Description

Took me a while to gather enough data to do this field any justice due to poor weather - from November to February...

I had had a go at IC443 with the Moravian in 2017 and tried again the Ha through that camera but the image is full of microlensing reflections from the bright stars Tejat Prior (Propus) and Tejat Posterior (Calx). The ASI2600MC did not suffer from those and the mosaic worked out nicely.
