NGC 4535 & NGC 4526

Recommended Posts

A lovely clear night revealed two new objects (well, new to me anyway - they are in fact ancient :icon_biggrin:). On the left of the image is NGC 4535 (also known as McLeish's Object according to Stellarium), a barred spiral galaxy located some 54 million light years from Earth in the constellation Virgo.  On the right of the image is NGC 4526 (according to Stellarium it is also known as the Lost Galaxy), a lenticular galaxy in the Virgo constellation that is seen nearly edge-on. 

These two objects were chosen more or less at random while searching around in Stellarium for an interesting target to image. I really wasn't expecting NGC 4535 to resolve at all, hardly anything of it was visible in the subs so I was very pleasantly surprised to see its beautiful spiral arms come out so clearly. At 54 million light years from Earth it's the most distant object I've imaged to date and it needed the 2 hours and 40 minutes of exposure it was given.
