Astrofest Shots in Infrared

[multiweb]

Rho Ophiuchus

Here's my first shot from astrofest 2018. QHY9/FSQ106N on G11/Lodestar OAG and Astronomik 742nm IR filter - 64x300s.

Little noisy. Seems that whatever you do you always need some more subs with Rho. :shrug:

Here's the standard blend IR IR/LUM LUM with one I baked earlier.

Horse Head

This one was only 23x300s collected over a few freezing mornings between 4:00am and 5:30am (sub zero cool) but for one of the mornings where my laptop froze and conspired against me. I had no end of troubles with USB and serial ports disconnecting so I called it quit after collecting only an extra 4 subs in one hour. It needs a lot more IR in the HH but the flame being brighter came up alright.

Enjoy the views. :thumbsup:

Wow! You've got the FSQ fairly singing in infrared. The stars right to the very corners are pinpoint.

It's fun to carefully compare with your 2017 image. The very blackest dust is still very black, but just inside the edges of the dust, there are lots of stars in near infrared that just aren't there in RGB.

Great to have the two images to compare.

Very best,
Mike

Thanks mate. :thumbsup: Yeah it's a very sharp scope. My only limitation now is guiding and keeping it in focus. Still working on both.

[petershah]

That's a superb shot Marc. Great to see images taken with IR....A nice clean looking image and the detail is just lovely...Tak sharp;)

[RickS]

A very interesting and new take on Rho, Marc. Well done :thumbsup:

[multiweb]

Thanks Peter. :thumbsup: Yes, attention to focus pays dividends with TAKs for sure. I'm looking into other filters and bandpass as well so I can image from home in the light pollution.



Thanks mate. :thumbsup: It worked well. Very happy with the data. Looking forward to your widefield montages.

Jut noticed a couple of fain fuzzies in my IR Horse head shot (http://www.astropic.net/astro/IC434_IR_IRL_L_FSQ106N_1to1.jpg). See if you can find them. :)

[Andy01]

A beautiful monochromatic take on Rho, and an unusual Blue Horsehead!
As Spock would say - Fascinating! :eyepop:

Great creative use of the IR - a technique well worthy of further pursuit.:):thumbsup:

[multiweb]

Thanks Sensei. :thumbsup: Did you get those filters yet?


Oh no... the kraken has been released! :eyepop: :lol:
Waiting with anticipation for your next palette experimentations :painting:

[strongmanmike]

Interesting work Marc, cool :thumbsup:

Mike

[Retrograde]

Great work Marc. An interesting and unusual take on some familiar objects.
The blue Horsehead looks very cool but might be confused with another object!

[ozstronomer]

Nice set of images, I have not seen those objects in IR before.

Looks Cool :thumbsup:

Thanks Mike. :thumbsup:


Thanks mate. :thumbsup: The HH has too much LUM in it still. It was freakin' cold in the morning at 4:00am. I'll bump up the IR from home. It needs loads more and will look very different I suspect. What other object do you mean? :question:


Thanks Geoff. :thumbsup: Yes, it gives me something else to do from home with my light polluted skies. I only took the IR filter at astrofest because the seeing predictions over the week were less than ideal and I started doing planetary the first two nights.

[Placidus]

You were unbelievably productive Marc.

The Ara IR-Lum image is especially pretty.

[h0ughy]

looks like someone had lots of fun.........

[multiweb]

Thanks mate. :thumbsup: Found some old LUM raw files so I'm reprocessing some of them in PixInsight. Rick aka Ricardo Padahuan did a two day tut at astrofest on it. I'm nearly fluent in spanish.


Sure did. :)

[peter_4059]

Cool IR shots Marc. NGC6188 looks completely different.

[multiweb]

Yeah most of the fronts are missing from that one. Only the very darkest dust remains.

[Stevec35]

Only just saw this thread. Great shots Marc. Certainly different to the way I do IR.

Cheers

Steve

[multiweb]

Thanks Steve. :thumbsup: Yeah I only use a planet IR filter so 742nm onwards and blend 50/50 with the LUM. I don't have narrowband IR filters like yours yet. I think dedicated IR bandpass to RGB works well for long FL like what you do to differentiate smaller scale structures. In wider field blocking larger chunks of the spectrum shows interesting results, some DSOs better than other. And it's great to isolate Sii or other stuff that there's not much of. The blue lagoon was an unexpected result. I reckon that could work well for other targets. :question:

Hello Marc,


Sorry, a bit late, I have not been on IIS for a while, but...amazing work!


You continue to push the boundaries.


I love the Eagle nebula photo.


Ross.
