hunting for rim nebula !!! Wascally webula!

#1

Post by yobbo89 »


so i came across a target in stellarium , it was just a name icon with no image. rim nebula and i clicked on it and it showed up in details as ngc 6188 ..

anyhow i tried rim nebula in frame and mosaic in sgp and didn't find anything. so i tried ngc 6188 and it only gave me a star field with no nebolisty in the framing image... , so thought i'll give it a try, behold dense nebolisty after a 10 min exposure but no rim nebula !, i stuck 2 hrs of data in the first framing attempt and i thought about completing it with sii,oiii but i was too keen to hunt this rim nebula, anyhow i frame mosaic the current object i'm imaging and added onto it, sgp plate solved my saved imaged data and it pulled up another framing image from astronomy.net this time it was ngc 6188 but with nebolisty detail !!..... the annoyance of being handed a dud image for framing then a much better one after ... but still no rim nebula, images show online that it is in this region !..

The sho image is from a user over at cn, attached for info on whereabouts rim nebula should be .

i've uploaded the two different frame images from sgp ..

it looks like i have to image another portion of the sky to the right next to panel 2 ..., it looks like it might be there !

Great image so far!

NGC 6188 also carries the designation RCW 108.
There are two links below, looks like you nailed it judging by the image in the ESA link.

https://www.google.com/url?sa=t&source= ... 7679072818

EDIT: Another great resource, RCW 108 is on page 101 in the link below.

In the catalog there are the exact coordinates for the Rim Nebula, so you should be able to get it well centered.

well, i found it ha!, now i'm stuck doing 6 panels .. i couldn't do a 2x3 grid and dealeat 2 of the already made panels in the framing .. i had to make a row of 3 then re make another sequence for the last panel . i plan to do 3.5 hrs per panel , so 21 hours worth, i don't think i'll have enough time to do a colour image,sky conditions are never reliable or have consecutive nights of good sky.

Nice!
That is a lot of time on target! Wishing you plenty of clear skies for it!
And the catalog can help you pick out future targets, the author claims most should be visible with long exposure imaging.

I observed NGC 6188, which I know as the Firebird Nebula and its associated cluster NGC 6193 a few times using my ED80 at a location just south of the equator. My best observation was in March of 2016. An extract from my notes is below:


NGC 6188 (Ara, diffuse nebula, size=20.0’x12.0’): During the session two nights ago, this object was difficult and elusive. Given how bad seeing had been this evening, I was hoping transparency had picked up just a little bit and that maybe this nebula complex would be a little easier to pin down. So I slowly moved south a little more than 1° from NGC 6200 until I located the bright cluster NGC 6193. Staying at 27x for the 3.2° TFOV, I moved my eye around in all directions from the cluster. As with the previous session I was getting a sense of very subtle haziness. I inserted the Ultra Block and the haziness picked up just a little more. I noted some haze particularly around the brighter stars in NGC 6193, and got a sense of a little more density to the north and to the west of the cluster. I then put in the O-III filter. This time the O-III did make a noticeable difference. Though its presence still remained subtle, it was more discernible in the O-III particularly to the north and west of the cluster. The view just gave an overall impression of looking through a thin haze of dusty air. You can see, but things seem ever so slightly unclear. So it would seem my guess about the transparency was correct, and it was most definitely was more visible this time. Though granted, in the 80mm it was still a diaphanous presence.
