NGC2835--Anybody heard of it?

This is a pretty little galaxy in Hydra. It's very faint, so really needs much more exposure than the 4 hours I've given it. Still, after looking at the raw images downloading it's turned out better than I thought it would. There are very few images of this one around. I only found one other on IIS.
Details:
Exposure: 1 hour each of R, G and B and 70 min L
Camera: FLI Proline 16803
Mount: AP900
Telescope: 12.5" PlaneWave CDK
Processed in PixInsight.

Still looking good at four hours Geoff. Its hard to image anything in Sydney at the moment :cloudy:

A very pretty little galaxy, Geoff, and a great result for 4 hours!

Yeah given my fettish (one of a few) with imaging galaxies in recent years I recon I have trolled just about every galaxy list :scared: looking for good targets and I do rememeber this one, funny always hard to decide which galaxy to image and one can not image'em all huh? :)...so it is good when others hit them like you have here and it's a great looking galaxy and nicely imaged as usual, looks kind of like a cross between the nearby NGC 2997 and NGC 6946 the fireworks galaxy :thumbsup:

The new camera looks to be doing a good job too

Very nice Geoff. A noticeable improvement in quality of the image, from the camera right? Good processing as well. Lovely stars and galaxy colour.

A winner.

Greg.

[Geoff45]

Thanks Rod



Thanks Rod and Rick

Thanks Mike. As you say it's a nice looking galaxy--more aperture would be good though. The camera works very well (so far).


Thanks Greg. I think the FLI is giving me better images for 2 main reasons--bigger pixels (9 microns vs 7.4) and, more importantly I can image at -30 all year round, whereas with the QSI I was often doing -10 on hot summer nights.

Great Image Geoff, I love the spiral arms, so distinct !
Now I was going to ask more about it (as I am a visual observer) but instead, here are the details from CDC & the Star Chart:

Thanks for the positive comment Ian and thanks for the details.

Very pretty field Geoff! :thumbsup: Full res version shows good resolution too so you've got that scope performing well. Your seeing must have been reasonably good too. Any idea what your FWHM was for your raw frames?

Don't get me started on Sydney weather! :mad2: The good news is when it's been clear the seeing has been pretty good here in Grose Vale.

Cheers, Marcus

[Geoff45]

Thanks for the positive comments Marcus. The FWHM for the raw frames was around the 2.5" mark. Decon on the luminance pushed that down to 1.7". I've occasionally got down to 2" at Wiruna, but not often.

Tiny galaxy with plenty of details. The whole field looks great too. Finely tuned scope. :thumbsup::thumbsup::thumbsup:

[strongmanmike]

Hey Geoff, forgot to mention too, no obvious sign of decon, well done :thumbsup:

Mike

[Geoff45]

Which means I did it correctly!

[Stevec35]

A very nice result Geoff!

Cheers

Steve

[Geoff45]

Thanks Marc. Yes, it's a great scope. Very pleased with it.


Thanks Steve.

[Placidus]

Exquisite!

The rendition of the stars is very suitable for the season.

[Geoff45]

Thanks Mike. Do you mean there's too much sparkle and colour?
Geoff

[Placidus]

Absolutely not too much sparkle and colour! I really really like it exactly as it is, straight up! Showing that some stars are bluer and therefore hotter, while others are more orange and therefore cooler, is completely legitimate scientifically, and the result is very pleasing.

A great looking galaxy photo Geoff.

Very sharp and I love the colours.

A new object for me as well.

Ross.

[Geoff45]

Thanks Ross. A new object for most of us i imagine.
