First thing to get is the adaptor like this one -
https://www.bintelshop.com.au/Product.aspx?ID=5558 you will need to confirm connectivity to your camera, Canon and Nikon are the 2 most popular so there is something for nearly all models, Pentax not sure.
Second you will need -

You are then ready for prime focus photgraphy which is the clearest way to image.
One thing to be careful of is your scope as this method make back focus quite long and it may not be possible to acheive focus. In my case my DOB can a screw 1.25" adaptor that allow the adptor the first item to conenct directly to the 1.25" adaptor. My back focus is acheivable but only have a few mm left of travel.
Using both items you will need a barlow, not a powermate as a Barlow will acheive focus better. A powermate from what I read does not alter the back focus (In Theory).
My next purchace is a powermate and will prove is disprove this theory.
Finally you will more than likely not acheive the best image taking snapshots of Venus because it is close to rising heat from the sun rising and will cause massive atmospheric turblence in the image. High Frame rate (10FPS and higher) would acheive better images after processing.
The above setup will allow you to attempt deepsky as long as you have a stable mount for long exposures.
Seeing you have the camera, have a good time, it is adictive.
Good luck
