The SMC in the constellation Tucanae. NGC 346 and 362 also in Tucanae. NGC 2442, a barred spiral in the flying fish constellation, Volans. I sketched this object using 4 different telescopes, from my 12.5 inch Strider up to a 20 inch Obsession. Interesting to see how much more detail emerges as aperture increases.
More favorites have to be the Dorado objects.
I observed this one from Chiefland's Astronomy Village through Tom's 36 inch Yard Scope 2 around Christmas last year. It took a couple trips south of the equator to finish this list. As one friend just mentioned, he feels an urgency to see as much as he can before it is too late. These objects are rushing from us. Our observing time is short.
