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 choice.  Mono is "better" but much more complicated

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 basics: mount, camera, guiding etc.  The equipment section is probably a little out of date, but the fundamentals discussed in each section are still valid.  It provides a good overview of the whole process.  

I started out with a non-Astro-Physics mount but later moved to an AP1100.  Once I moved the the AP1100 I found that I was no longer fiddling with the mount because it just blends into the background.  Once your ready to actually start trying to image, I would recommend that you start with a 90-127mm refractor.   If you jump right into a long focal length scope you could spend a lot of time chasing your tail while you're trying to learn the basics.  Just my 2 cents.

Ray, I did an experiment to understand the source of issue. When I run APCC and nothing else, including not
having the ASCOM V2 I immediately get the -15.04056 vs the 4.48 in Tracking Correction. I don’t know of where
I could introduce an offset. Open to suggestions of the source and how to resolve.

Dick, get ready for the deluge of advice! LOL! This is THE list for getting help with premium gear. 

I'm pretty certain that an AP1100GTO would be more than adequate for the 12" LX200 OTA. You can get on the list for the Mach2 which I think would be awesome but not sure the wait time for those. Karen or Marj will know.

As for cameras ... if you look in this list's archives there was a very recent lively discussion about the move away from ccd to cmos and which cameras people are favouring.

As for books: you can't go wrong with the classics like Terry Dickenson's Backyard Astronomers Guide but newer resources might be more useful when it comes to gear. 

Camera choice will come down to what you want to photograph. You going to go after planets? One camera. Deep sky? A different camera.

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 for it.

I used an ST-8 CCD camera with LRGB and narrowband filters for about five years, and got some decent images processing with CCDStack and Photoshop.

The one-shot color camera is MUCH better! For one thing, read noise is very low. For another, getting a color image without filters is a big time-saver. I wouldn't go back, no way, no how.

I also have Ha and Oiii filters for when I want to image in moonlight. I combine these subs with full-color subs taken when it's dark.

Processing has also changed. Now, a program named PixInsight is the go-to choice, because it does EVERYTHING you could wish for. It has a learning curve, but there are books and tutorials.

Finally, a CMOS camera is suitable for electronics enhanced astronomy (EAA), where you can build a real-time image on a computer screen instead of looking through an eyepiece using software like SharpCap or ZWO's ASICap (I think is the name). This is really nice when friends or relatives want to "look through the telescope." EAA shows you more detail and color than you could ever see through an eyepiece.

I hope this helps.

Re: need learning aids for astrophoto

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 flop which means guiding should be done with an off-axis guider.
  
   I'd consider a nice f/6 100 mm to 130 mm refractor. AP sells top of the line refractors -- but getting one new will require a long wait.

  IMO, I'd really recommend buying cheaper equipment to see whether you like astrophotography first before sinking in more than $10k to $20k and then discovering you don't really like it.

Since we have exhausted the old Mach1 list from late 2018/early 2019, the second run of Mach2s will be offered beginning with folks who signed up in April 2019.  With the Illinois stay-at-home order recently extended we do not anticipate having our production staff back until the end of May at the earliest.  This makes it very difficult to estimate delivery dates for these mounts, which is why we have not yet notified anyone on the list.  We are hopeful to begin notification late this month with delivery starting in late Summer 2020.  However, this may all change based on Illinois law.  Thank you all for your patience.

The APCC tracking rate does not match the RA rate on the bottom (see screenshot below).

 

Something may have set an offset rate close to 1x sidereal in the ASCOM driver, which shows as a negative RA rate in arc-sec/secs in APCC status. Are you connected to some application via the ASCOM driver that might be setting a custom offset rate set in the ASCOM driver? (or did you set a rate there?)

Yes, one can certainly get sucked down the guiding perfection black hole.  As Brian has said, how do your stars look?  Are you happy with the stacked images?

However, as Roland noted, there is some room for improvement that really doesn't take a lot of time.  Use PEM Pro to evaluate your native periodic error and then have the software create a new solution.  You will be amazed at the difference when you run the PE analysis again in PemPro with the new PE solution running.

Subject: Re: [ap-gto] PHD 2 Guiding "Good Enough"

I would be happy with your current guiding RMS but I image from the city. My RMS is usually around .5-.8 and that had been fine for any imaging I do.

Can you run PEC while guiding with PhD2? I've read conflicting information on this subject and never really asked. I've always left it turned off since my stars are good. 



Thanks,
Charles

Yes, one can certainly get sucked down the guiding perfection black hole.  As Brian has said, how do your stars look?  Are you happy with the stacked images?

However, as Roland noted, there is some room for improvement that really doesn't take a lot of time.  Use PEM Pro to evaluate your native periodic error and then have the software create a new solution.  You will be amazed at the difference when you run the PE analysis again in PemPro with the new PE solution running.

OK, after pulling the imaging computer out and looking at the PHD2 settings I see that under the Algorithms/Mount Guide Algorithms/Right Ascension settings I am not using Predictive PEC.
