I got tired of HT Cas, and move on MT Cas. MT Cas is not much observed..
In VSP there is no ref stars in photometry table to MT Cas, so I pick out near by TYC 3657-1980-1 to be as ref star ( 12.58 V-mag ).
On the basis of single 8 hous run , 867 measurement, TYC 3657-1980-1 seems changes quite rapidly, according to Peranso analysis 1.636 h. "Singin" like uning fork!
I used 30cmF4 Newton, MX716 ccd , V-filter (Baader) and 25sek exposure time.
As a bonus, in minima of MT Cas lightcurve, is shown little bump, real or not?
Both are very interesting stars!
How and where I can find is TYC 3657-1980-1 ( Epoch: 2000.0 RA: 00h14m38.334s DE:+54?40'29.66") classified as a variable?
