Four comets night

#1

Post by Bigzmey »


01/23/2022

Location: home, Bortle 6.0
Equipment: SW 180mm Mak and Stelarvue 102ED on iOptron AZMP. EPs: Baader Aspheric 36mm, TV Panoptic 27mm, TV Delites set, TV Plossl 32mm, ES62 26mm.

The light pollution is pretty bad at my home location, so I mostly focus on doubles when observing from here. However, inspired by recent comet hunting report from Shelby I decided to catch a few myself. For the most parts Sky Safari does poor job estimating comets brightness, so for my selection of targets I rely on Comet Chasing/Skyhound.

Comets
19P/Borrelly – 9.2 mag comet in Cetus. It was easily spotted in both 180mm Mak/Aspheric 36mm (75x) and SV102/Delite 18.2mm (39x). Bright stellar nucleus and faint coma were reviled in both scopes. Mak has also resolved a faint tail. This comet is near maximum brightness now, perfect time to catch it.

104P/Kowal – 11.5 mag comet in Cetus. Very faint spot with averted vision in 180mm Mak/Panoptic 27mm (100x), confirmed with Delite 18.2mm (148x).

4P/Faye – 12.5 mag comet in Monoceros – FAIL. I got unlucky with this one. It was only 6” from 13.3 mag field star. I could not tell if I see the comet, the star or both together unresolved.

29P/Schwassmann-Wachmann – 11.5 mag comet in Taurus. The comet was pretty much at zenith, but the AZMP mount has handled it nicely. Very faint small round fuzzy in 180mm Mak/Delite 15mm (180x).

6P/d’Arrest – 11.1 mag comet in Cetus. Faint fuzzy star in 180mm Mak/Delite 13mm (208x).

It took about 80 minutes to hunt those comets down, but it was totally worth it.

Monoceros doubles
STF 823 – 8.9, 9.7, 7.5”, yellow, white – SV102/Delite 11mm (65x), 180mm Mak/TV Plossl 32mm (84x). Both scopes have framed this double nicely.

BNW 4 – 8.0, 10.8, 46.7”, white, gun metal – nice contrast in 180mm Mak/TV Plossl 32mm (84x).
STF 869 – 8.2, 9.1, 24.6”, pale yellow, white – better presented in SV102/ES26 (27x) vs Mak/TV Plossl 32mm (84x).

BU 567 – 6.0, 10, 4.2”, white, white – kept pushing power in 180mm Mak until with Delite 5mm (540x) the dim secondary was resolved. The view was fuzzy due to poor seeing but smaller blob sitting next to larger was unmistakable.

BAL 319 - 8.9, 10.3, 5.6”, white, silver – split with some black in the middle with 180mm Mak/Delite 15mm (180x).
J 53 AC – 7.0, 10.7, 34.6”, yellow, gun metal - Mak/TV Plossl 32mm (84x).
STF 911 – 8.7, 9.0, 11.7”, orange pair - better presented in SV102/Delite 15mm (48x) vs Mak/TV Plossl 32mm (84x).

BAL 1695 – 6.2, 10.4, 19.4” – the main was of rich copper color in both scopes. It took some elbowing to squeeze out grayish secondary with averted vision using 180mm Mak/Delite 9mm (300x).

STT 142 – 7.1, 10.6, 8.2” – once again had to push power with 180mm Mak/Delite 5mm (540x) to resolve dim fuzzy secondary next to the bright bluish main.

BAL 63 – 7.1, 11, 12.6” – another one of those close uneven pairs. Dim blurry secondary was resolved next to the bright orange main with averted vision with 180mm Mak/Delite 5mm (540x).

STF 920 – 7.4, 10.2, 12, ab9.5”, ac 30.7”, white, silver, gray – AB was an easy split with 180mm Mak/TV Plossl 32mm (84x). Dim fuzzy dot of C was resolved with averted vision with 180mm Mak/Delite 5mm (540x).

HJ 731 – 8.9, 10, 11.4”, white, silver – easy split with 180mm Mak/TV Plossl 32mm.

This 180mm SW Gregory Mak is really great on doubles. It amazes me how it handles high powers even under bad conditions.

Outrageous evening Bigz!!!!!

I know that you love Anza, but that is quite an amazing sky adventure you had!

"STT 142 – 7.1, 10.6, 8.2” – once again had to push power with 180mm Mak/Delite 5mm (540x) to resolve dim fuzzy secondary next to the bright bluish main".

Whaaaaat!!!! 540x!!!!! Awesome!!!

Thanks for sharing your wonderful evening and congratulations on the apod!

Thanks Jim!!! :D Fanny that you brought it up, but during this session I had the same sense of tranquility I typically get at Anza. Could be crisp night air, or less noise from the streets, or the fact that beautiful patterns of winter constellations have enough bright stars to look good even in Bortle 6.0 sky.

Great report! Very well done on those comets - I found too they take a long time to observe especially when the conditions (LP) are not ideal.

Thanks Dave! I hope you have a chance soon. What mount for SVX127?

Laziness. :lol: At this point I have SV102ED and 7" Mak perfectly aligned and balanced on my AZMP mount. If I would substitute 7" Mak with 8" or 9.25" SCT for the evening I would spent about an hour for adjustments and then would have to do it again to put 7" Mak back. Besides, I was pretty sure that 7" should be enough aperture at least for comet detection. I was right although it would be easier with 9.25".
