Faint LMC nebula

[glenc]

Last night I saw a faint large nebula in the LMC. It is 48' east of NGC 2032 in pa 111.
Its name is H70 or SL673 or BSDL 2885 and it is at coordinates (J2000): RA: 05 43 14.9 Dec: -67 49 07
In the 12" using a UHC filter it is very faint but certain and about 12' diam.

Hi Glen,
Congratulations, Henize 70 is a very faint object (mag14?). I seem to recall seeing it through Gregg Thompsons 18inch many years ago from west of Warwick. I think it is believed to be a supernova remnant that was first noted by Karl Henize in a catalogue of LMC nebula in 1956. I have seen other catalogue numbers N70 and LH120 for this object? There is a lovely plate of this object (63) in The ESO book Exploring the Southern Sky - which in my opinion along with Hartungs (both volumes) are still 2 of the very best books ever produced for Southern amateur astronomers to hunt down some faint fuzzies.

Hi All
N70 is a difficult object and my hat is off to you glen for catching it in a 12" scope. that is a difficult observation. The nebula is more like the Rossette Neb than a supernova remnant.
Well done
Andrew

Thats good going Glen as I know how dim that object is. Below is a crop of it from this image of mine 4MB.

Can you recommend a good set of charts or map of the LMC and SMC. i would like to know what the name of the O3 PN? is below as well. I am in the process of doing a large very deep mosaic of both the LMC and SMC and would like to know more of what I am imaging.

Here is a start of the deep LMC 3.0MB

Thanks in advance. Bert

I observed H70 last night in the 16" with 13mm Nagler mag x140.
The cluster was quite easy to see with just the barest hint of nebulosity.
With an O111 filter an amorphous glow was seen.
A good catch Glen:astron: I look forward to your observation challenges:thumbsup:

Here is an O3 version of this area. It is more what like you would see visually as the human visual system sensitivity peaks at about this wavelength.

I would like to try and spot this visually myself. Here it is with my modded camera and 10 inch scope.

An easy way to find this is to go 78' north of the Tarantula neb in pa 19d.

Bert, do you have the Herald-Bobroff Atlas? It covers the LMC & SMC well.

Another possibility is Mati Morel http://www.assa.org.au/sig/variables/morel.asp
Here is a list of 6182 LMC objects.

The object in your last image (cr2) is NGC 2020.
Your large images of the LMC are great.

[hector]

I would recommend the Mati Morel charts if you want to observe the LMC or SMC. If you can find them the Smithsonian relased the Atlas of the Large and Small Magellanic clouds in the 70's. the SMC is still available but the LMC is out of print. You do occasionally see copies available. I can recommend them as I have a copy of each.

This is a very useful thread for a chap who frequently trawls through the clouds. I reckon its time I invested in the Mati Morel charts. Much appreciated gentlemen!

Thanks Glen, this will certainly keep a chap occupied for a while.
