Now, you hopefully didn't spend all your money?
Next step is power (power supply or suitable battery), plus a heater controller plus heater strap for the eyepiece. Maybe heating on the Secondary mirror as well. Oh, and a heater strap or two on the finderscope as well!
And has anyone mentioned adding an Argo Navis telescope-pointing system?
Keep your "cooling" fan running all through the session (check no vibration is seen in the image). It can help prevent dew formation on the primary mirror which will happen in very humid conditions.
