Anyone does astro sketching?

Is anyone in our community into astro sketching? I've always had thoughts to try.

Re: 3D printing mounting rings

Depends on whether you actually want to do 3d printing as a hobby I guess... thought of buying too, but realised I just want to print occasional parts for astro, don't really want to spend time maintaining. I have been using 3dprintsingapore.com at toa payoh, user friendly website and good print qua...

Re: What power supply do you use to power your rig?

Looking around for LiFePO4 batteries preferably from local vendor for safety... probably don't need such a large capacity either. Any suggestions?

Re: How do Dobs/Newtonians fare in singapore light polluted skies

Making sure stray lights don't enter the scope should be the top priority. If that means you need to walk a little, a lighter scope might be better. Get a trolley too, if you have space at home you can leave the dob on it all ready to go.

Re: How do Dobs/Newtonians fare in singapore light polluted skies

I have a C8 and a 10 inch self-built dob, have briefly used an 8 inch dob for a while, also had the chance to compare the 10 inch side by side to a 12.5 inch in SG. I am a firm believer that "aperture is king" and would say the difference in aperture is as expected. Mainly small, noticeabl...

Re: Planetary Obession (latest: 2022 update)

Again, time to update this post. Only managed two images in 2022 due to multiple factors including my schedule and clear skies simply not aligning, a shift toward visual, and building of my dob. Venus - my first time imaging in invisible light. The colour palette brings out subtle cloud features. I ...

Re: Planetary Beginnings

Oh for deep sky astrophotography light pollution is a problem, but not as bad as for visual because it can be mitigated if you have long integration times or large aperture. And then of course there are filters which is a rabbit hole of itself. I think it really depends on your expectations. If you ...

Re: Planetary Beginnings

I feel it's not much use to find "dark" sites in sg because you can't really escape the light pollution. Anyway for planets, light makes absolutely no difference to the view because they are so bright. A good location for planetary will be somewhere open, away from tall buildings and other...

Re: Planetary Beginnings

Great job, it's really quite fantastic for a 6 inch scope. I think you've nailed most of the process, so it'll mainly be down to seeing. Observing location has a huge impact on seeing too.
