| Telescope | 22" f/4.1 equipped with a Paracorr |
| Eyepieces | 35mm Panoptic, 17mm Type 6 Nagler, 13mm Type 1 Nagler, 9mm Type 1 Nagler. |
| Filters | Lumicon O-III and UHC filters. Transparency started at 6/10 and ended at 4/10 |
| Seeing | started at 5/10 ended at 4/10 |
| Abell 20 | 22" f/4.1 (203 and 293x) - Considerably faint round even surface brightness smudge. Estimated size is about 60" across. Central star seen without O-III filter, but the nebula is still visible. |
|---|---|
| Abell 22 | 22" f/4.1 (155 and 203x) - Faint elongated patch. It appeared slightly mottled with bright spots north and SW of the center. The SW piece is about twice as large as the N piece. |
| Abel 15 | 22" f/4.1 (155, 203 and 293x) - This small, round faint planetary showed even surface brightness throughout. Estimated size is about 30" across. The central star was seen without the filter. |
| Abell 24 | 22" f/4.1 (75 and 155x) - Faint elongated smudge with a slightly mottled surface. The bright pieces were on the west and east sides with the eastern side being a tiny bit brighter. Central star was not attempted. |
| Arp 82 (NGC 2535) | 22" f/4.1 (203 and 293x) - Elongated spiral with obvious barred spiral arms. Arms are evenly bright throughout, no mottling. Arms goes around clockwise going outwards. NGC 2536 is a very small elliptical with a very condensed nucleus, almost stellar and lying about 75" SSE of NGC 2535. |
| Arp 287 (NGC 2735) | 22" f/4.1 ( 203 and 293x) - NGC 2735 shows a 3:1 elongated considerably bright patch with a brighter center. Its position angle is 90 degrees. Estimated size is about 60 x 20". It's neighbor, NGC 2735A is a very small considerably bright round disk with lying about 60" due east from NGC 2735. Apprarently Megastar has an error, it was plotted to the west versus east. A group of 4 7th to 9th magnitude stars lies south of the pair. |
| Arp 247 (IC 2338) | 22" f/4.1 ( 203 and 293x) - IC 2338 is a 3:1 elongated even surface brightness and considerably bright patch. It is about 30x10" across with a PA of 45. IC 2339 is a small round considerably bright disk lying about 90" SW of IC 2338 with a 15th magnitude star between it. IC 2341 lies about 8' almost due north of the pair. This is a very bright elongated (2:1) elliptical galaxy with a significantly brighter round nucleus. Estimated size is about 75 x 40". PA = 0 degrees. |
