M42/43 New scope

Posted By Joe McBride
Hi, I got a new (to Me) 8" f/4 recently and have been getting aquainted with it. I haven't owned a newtonian scope in about 15 years so I had to relearn how to collimate. Anyway here is one of my first images with this telescope. I still need to tweek the collimation as all the stars are not round. This was taken from my back yard where there is tons of light pollution where M44 is barely visible. Taken through a 8"f4 with coma corrector with a modified canon XTi for 20sec X 28 with a few 30 sec thrown in for a total of 10 min and 44sec. I can't wait to get this thing tuned and head out for dark skies.

f/6.3 reducer in focus

Posted By Joe McBride
Hi, I am thinking about having a f/6.3 reducer modified to fit a 2" drawtube for a f/8 refractor. I know I will need to have some IN focus but does anybody know how much?

thanks

Using a st4 with a Meade LXD650 mount

Posted By Joe McBride
Hi, Has anyone ever auto guided with this mount. A friend of mine wants to maybe get a st4 to use with this mount if it is compatable. He needs a cable of some such to run the relays.\

Thanks

M42 last of season

Posted By Joe McBride
I finally got my new (to me) 8" f/4 out to the country under some very nice skies. Too bad it was -5F. It was so dry that my hand warmers stopped working. Here is my last of the season image of the m42/43 region. I went with 2 minutes subs because at f/4 the nebula washed out fast. Total time is just over 10 minutes.

Also the last for the season. 14 minutes with 5 subs through a 8"f/4 with a Canon XTi @ 800asa. I hope I didn't hurt my camera because it was so cold. Outside temp was -5F. As a precaution I kept the camera on all the time except to change batteries.

Laser collimator

Posted By Joe McBride
Hi all, I want to know what is the best laser collimator for under $100. I picked up a Newtonian telescope last fall and I see that I need one to help tweak the collimation. I see that Orion has one for $70 and Kendrick sells a couple for $200+. Any advice would be great.

Thanks
