MarkS Posted January 30, 2015 Report Share Posted January 30, 2015 (edited) NGC 2736 is part of the Vela supernova remnant. It is quite faint, and in RGB I found that the star field dominated the image even after my attempts at deconvolution. So this image is shot with 5nm Ha and OIII filters. ASA10N in f/3.6 configuration; STT8300M; DDM60. Total exposure time was 5hr 20min - half with each filter. Subframes were 10min each, and the maximum signal from the brightest part of the nebula was only 1500ADU - I clearly need more data! So I suppose it's a work in progress. Here is the result for the data so far. All processing in Pixinsight; preparation for the web image in Photoshop Mark Edited January 30, 2015 by MarkS Link to comment Share on other sites More sharing options...
