NGC 3628 -- Spiral Galaxy in Leo466 viewsNGC 3628, a spiral galaxy in the constellation of Leo, and one of the Leo Triplet galaxies. This image is my first CCD image from Lake Riverside. The conditions -- high wind that came up after midnight -- limited the total exposure time. Processed in Maxim DL, CCD Stack, PixInsight, and Photoshop.Apr 13, 2008

Sunspot 987372 viewsSunspot 987 of cycle 23. Taken just as clouds were coming in, with winds occasionally jostling the scope. Processed in Registax and PixInsight. The primary contrast adjustment/sharpening was with wavelets, and I used gaussian wavelets and a linear progression.Mar 29, 2008

Mare Nectaris462 viewsMare Nectaris, taken a few days after the new Moon. Fracastorius crater is the large crater at the bottom of the mare, crater Rosse is the small crater in the mare. This is a mosaic of two shots, combined in Photoshop and processed in PixInsight. The image was upsampled by 2x at the start of processing. Selection of the resampling algorithm was critical -- bilinear and even bi-cubic bi-spline added noise, cubic bi-spline had its problems but was the best overall.Mar 15, 2008

Crater Gassendi390 viewsCrater Gassendi, taken a few days after the first quarter Moon. Aligned and stacked in Registax, two versions of sharpening using deconvolution and wavelets in PixInsight. The two versions were combined in Photoshop.Mar 13, 2008
