Gallery / Keyhole Nebula from Chile
« on: 2019 April 16 18:04:10 »
Dear group, after a long time without posting here, I would like to share with you my last image obtained from my remote observatory. This time is for the classic Keyhole nebula, aka NGC 3372 in Carina constallation.

Even though there are tons of images of this beautiful object, I wanted to incorporate data from all the filters that I have. So the "natural" color is a blend of Ha, OII, SII and LRGB. Please find it at the "NEW" corner on my site :

Details on acquisition data and equipment :

Further more, I wanted to blend in the classical "Hubble palette". Not my speciality, but here we go:

Best regards,

Hello to all, from this link you can review my  homework of january from my remote instalation in Chile.

This time, the objects were:

    NGC 2736 : Pencil nebula or Herschel´s Ray
    GUM 46 : stellar nursery, relatively unknown
    Sandqvist 111 : dense dark nebula

I personally have not been very prone to narrow band filters, a little for laziness and a bit for not mastering the techniques for this particular type of filters. Now I think that those makes a huge difference. I suppose that this was already obvious to many of you, but I still had not experienced it at first hand  ^-^

Hope you like it.

All the best,

Dear  group, here I'm again with some new images from my new remote observatory.This will be my astroimaging home from now.

The site is located in Rio Hurtado, 1.600 masl. Seeing is expected to be 1 arcsec or so.,-70.7630512,15z/data=!4m5!3m4!1s0x0:0x8477c0b93afee859!8m2!3d-30.4725411!4d-70.7630512

So far, everything is working as expected with observation tasks programmed for each night.

The equipment installed there consist in OOUK AG12 newtonian astrograph, STL11K camera all mounted on Astro-Physics 1100 GTO GEM

Here you can see the instalation of the ROR :

And a drone overview of the hill :

Regarding the new images obtained so far :

1) First Light and the classics :

    Helix PN in Aquarius

    Silver dollar galaxy in Sculptor :

    Running Man Nebula in Orion :

    Full resolution crop :

2) Overlooked objects.

    Dorado Group in Doradus :

    MBM 47 in Aquarius

This is an interesting region of dust consisting of multiple interlocking ribbons of dust.

I'm working in a 2x2 mosaic of this region, but this will take a little more time.

Hope you like it.

Best regards,

Hi Group, enclosed you will find my work from the last new moon.

From Hacienda Los Andes, a nice place very close to Cerro Tololo International Observatory, I managed to expose two L:R:G:B series in order to compose a two frame mosaic.

Almost 15 hours of exposition and a similar time processing (ufff), so here is the result :

Hope you like it.
