Discussion Overview

The discussion revolves around viewing and photographing a planetary lineup, specifically Jupiter, Venus, Mars, and Saturn, as well as upcoming lunar eclipse events. Participants share their experiences, tips for astrophotography, and concerns about weather conditions affecting visibility.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants mention the visibility of the planetary lineup in the pre-dawn sky without the need for telescopes.
  • There are inquiries about effective techniques for photographing celestial objects, particularly using cellphones and digital cameras.
  • One participant suggests that a digital camera on a tracking mount or a tripod can improve astrophotography results, while others discuss the use of single exposures versus stacking multiple images.
  • Participants share their locations and how that affects their viewing experience, noting differences between the Southern and Northern hemispheres.
  • There is a mention of specific dates for close conjunctions of planets, with some participants expressing curiosity about capturing these events.
  • One participant expresses concern about missing the lunar eclipse due to being on a cruise ship, while another offers a light-hearted comment about the situation.

Areas of Agreement / Disagreement

Participants generally agree on the visibility of the planetary lineup and the challenges of photographing it. However, there are varying opinions on the best methods for capturing images and differing experiences based on geographic location. The discussion about the lunar eclipse remains unresolved as one participant will miss it due to travel plans.

Contextual Notes

Limitations include the dependence on weather conditions for visibility and the varying capabilities of photographic equipment among participants. There are also unresolved questions about the best practices for astrophotography.

Who May Find This Useful

Astronomy enthusiasts, amateur photographers interested in astrophotography, and those planning to observe celestial events may find this discussion relevant.

TL;DR
Jupiter, Venus, Mars, Saturn in the pre-dawn sky.
Looking East this morning about 5:15 am. No telescope needed. But the pic is not actual - it is from Stellarium.

Nice! I'll have to take a look tomorrow morning if the clouds clear!
 
Does anyone have any 'tips' on photographing something like this ? I tried my cellphone but it is hopeless - at least with the camera app. What sort of capability would you need on a phone to take a reasonable pic of objects in the night sky ? Or using a digital camera ?
 
Best bet is a digital camera like a DSLR on a tracking mount. But a tripod will do if your exposures are short. In astrophotography we usually take many pictures, called sub-exposures (subs), and then digitally stack them together to get rid of noise and make the final image look good. But if you don't have that capability you could probably get a decent image with a single exposure.

Where are you located ? Might not be the same view as from here (Johannesburg). More or less the same in Brisbane (Aus) but will be different in the Northern hemisphere.

I'm up in the United States. Didn't wake up early enough this morning to see it.
 
London view: about 6:30pm. I would guess you wouldn't see much because of the rising sun.

Summary:: Jupiter, Venus, Mars, Saturn in the pre-dawn sky.

2 weeks from the above, the planetary line-up is still clearly visible in Southern hemisphere skies just before dawn. Venus and Jupiter have moved closer together and - with the crescent Moon - form a neat right-angled triangle if joined:

I chanced my arm with this very basic cellphone pic. Point and click only - not even a tripod - but Venus and the Moon are clear enough (if a bit blurred) and you can even pick up Jupiter as a dim dot in the lower left corner. Usually when I try something like this the camera won't even focus on the astro-objects so I think I was lucky with a very clear highveld morning sky. Obviously I have cropped out most of the pic which originally covered a much larger area of the sky.

I'm sure there are better equipped enthusiasts out there - close conjunction of Venus and Jupiter worth recording perhaps ?

27th April to 5th May 2022. "Photo bombed" by the Moon on 27/04!

This has some interesting events throughout the month of May. I'm curious if @Drakkith will have a chance (and cooperative weather) to do some imaging on the Lunar eclipse coming up.

Unfortunately not. I'll be on a cruise ship in the Caribbean during the eclipse! :palm::palm::palm:
Edit: Just double checked. Turns out we'll be getting back to shore the night of the eclipse. So I won't have any equipment with me.

I've seen a lot worse excuses for missing an eclipse, enjoy the cruise! :cool:
