Some good seeing last Sunday, despite the heat, allowed some decent views of Mercury approaching superior conjunction and at elongation of 9ｰ. 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. Best images selected using PIPP to reduce the 257k and 140k image sets down to 26k and 14k frames then Autostakkert to take that down to 2.6k and 3.5k respectively.[Martin R Lewis: Hertfordshire United Kingdom]
