Mercury (IR) 25th August 2019

685nm IR filter
642nm filter for IR
ASI290MM
Some good seeing yesterday despite the heat allowed some decent views of Mercury approaching superior conjunction and at elongation of 9°. Two independent sets of data, one with a 685nm IR filter and one with a 642nm IR filter show very similar appearance. Messenger data also for comparison.
