Discussion Overview

The discussion revolves around an astrophotography image of Messier 45 taken on October 6th, 2013. Participants share technical details about the equipment used, exposure settings, and processing techniques, as well as suggestions for improving the image quality through longer exposure times and guiding methods.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant shares an image of Messier 45 and receives positive feedback.
  • Another participant suggests that increasing exposure time could enhance the visibility of dust in the image.
  • A participant details their equipment setup, including an Astro-tech 6" Newtonian telescope and a Canon 550d camera, along with specific settings used for the image capture.
  • Some participants discuss the potential benefits of using an auto-guider camera for improved tracking and longer exposures.
  • One participant mentions difficulties with stacking images using Deep Sky Stacker (DSS) and expresses interest in purchasing AIP4Win for future processing.

Areas of Agreement / Disagreement

Participants generally agree on the benefits of longer exposure times for astrophotography, but there are differing opinions on the necessity of auto-guiding and the effectiveness of various software tools for image processing.

Contextual Notes

Some participants express uncertainty regarding the effectiveness of their current image stacking methods and the specific challenges they face with software tools.

very nice ^...equipment?
 
Nice! A little more exposure time should really bring out that dust.
 
Thank you...yes I forgot that. Astro-tech 6" newt, Canon 550d, tracked on a HEQ-5, used backyardEOS on laptop for cam control, 100 secs, ISO 1600, single raw image, processed in paint shop pro.
 
thanks Drak!

Oh wow. Yeah, you've only got about a minute and a half of exposure time. Get a good hour or so and you'll be amazed at the difference.
 
I have an SSAG auto-guider cam I bought used. I'm just waiting to buy the right smaller guide scope for it.

Then I can go to town :)

You don't need to autoguide, though it makes things easier. You can take multiple short exposures and stack them together.
 
Yes I understand that , but I have had trouble with dss , I actually shot five of these at 50 or 60 seconds. Then a coupleat a 100 secs.I may buy aip4win this winter
