Observer’s Challenge: Galaxy M98 in Virgo – May 2017 – Report #99

Image of galaxy M98:  32-inch reflector by Mario Motta from Massachusetts.   


M98 is one of the fainter of the Messier objects and can be especially difficult when observed with a telescope smaller than 4-inches. The surface brightness is very low, and regardless of telescope size, a dark sky is needed to see and fully appreciate the many faint, but fine details this galaxy has to offer.

In a 10-inch reflector, M98 appears fairly bright, elongated, a bright nucleus, with unevenness in the halo, with some mottling noted in the central region. Two brighter sections can be seen in both the NW and SE arms.  The nucleus is off-set toward the SE.  

With a 102 mm refractor, and observing from my moderately light polluted backyard this galaxy appears very faint, elongated and weak without any center brightness. In a 6-inch reflector, the galaxy is slightly enlarged and overall a bit brighter when compared to the refractor.  Roger Ivester – Observer from North Carolina
