Thanks for the advice, I have now ordered an Astro Essentials 32mm f/4 guide scope & the ZWO ASI 120mm Mini, Here's to clear sky's!

Hello, Could someone recommend a good 5v USB power bank suitable for powering my SA2i (5v usb) & two dew heater straps (5v usb)? From user experiences how long would, say a 10,000 or 20,000 mHa unit typically supply power to these type of devices?

Hello, I am a photographer with over forty years experience (now retired) BUT very little knowledge in astrophotography! So I am looking for some advice from you please. I am using an Olympus OMD EM1x & EM1Mkll with a 300mm f4 mounted to the Sky-Watcher Star Adventure 2i. I have now realised I need a guide scope to allow longer exposures so are looking at a 30mm f4 (120mmFl) or should I go up to a 50mm (180/200mmFl)? Is it worth the extra for the ZWO ASI 120mm mini-S which is USB3.0 and twice the fps over the 120mm mini USB 2.0 or would I not notice any benefits with my setup? Any advice & constructive criticism welcomed. I have attached a copy of my first attempt which has inspired me greatly! Single image processed in LR & PS. 300mmf4, 1600 ISO, 120sec.
