Beautiful!

Nice. Is this done using narrowband filters? Mono or OSC?

Pretty clear after 11pm except areas within 20 deg of horizon. Small clouds floating by from time to time but this didn’t interfere with area of interest. I tried Galaxy imaging from 10pm - midnight, but that didn’t turn out well. High level scattered clouds and quarter moon nearby reduced the contr...

I’m using the Zwo Asi533mc pro and Asi585mc (non-pro version). So far, no dew problem. But I usually stop by around 1-2am, so maybe the air is not so humid yet.

This image was taken last night (17/18th May, from around midnight).

Skies were generally clear last night (17th May) from 9am till around 2am. There was a quarter moon around the Virgo-Bootes constellation though, which messed up my plan to image galaxies around the area

Thanks for the tip. Yeah, I think I also overstretched some areas like core of M51. I gotta learn how to properly use these image processing software first. Previously I just do visual and simple EAA with no post processing. Life was much simpler then :). But astrophotography can be addictive! (And ...

Images of M51 and M57 taken on Thursday 9 May 2024 through Williams Optics Megrez II 80mm. Unguided subs using Zwo Asi533MC Pro cooled at 0degC. Streaks on M51 image likely due to live stacking. I did not take darks or flats. M51: 60s x 50 live-stack, stretched using GIMP. Stacked100_M51_30.0s.jpg M...

It is quite intuitive to practicing imagers that Bortle class do vary over our small island. (Refer rifleman175's A Method of Determining the Bortle Class at my Observation Site), i do agree with rifleman's finding that "the light pollution at Senkang is around Bortle 7.0 at altitude of 55 deg...

Hi Bernard, Very nice images. I'd actually venture to guess that it's really Bortle 7 to 8 at you location rather than Bortle 9 from your images. I'd suggest that you start stacking more than 30 subs (1 hour at 30 s is 120 images, 3 hours is 360 images) and then process offline. Looking at your dat...
