Rosette from Riberac

[MarkS]

Rosette Nebula last Thursday night at Riberac.

30 x 5min exposures
H-alpha modified Canon EOS 350D on Skywatcher ED80 with WO MkII 0.8x reducer giving 480mm focal length.
No filters used (except for IR/UV filter).

Sky was very moisture laden which made the background level brighter and noisier than usual.

very nice,

was this the same night you had the condensation problem?

was this the same night you had the condensation problem?

Yes - but this image was taken with the uncooled Canon.

very nice Mark, glad you got something. Darks & flats as well?

[RobertM]

That's an excellent result Mark, especially as the conditions were really bad for most of that evening.

[The Thing]

Very nice, love the colours.

Thanks Fay. 

Yes, darks and flats as well, I always apply darks and flats.

I also shot a few more hours of M31 an a few more hours of M45 - I'll add the data onto my exisiting Andromeda and Pleiades images.  These are both medium term projects and I want to add even more at December UDSC.

Yep, along with a few more hours of M31 an a few more hours of M45 ...

Very nice Mark, must do that one day.

Fabulous image mark, one of my favourite subjects. 

What was the outcome of using your Cooled DSLR, as this worked OK without, but you seemed to have trouble icing up at other times?

i.e. Was the Peltier DSLR a success or otherwise?

[MarkS]

Was the Peltier DSLR a success or otherwise?

Too early to be 100% certain. 
It certainly reduces thermal noise to very low levels but it might need careful handling or further modifications to prevent dew/ice.

But I'm very hopeful ...

Mark, what capture program do you use for DSLR bulb?

[MarkS]

I forget. I'll have to check when I get home.  On my camera I control the shutter via the remote control jack (not the digital jack) because the 350D only allows 30sec exposures via the digital lead.
