i would like to use my bino to watch star clusters and nebulas - galaxies ( if i can ). i dont want to see planet details with my bino.
basically low power scanning and watching stuff from my window and carrying it in occasional camping spots. i will make a d114 f900 telescope within next few months, so something to complement this telescope.
there are two (at least) different moments in your words and these are two different purposes - so the equipment best suitable for it must be different as well (there's no one-for-all optical instrument).
1) you gonna use binoculars according the formula: "binoculars & telescope as a pair".
so your binoculars gonna be kinda finder. the role is not usual for binoculars, but this doesn't mean they can't be used that way; this means that you can't put usual criteria for astro-binoculars on the basis of your choice.
the primary criteria here should be binocular' weight (yes - the weight).
choose models no more than 0.5 kg. you got it right - this is about using by hands (no tripod). that's why recommendations here for compact binos were not so irrelevant.
secondary criteria is field of view. the more is the angle - the better. it shouldn't be less than 7.5 (8 - 9 is perfect).
and trietary criteria is magnification. don't go higher than 7.
2) binoculars for watching the sky objects between scope sessions
here everything is standart: take the bigger aperture and the higher magnification your budget comply.
P.S.: but I would recommend to you buy a 2.1x42 model as a first binoculars
