Equipment you most regretted selling.....

Posted By Maurice Clark
Mine was a 5" f/5 Jagers refractor that I had owned for more than 10 years. I sold it to fund a 16" dob.

I was lucky. I sold it to a friend who later sold it on to another friend of mine. 5 years later I was able to buy it again. The advantage of living in an isolated state with few amateur astronomers!

I still have it and use it extensively for photography and wide-angle views.

Imaging and aperture

Posted By Maurice Clark
Hi John,

For imaging, f-ratio will determine how quickly extended objects such as galaxies and nebulae will be recorded. So, if you have say a 16" f/5 and an 8" f/5, they will record extended objects equally fast. However because the *actual* focal length of the 16" will be longer, it will have a smaller field of view but better resolution.

For point sources such as stars, the f-ratio makes no difference. Here aperture rules. The 16" will record fainter stars than the 8" for the same exposure.

hope this helps.

Nephilim -Part 1

Posted By Maurice Clark
Hi Brein,

Nice to see you back again. However in reading over what you have posted on this topic I cannot agree with the author of the book you are quoting from. To equate the "sons of God" with angels in Genesis and Job, is not in harmony with the rest of scripture. Nowhere else in the Bible is the "sons of God" used to refer to angels. It always refers to followers of God. For example, Jesus was only refered to as the son of God after he took on human form. Also, the Bible teaches that the Holy Spirit is given to those who follow God and that as a result they are given power to "become sons of God". Humans do not become angels. Therefore it is very clear that the Bible uses the term "sons of God" to refer to humans who follow God. It is incorrect Biblical exegises to make the Bible use a term to mean one thing in one place and something else in another. It also shows the danger of focusing on just one Bible passage instead of looking at all passages dealing with the topic.

All the best

What is going wrong?

Posted By Maurice Clark
Hi Al,

I suspect that your exposures were not long enough. From the combination you describe, I would say that you would need exposures of around 0.5 - 2 seconds.

Check the negatives and see if there is anything on them.

Cheers,

Maurice

DSO magnitudes-vs-Star magnitudes

Posted By Maurice Clark
Hi James,

The short answer to your question is, not really. The biggest problem is how spread out the DSO's light is. For example, galaxy 1 might be very small and faint, yet be visible in the telescope since its light is concentrated. However galaxy 2 that is very large might not be visible even though its total magnitude is greater than galaxy 1.

As a *very* rough guide, a smaller DSO will be easier to observe than a larger one of the same magnitude.

Of course, this does assume that the published magnitudes are usable for visual observing!!!

The only sure way to know is to try.

Cheers,

Maurice
