Exposure times should be significantly shorter using BIN 2 vs. BIN 1, for example. The optical system is a 61mm aperture, so the light grasp is limited.
What are you imaging and how do your images look? Are you satisfied with the quality that you're getting on the BIN 1 setting?
Hopefully someone with experience using your camera will offer some insights.
Hope this helps,

If I select Bin 2 for the Rosette Nebula for example, I get 70min for Ha, 8.7hr for OIII and 43hr for SII
In Bin 1 I get 10.3hr for Ha, 112.3hr for OIII and 402hr for SII
All these selecting 15 SNR.
I have never tried Bin 2 yet for this camera but the results for Ha for the Rosette nebula in Bin 1 with Ha filter with around 7hr worth of exposures was quite acceptable.
Was not using Bin 2 because, according to the CCD suitability calculator on the astronomy tools website, in Bin 2 I will be undersampling with the camera telescope combination, and I would be spot on with Bin 1 mode.
