks and flats as well
