me and my scopes

Posted By Andrew Culpepper

I'm waiting for the sun to set. These are my first scopes, not counting the 60mm Cresent brand refractor. The MN56 is about a year old and the Mirage 7 I bought new in December. They're both wonderful.

M44 & Sony DSC-W1

Posted By Andrew Culpepper

I just got the Sony 2.6x 'Apo' telephoto lens for this camera. Here's a picture at full optical and digital zoom (15.6x):

It's a 30 second exposure at IS0 400, resized and sharpened in Irfanview. The camera is riding on a 7" Mirage mounted on a GM-8.

fun smile

Just a quick poll.

My first telescope was/is an Intes Micro MN56, purchased one year ago. It now shares viewing duties with an STF Mirage 7, depending on conditions and targets.

MN56 and Astrophotography

Posted By Andrew Culpepper

Hi Ed,
I've not used the scope for prime focus photography but have read about the problems that you and Mike have mentioned. http://www.ClementFocuser.com makes a pricey focuser that is 1/2" shorter than the stock focuser and should solve the problem of lack of in travel. I've also read about someone replacing the secondary with a larger one but that seems to be defeating the main advantage of the mak-newt.

30xw

Posted By Andrew Culpepper

Hi Brian,
I have a 20xw and 30xw and love them for the ease of looking through them. To the question of what is a good low power exit pupil, it depends on you and your eyes. Being so close to the 34, I think the expense of a 30xw is not justified by exit pupil alone. If the Pentax is to be a replacement then go for it. You'll love it. I use mine as the low power eyepiece for my F6 mak-newt.
