I had a go last night from my backyard in Sydney. Saturday's jaunt to the Mountains ended up clouded out,
.
I managed a 1.5hr session until the dew put an end to things, so I didn't manage to complete the list.
Leo Triplet: surpisingly easy to find even though it lies directly over the lights of Sydney's CBD from my place. M65 and M66 easy enough to see with their bright cores and fading elongated bodies. I found M66 particularly beautiful, not as stark as M104, but I think I like it more, giving hints of structure in the disk through my 17.5". NGC 3628 proved too illusive last night. Thought I caught a hint of it, but can't say for certain. I try again during the week. The picture of the system on Wikipeadia I'll use as a reference as the M65, M66 and the bright star to their left, all fall within the FOV of a low power EP, switching EP's to mid power showed them up better and the details began to resolve.
NGC 5170: Too hard to find in Sydney skies, even with my 17.5". Right spot, maybe, just maybe a very faint ghostly glow, but I'd say no.
Hickson 62: Like the Leo Triplet, two I was able to spot, the third not. Again, Sydney skies too bright. Being eliptical galaxies, the show up as soft oval glows.
NGC 5128: Once you've located it, its dark band is unmistakeable, separating the two lobes. In my 17.5" at 133X, the wedge like shape of the band is quite distinct, with a streeky nature to it, an the superimposed stars seen in photos of it, easy to see. Would be nice to chase it down again from better skies.
NGC 3109: Right on Zenith for me last night, last object and too hard to star hop to for me at 11pm after a big weekend, and the dew had started to settle. Next time.
Coal Sack: Caught it on Saturday night as the only object I was able to see through the sucker holes. So striking and eerie against to soft glow of the Milky Way.
NGC 2438, chased it down two months ago in three scopes, an 8"f/4, a 10" f/5, and 13.1" f/4.5 so I guess it doesn't count for April's Challenge. What I will say though is that it was much brighter in the smaller, but fast focal ratio 8" than the 10 and 13.1. Fast focal ratios are a plus when viewing some objects, like nebulae, from light polluted area, especially when combined with a nebula filter. Small, but easy to see Planetary Nebula.
My effort for April.
Mental.
