Don, Thanks for pointing out my error, I should have read the original post. Yes, a 12" will make the difficulties that I experienced with my 10" Meade all the more challenging, but I believe that it

I looked at his original post. His scope is a 12" Meade. Don Anderson

Gerry, this is a very nice and practical experiment that is very illustrative, thank for the analysis, Tom -- TJF MOBILE

Drift rate is not dependent on whether you have encoders. The primary drift rate is dependent first and foremost on your polar alignment. This is especially true of Dec. The RA drift rate will be

Hello, On 2 May 2020, over a period of 4 hours I took 120 images, each 60s exposure and 60s interval with a 150mm refractor at 1093mm focal length, unguided with my AP1200GTO mount, periodic error

I'll weigh in again with a few more comments about equipment, not learning aidss. 1. I agree 100% with how wonderful the AP1200 is. I too started imaging with a 10" LX200, then quickly moved to a

+1 for Dean’s recs.. I read both of these before I went online for some visuals of how to put it in play. Still a pilgrim on a pilgrimage. Tom Fischer

I'll second Dean's recommendations, and I have both of these (and wish I had both when I started out). The forums are great for helping to solve issues but can be difficult to use as a guide for

Hi Dick, you asked for "learning aids" so here are a couple of recent books I would recommend: 1. The Astrophotography Manual by Chris Woodhouse -

Hi Dick, I tend to agree with most of the advice you've been getting, BUT I want to say that it is not so difficult to get images with a 10" Meade LX200 and a stock DSLR (mine was the Nikon D90) as

I agree with Cheng-Yang Tan - wow, starting imaging with the Meade 10" SCT would be extraordinarily challenging.

Hello Dick Welcome back to the astronomy/Astrophotography hobby! A lot has changed with the hobby in the past 25 years. There is a wide range of equipment available to the amature today ie. mounts,

I would not start AstroPhotography with a 3048mm FL scope. But buy a mount that can support it later, and an 80-100mm triplet refractor for now. Camera? A ZWO cooled one-shot color camera is a good

I found the following book very helpful when I was dipping my toe into Astrophotography: Getting Started: Long Exposure Astrophotography by Allan Hall. It is available on Amazon. It covers the

Check out the ebooks by Alan Dyer. Quite informative with great illustrations. Sent via the Samsung Galaxy Note9, an AT&T 5G Evolution capable smartphone

Dick.... If you're aiming for "pretty picture" astro images like me, give serious consideration to a ZWO or similar cooled CMOS camera. I use an ASI1600MC Pro, but the '294MC Pro also has a lot going

Trevor's YouTube channel is very good as well as: *Chuck's Astrophotography *Ray's Astrophotography *The Astro Imaging channel - goes back more than 5 years! Thanks, Charles Sent from mobile device.

Hi Dick, I'm not sure that an old 10" LX200 OTA is the correct scope to start with for astrophotography. Its focal length is too long for a beginner even with a focal reducer. It also has mirror
