New image, NGC 55

All,

Another one from last Tuesday night. The galaxy NGC 55, with nice colours. The blue regions were so bright that they show even in the raw frames. A deeper image, getting down possibly to mag 18 with 40 mins total exposure. Lots of background galaxies visible in the full res image, maybe not so apparent in the reduce one.

or, if there is a problem with going direct to the image;

I'm simply flabbergasted. :o

Please consider volunteering your images for Singastrofest to help promote astronomy. And stress that these images were taken from Singapore!

Absolutely amazing work, Thiam Guan! Kudos!

i think it's taken from east malaysia.

Most of Tg's pics are taken from Miri, but am I right to say that the recent shots were taken in Singapore?

Hi,

i think it's taken from east malaysia.

I think it is taken in Singapore, because he is in Singapore and he use a LPR filter...

Do remember to inform us when you are imaging again... will like to learn from you.

Have a nice day.

Thanks all, for kind remarks

I'm travelling at the moment, so cannot check in as often as I would have liked. Indeed pics were taken from Singapore. The LPR filter is almost essential, I think, as is the mod to increase sensitivity.

please excuse a newbie question...
how do you attach the lpr filter when taking astro prime focus photo with a dslr?

Hi Kong,

The filter I use has fits to the rear cell of the SCT, ie 2" SCT thread. I also stack the LPR and the x.63 focal reducer which has the same set of threads. The SCT-T adaptor then attaches the camera.

But I am curious how others have attached eg H-alpha filters in cases where they don't make them with SCT threads...
