M51 and SN2011dh

[Yoddha]

Hello,

Here is my first image on M51 Decided that a supernova in it is a good reason finally to spend some time on this target.

The location is 1730m above the sea level on the territory of the Bulgarian national observatory. We had an astro party there this weekend. The weather was little bit above the average according to the astronomers there, but for us it was just great

The image parameters are 1h 50min - 11x10min at ISO800, 4 darks, 20 bias-es, modified and cooled 1000D, sensor temperature -0.5C, ambient ~9C, WO 110ZS, APT 1.53, DSS, PS

Very nice!

If only my eyes could see it like this through a scope

Clear skies,

Thanks for sharing this pair Paul! I wish I had a pre-nova image... Will have to wait for post-nova one

[mdstuart]

Thats it!

[Yoddha]

Here is a rework of the same data It will be great to hear your comments!

Very nice, the colours are looking much better. I notice you say you only used 4 darks, have you tried stacking without them (they will add lot of noise) not that I think you need to - great image!

[Yoddha]

Thanks Lewis!

I didn't try to stack without darks, but sounds like interesting idea. Darks are killing me at these exposure times - 10min per frame is a lot when you have to pack and drive Have to try if will be able to get in home close temperature with the cooling...

You can see this sn now with 20 x 80 bins with averted vision!

I made it out last night after giving my eyes 45 minutes to adjust.

Hi Mark,

20x80 I suppose that it requires serious observing experience!

It is interesting if the brightness changed since the discovery?

[Pete Presland]

very nice well done

[mdstuart]

I would like someone else to try with 80mm bins tonight to see if I really could see it. I logged stars down to mag 11.2 but the sn is around 12.1 so perhaps I was kidding myself..so go on give it a go!

Here we have clouds since last Thursday

Thanks Bunnydog1!

Great image. Here's my attempt from June 23rd. I used an Atik 16HR in combination with a William Optics 80mm f/6 triplet apo. The total exposure time was 11x3 minutes.

Thanks Peter! Your image is also great!

[cloudbuster]

that is a superb effort ivo!

[Yoddha]

Thanks Cloudbuster!

It is little bit immodest to write it, but I'm very happy that a re-processing of this image that I made few months ago is selected for AAPOD today

Gret image tried this. Few weeks go yours came out great

Thanks pat

Nice image - particularly good for a first attempt - well done

[Yoddha]

Thanks Gina! I was surprised that was selected for AAPOD
