Comets, Galaxies and Callisto transit.

Location: Anza desert site, Bortle 4.
Equipment: Celestron 9.25” Edge HD SCT and Stellarvue 102ED on SW SkyTee 2 manual AltAz mount.

7/8/2020

NEOWISE comet is all the news now. Unfortunately, it is hiding behind the mountains to the east presently. However, there were a couple of other comets accessible with binos or small scopes:

C/2019 U6 (Lemmon) – comet in Leo, mag: 7.1, size: 8.5’. This is bright and easy to find comet; obvious even in 102mm refractor with XW 14mm (51x), gorgeous in Edge 9.25” with XW 20mm (118x). Looks like a large unresolved glob.

88 P/Howell – comet in Virgo, mag 10.5, size: 3.9’. Tougher to resolve; faint round spot in Edge 9.25” with XW 20mm (118x).

The rest of the evening was devoted to hunting galaxies in Ursa Minor. This area was tough going last dark cycle, but the sky looked much better tonight.

Ursa Minor galaxies (all with Edge 9.25”).

NGC 5452 – extremely faint oval with averted vision (AV), moving EP for detection. Pentax XW 10mm (235x).
NGC 5712 - extremely faint AV oval. Pentax XW 10mm (235x).
NGC 5819 – small narrow shape with AV. Pentax XW 20mm (118x), XW 14mm (168x).
NGC 5832 - faint oval with brighter central area. Pentax XW 20mm (118x).
NGC 5836 – narrow shape. Pentax XW 20mm (118x).
NGC 5912 and 5909 – two faint ovals next to each other. NGC 5912 is a bit brighter. Pentax XW 10mm (235x).
NGC 6011 – faint narrow shape next to star. Pentax XW 10mm (235x).
NGC 6048 – small wide oval with brighter core. Pentax XW 20mm (118x).

NGC 6068 – faint oval. Pentax XW 20mm (118x).
NGC 6068A – tiny narrow faint spec next to star. Pentax XW 10mm (235x).
NGC 6071 – faint small narrow oval. Pentax XW 14mm (168x).
NGC 6079 - faint oval. Pentax XW 20mm (118x).
NGC 6094 – faint wide oval with AV. Pentax XW 20mm (118x).
NGC 6251 – faint round disk. Pentax XW 20mm (118x), 14mm (168x) and 10mm (235x).
NGC 6252 – extremely faint spot with AV below NGC 6251, shaking EP for detection. Pentax XW 10mm (235x).
NGC 6324 – faint oval with AV. Pentax XW 14mm (168x).
NGC 6331 – extremely faint small spot with AV, shaking EP for detection. Pentax XW 10mm (235x).

The Ring Nebula
I had a few minutes before Moon comes out and decided to take my first look with Edge 9.25” at M57. Oh boy what a view! Gorgeous, large and bright, with ton of details. However, there was no colors other than overall greenish tint. In the past I have seen red to blue color transition with 8” SCT and was expecting the same if not better. I will revisit on other nights.

I watched moonrise at ~23:30 and went to the last leg of the evening – shootout between Celestron Edge 9.25” and Stellarvue 102ED on Jupiter.

Jupiter
Callisto shadow transit was in progress and the sharp black little circle was well defined in both scopes. GRS was visible to, but barely resolved. The seeing was below average – typical for this season, however at the moments of calmer air multiple belts on Jupiter were coming in focus. I have tried different EPs and filters in both scopes. The amount of resolved details was about the same in both scopes. I could push to higher power with 9.25” Edge/Pentax XW 10mm (203x, 1mm exit pupil), but the glare of Jupiter was more intense in it. Jupiter image was larger but softer and with less contrast. With SV102ED the best views were achieved with TV Delite 5mm (143x, 0.7mm exit pupil), Jupiter disk was smaller, but the belts looked sharper and contrastier.

On a good night in the past I was able to push my plain 8” SCT above 300x for some fantastic views of Jupiter. I am sure 9.25” Edge should do even better. However, on average night it seems that there is no advantage of pulling anything larger than 4” ED doublet.

7/11/20

On the second night of the week I have selected Draco as my hunting grounds.

Draco galaxies (all with 9.25” Edge).

NGC 2908 – faint oval with averted vision (AV). Pentax XW 20mm (118x).
NGC 4391 – small oval with stellar core. Pentax XW 14mm (168x).
NGC 4441 – faint elongated oval. Pentax XW 14mm (168x).
NGC 4545 – faint round disk with brighter central area. Pentax XW 20mm (118x).
NGC 4572 – small elongated oval. Pentax XW 20mm (118x).
NGC 4589 – bright small disk with round core. XW 20mm (118x).
NGC 4648 – small oval with stellar core. Pentax XW 20mm (118x).
NGC 4693 – extremely faint small spot, shaking EP for detection. Pentax XW 14mm (168x).

NGC 4749 – AV oval in Pentax XW 20mm (118x), not detected in XW 14mm (168x).
NGC 4857 – FAIL.
NGC 5667 – small narrow oval. Pentax XW 20mm (118x).
NGC 5777 – sharp edge-on. XW 14mm (168x).
NGC 5881 – small faint oval with AV. Pentax XW 20mm (118x).
NGC 5894 – faint narrow edge-on. Pentax XW 20mm (118x).
NGC 5963 – large relatively bright wide oval next to NGC 5965. Pentax XW 20mm (118x).
NGC 5987 – small narrow lens. Pentax XW 20mm (118x).

NGC 5989 – faint round disk. Pentax XW 14mm (168x).
NGC 6088 – very faint small spot, A and B not resolved. Pentax XW 14mm (168x).
NGC 6140 – wide oval. Pentax XW 20mm (118x).
NGC 6143 – faint spot with AV. Pentax XW 20mm (118x).
NGC 6182 – small faint oval. Pentax XW 20mm (118x).
NGC 6338 – faint oval. Pentax XW 20mm (118x).
NGC 6434 – faint narrow disk with AV next to star. Pentax XW 14mm (168x).
NGC6742 – PN - faint round disk, no filters. Pentax XW 14mm (168x).

Finished with the galaxies (and one PN) around midnight. Jupiter was beckoning but the seeing was poor and no transits in progress, so I decided to call it quits.

Lovely pair of nights!

I agree about the aperture and seeing issues. When I had my Edge 9.25 it needed better than average seeing for planetary detail to be any better than with smaller scopes.

Thanks nFA! Waiting for that magical night which would make the Edge justice.

That's a very good report.
You had a couple of very productive sessions.
Congratulations.

A wonderful pair of sessions Andrey!

Looking forward to the time when I can bring one of my "big" 150mm Newts to a darker sky site and just hit galaxy after galaxy with ease, similar to what you do on these Anza nights (but with your larger aperture scopes obviously). All 3 of my 150mm Newts have not seen action away from home (one hasn't even been given a "first light" yet!). In fact, I've brought a 5" to darker sky sites just twice in my observing history (?!).

I like your comparison of Jupiter between the two scopes. Sometimes I get those moments of great seeing with the 5" Newt but many times the views aren't much different than with a 70mm F/12.9 achro. Saw the shadow transit of Callisto as well, including the time when the moon was at the limb of Jupiter.

Good catch of the two comets as well! Looking forward to seeing Neowise soon - good to see a bright comet for a change (PanStarrs was virtually invisible from my LP skies, even with 6" scopes).

You rebel - looking at different comets than the main attraction! :lol:

Looks like a couple of great nights - glad you were able to share. I too liked the Jupiter comparison between the scopes.

Thanks Terry! With my skyline I have a better chance to catch Neowise in the evening and the window is coming. :)

Interesting - looks like it is moving East vs. the sun so it should be up later. I may have to give it a shot - if it's ever not red here again.

Comet Chasers has it listed as being high in the sky during twilight at the end of the month - hopefully it stays bright enough to actually find!

Very good observations!
Must have been great nights. In your case I would have done the same: " Neowise obscured?" Then another comet!"
You proved again that, given moderate to inferior seeing circumstances, the smaller aperture with moderate magnifications has an advantage above larger aperture on Jupiter. Thanks!

Great report Andrey. Glad that you could get out for two successful nights. Neowise is now rising in the sky after sunset and should make a good target.
