Amazing view of the Space Station from Philip Smith in Manorville, NY on March 25, 2018
Using a Hedge HD 14" telescope with a 1.6X barlow and red Astrodon filter and a ZWO ASI290 mono camera.
Max ISS pass was 62° at 8:06pm EST.
The mount and software helped me lock onto the ISS
The seeing at the time was poor.
I centered and cropped frames but I did not stack any of these images.
I am tracking with modified EQ-G mount in Alt-AZ mod set-up
with larger motors and custom software
that is not for sale that is called Videos Sky Pro 2015.
It is the only one of it kind along with a custom pier that I can rotate the mount 360° around.
It locks onto the ISS with a different camera and the software.
I image the ISS with another software and camera for recording.
I use 2 laptops at the same time.

Origin: Philip Smith's photography of the ISS on 3-25-18 from Manorville NY, USA

Get orbital info from this webpage You will need to be inside the footprint to receive the FM signal	You can also see downlink video on this webpage
I use decoding software (TrueTTY) from this webpage Select AX.25 UHF	Example of decodes received

For my reception set-up I use the same rig as for 162 MHz AIS reception. Works OK
