Hi,

Using an online chart and my Pocket Sky Atlas, I was able to starhop from Sagitta and locate this "new star" right on the border of the constellation Delphinus. I waited in my zero gravity chair with my 12x36's for about an hour while high clouds drifted through the Aquila/Sagitta/Delphinus region but my patience was finally rewarded and it was a farly easy hop once I could see the complete starfield.

The nova appeared as a crisp bluish-white point source. About .7° to the SW was the planetary nebula NGC 6905. At this magnification and with the limited transparency and bright moonlight, the PN was hard to see at times and needed averted vision to relocate when it would wink out. I also had to struggle with heavy dew conditions and got the hair dryer out 3 or 4 times during the 2 hour session.

The sketch was done at the eyepiece with 2B and HB pencils and a sharp stump (for the PN).

Pretty cool to see this nova--an unimaginably massive explosion so far away but still visible to us. :cool:

Michael,

Beautifully captured in your sketch.
Always fun to track the changing brightness of a classic nova.

Frank :)

Thank you, Frank. It's pretty neat to get in on this nova right near the start. I might be able to get another look at it tonight before the weather drops out. It will be interesting to see if it continues to brighten so steeply.

Congratulation Michael, you succeed sketching this nova at the very begining.
Tonight I will try too. The suspence is : what will be the magnitude !

Nice sketch Michael! As bad as you thought your conditions were, mine were worse! Limiting mag in the scope at 85X was about 8.5, so I couldn't see any of the stars in your sketch except for the 8th mag star north of it. My FoV was very restricted compared to yours also at 0.8*. It didn't get any better at 127X either. I gave a quick look for NGC 6905, but not even a hint it was there.

It's interesting you saw it as cool white or bluish. From here it appeared yellow or gold to me. We had a layer of haze also, so that may have been part of it. Or maybe the difference in EPs? :shrug:

Anyway, I feel lucky to have seen it at all with the cloudy weather we've had here this summer. Hope it stays bright a while longer. I'd like to see it under better conditions.

Thanks, Michel and good luck to you tonight. I think it's still getting brighter. :cool:

Larry, glad you liked the sketch and thanks for sharing your experience. Your cloud cover sounds much thicker than mine. Don't know about the star color--I've read reports where some people describe it as yellowish and others describe it as blue-white or white. The view of 6905 definitely seems to suffer from poor transparency.

Very nice, Michael, especially under these conditions. Although I guess that for such a rare and spectacular event you're more motivated to do the extra mile. I'll have a go at it this evening. :D

Jef, Peter--thanks you! I agree, the nova is a motivator to get out and look. Veteran variable stargazers are saying this is the brightest nova in 40 years. :cool:

I was out this morning with the 12x36's (0530 8/17 UT) looking through fairly thick clouds at it. No chance to see it with the unaided eye--the only stars visible were the Summer Triangle--but through the binoculars I estimated it at 4.8m. That is a little brighter than yesterday but from reports it has peaked at ~4.5m and is losing brightness.

Good luck with your own nova observations. :)

Great sketch of this nova, I saw it last night through Frank 5817's scope at his outreach program , very cool to see this unusually bright new star, and great sketch.

Thanks, Tom. :)

T5--that's sounds like fun. It would be so great to stargaze with you and Frank. One day, maybe... :cool:

This is a good wide field view of Nova Delphinus and the surrounding area. I see I was correct in how I depicted the color of the nova, clearly it shone yellowish white to you as well. Nice work!

Thank you Michael,

I need to go buy some supplies, that night I did the sketch I used a #2 pencil and the rest was photoshop.

I just dug out some old art stuff I had, here is what I have.

Mars Lumograph 200HB 2.0mm/ Mars Carbon 200HB 2.0mm both cases are new. the 2 on the right are 05 and 07, not sure if they can be used.

Make me a list to get, I'm going to try and head to an Art store tomorrow. I got tons of paper and other supplies just need the good sizes on leads and brands. I want to try some Nebulae :D
