Hi,
I recently spent my Xmas money on an L-Enhance filter as I have seen amazing results with this filter.
I took it for a test run on the Y Cas Nebula last night (not the best night, but when is?)
I managed to get around 43 mins of time.
I normally shoot 1 min exposures with my 1000D modified camera but I thought I'd go for 90 seconds as the filter would reduce brightness? (any thoughts on exposure times here would be great)
The results were not as great as I was hoping for - see below.
O over stretched it just to see if I had captured the 'ghost'. He's there, but it turns out really grainy and not the nice subtle wispy nebula that I see from other folks.
So my questions are:
- is this a tricky nebula target?
- What exposure times should I run?
- Is 43 mins way too little for this (or any) target?
- any other advice???
Setup is:
Canon 1000D - modified
L-Enhance filter
Skywatcher 72ED Telescope
Skywatcher AzGTI mount (AZ mode at the moment until I can get polar alignment working with SharpCap)
Any thoughts, hints, tips greatly appreciated!
Thanks in advance!

Hi! So Ive found some pictures from an arxiv report in a database which I need for my project and converted them to fits files (The picture on the left). The one that was used in the arxiv report (picture on right) is a zoomed in picture of a galaxy in that picture, where its clearly visible. However when I try zooming in on the exakt coordinates of the galaxy in the fits image, its just plain black. I want the picture "raw", that's why I saved it as fits and not their pdf picture from report. Someone suggested first stretching the image for a more detailed image but some filters had to be used though... the only thing I can find on the tables of the images is that filter F160W was used. I have no idea how to move forward now, completely stuck. Would appreciate some help!
