Maffei 2 - Galaxy through Infrared Filter

Maffei 2 is a galaxy lying in the plane of the Milky Way and is largely obscured by dust.  
Two sets of images of Maffei 2  were acquired (one set through Visual (V) and on set through Infrared (I) filter). These showed that the galaxy was visible in infrared , whilst at the same time practically invisible in visual band.

U And - Mira variable

U And (Andromeda)
U And is a mira variable with catalog period of 346.55 days  and magnitude range of +8.9 to +15.0. Baseline images were acquired in C, B, V, R & I filters Magnitude of U And is estimated at +13.9 (V band) & +11.4 (R Band)  (using the comparison star technique)

W And - Mira variable

W And (Andromeda)
W And is a Mira variable with catalog period of 395.93 days  and magnitude range of +6.7 to +14.6. Baselines images were acquired in C, B, V, R & I filters A magnitude of +7.5 (V band) is estimated for W And  using the comparison star technique.

EZ And - Mira variable

EZ And (Andromeda)

EZ And is a mira variable with catalog period of 275 days  and magnitude range of +13.2 to < +15 . Baseline Images were acquired in C, B, V, R & I filters A magnitude of +11.0 (C band) &  +12.2 (V Band) is estimated for EZ And, suggesting star is brighter than catalog magnitude, however colour dependance has not been  taken into account in method used.
