Title: IC443 (The Jellyfish) in Ha
Post by: RobertM on Jan 06, 2016, 22:46:36
First for quite a while this, processing is a bit rusty as is dealing with bias, darks and flats...

25 x 20mins Ha filter guided using an OAG on the RH200.

Hope you like.

Yes I do intend to do OIII (weak signal) and SII (strong signal).

Very nice Robert - must be good to actually have some data to process. Out of interest when did you take this? Thks, John

I just remembered processing my Jellyfish and I remember there were some areas that could easily get burnt out if you were not careful with the processing, so this is nicely controlled.

Lovely detail, when did you start this? It must have taken a while capture 25 x20mins with the weather as it is.

Thanks for all the positive comments.  The data was captured over the nights of 31/12/2015 and 3/1/2016, most of it on the first night.

Excellent image Robert. Amazing detail and range of tones. The top of the 'body' has filaments reminiscent of a part of the Veil as shown in Decembre 'Astronomie' magazine (a Hubble jobby).
