I stargazed last night but didn't observe a lot of things.

Nova Cassiopeiae 2021 is still there and its brightness seems to not have changed.

Objects that I observed: Double cluster, M10, M11, M53, Stock 2
I also saw Saturn and Titan (very low in the sky)

[Toliman]

Txantsan!

Yeah, Nova Cassiopeiae 2021 is still same bright, I observed it too at previous nights.

[Vawmataw]

Since you work for an observatory, you should collect data about this star. hrh

[Toliman]

Since you work for an observatory, you should collect data about this star. hrh

And I actually doing that. This nova is one of our main targets right now.

[Vawmataw]

Txantsan! Is the distance to this star measurable?

[Toliman]

Yeah, it's possible to measure approx. distance of novae, seems that (from current data of brightness) this star should be certainly closer than 30000 ly.

[Vawmataw]

Interesting, that's really far!

I have to admit it's my first nova ever

[Toliman]

Interesting, that's really far!

Yeah, absolute magnitude of novae is big so we can see even very far novae.

I have to admit it's my first nova ever

Nice, congratulations!

[Vawmataw]

Time to list what I observed tonight

M3, M6, M7, M10, M11, M12, M53, M57, M94
NGC 457, NGC 869, NGC 884, IC 4665, IC 4756, Stock 2
Barnard's Star, Vesta, Nova Cas 2021, Saturn, Moon

[Toliman]

Good image
If you can observe M6 and M7 with their low declination, didn't try observe also M8 Lagoon Nebula? It's quite bright, despite quite low declination.

[Vawmataw]

No I didn't, probably later this summer because if I remember correctly it's only a small region that is visible and the current declination doesn't help at all.

[Toliman]

I would say that M8 should be now observable for you (if sky conditions will be good, of course), if you can see M6 and M7 now.

[Toliman]

[Vawmataw]

I observed Nova Cas 2021 and it seems like it has dimmed recently. I remember to have seen it as bright as HIP 115691, now it's almost as faint as HIP 115661. But that just might be me.

I didn't observe a lot of things, especially since there is strong moonlight. Of course I observed the Moon, but also Jupiter, Saturn, Bessel's star, NGC 869/884, M3, M5, M15, M31 and IC 4665

[Toliman]

Nice that you could observe something. Good image!

Yeah, Nova Cas 2021 is already less brigh.

[Vawmataw]

The sky was very cloudy tonight so I only saw the Moon and observed Cor Caroli and Alcor/Mizar. Now it's time for quite a cloudy/rainy weekend.

As you can see, the Moon is hazy.

[Toliman]

Good that you could observe at least something, we had storms and super heavy rain hrh

[Vawmataw]

Keftxo hrh

[Toliman]

At least we could see some spectacular lightnings hrh

Luckily sky should be clear again in few days.

[Vawmataw]

I've observed several objects tonight:

M5, M8, M10, M11, M12, M13, M15, M21, M24, M25, M31, M32, M39, M53, M57
NGC 457, NGC 869, NGC 864, NGC 6633, NGC 6871, Biurakan 1, Biurakan 2, Stock 2, IC 4665, IC 4756

Saturn, Venus, Nova Cassiopeiae 2021

Spoiler: Regarding Nova Cassiopeiae

I was watching earlier tonight the lightcurve of Nova Cas 2021 on the website of the AAVSO, and it seems like its magnitude rose to 6.7 and dropped back to 7.7 in the last 7 days.

This nova is very interesting, especially since it doesn't seem to fade out.
