Emission Nebula Discovery in Puppis (journal article)

http://jeffjastro.com
Hi all:  I put together an article to have a document in the public domain (beyond my website) regarding the HII emission area/object I discovered near M47 (described in detail on my main site). The peer-reviewed article I wrote has since been published online:

The Boogie Man Nebula

http://jeffjastro.com
Hi all :) Here is a close look at "The Boogie Man" Nebula - LDN 1622  I used the big (TOA-130F) scope for this one, and was the first object that night. I imaged it when the EM200 mount was quite a ways past the meridian, which is impressive. Focus was not perfect as this started just as a test. The RGB from that night was not usable, so I used the RGB from the widefield / smaller scope from one year ago nearly to the day of this image.

TOA-130F (FS-60 for RGB), EM200, QSI540wsg
5x20min Ha, 3x10min L (bin1x1); 2x5min ea RGB (bin2x2);
10xdarks/flats/fdarks/bias.

3.7hrs of H-alpha - Cone Nebula region

http://jeffjastro.com
Hi all :) This is just a single channel/filter of data (H-alpha) - so, is monochrome - but, it is getting close to 4hrs of data in just this channel. I am still working the Lum (clear) and color (RGB) data, but this is from data collected over two nights on this object at the end of January:

Cone Nebula and surroundings (mono)
FS-60C, EM200, QSI540wsg, 11x20min (3.7 hrs) H-alpha only

I'll post again when the color is added, but a few objects such as this one I like in mono as it brings out different features.  :)
