I've asked for better comparison stars for PZ Cas some time ago and CT Lac (nearer bright comp. stars) just recently. Both sequences have improved much to my regard.
Because both stars are (relatively) good observed, this post is maybe a good way to draw attention to this circumstance.
I want to use this opportunity also, to thank the AAVSO staff for their always very fast work. It's impressing to see how things are today - back in the 90s? Blue prints - often very old- then Guide..........? Today you ask for a new sequence or improvement of one and very soon your request is settled - well, was there a little problem with HV Cyg? No, in fact it needed - how many? - years till a sequence for this star was available? This can happen, but I'm always impressed how fast everything becomes done today - thanks again to all from the AAVSO who make - and made - this possible!
