The first object is identified as FSR2007-0541 (l = 126.66⁰, b = -0.76⁰; α2000 = 01h23m06s, δ2000 = 61d51m23s). It lies in the direction of Cassiopeia constellation. Although it appears as a dark nebula in the optical wavelengths, several stars are seen in the infrared wavelengths. We obtained the data in JHKs filters from 2MASS and plotted the colour-magnitude diagrams of stars with good photometric quality. By fitting the theoretical isochrones to JHKs color-magnitude diagrams we estimated the interstellar reddening to be E(J-H) = 0.4±0.05 mag, obtained the distance as 2.4 ±0.5 kpc and found the log(age) to be 8. The second object is identified as G169.857+1.925 (l = 169.857⁰, b = 1.925⁰; α2000 = 05h27m08s, δ2000 = 38d31m16s). It appears as a small group of stars embedded in a cloud. The analysis colour-magnitude diagram for this object yielded an interstellar reddening value of E(J-H) = 0.45±0.05 mag, the distance as 5.84±0.5 kpc, and log(age) of 7. Both of clusters appear to be deeply reddened in the optical wavelengths and may contain many young stellar objects. |
