need learning aids for astrophoto
|
fastqx .
i'm an old guy who, after 25 years absence, (now at N 59.5 degrees) wants to watch the sky again. can you help me find a book/course/tutorial that would update me on modern amateur astrophotography? i am building a new dome, and have an old meade 12" lx200. electronics are eff-ed, but ota is just fine. i'm looking for a solid equatorial mount and the requisite "go-to" and tracking software.

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, there is a choice you will have to make up front on cameras. Either one shot color like the ZWO ASI294MC Pro or monochrome with red, green and blue filters like the ASI1600MM. These are the only two I have used personally and they both have pros and cons. For the mount, I would go with the 1100GTO. Mach2 is over a year wait if you get on the list now. I have a 10" truss RC and it's a little bit much for the Mach1 as well as an 11" RASA. I ran these on the Mach1 and it did ok but I could tell they would be better suited to the 1100. You call also get absolute encoders on the 1100 but I have never felt like I needed to use them. This subject could get controversial. Hopefully that helps some.

As a rookie I found Trevor Jones of Canada own Astrobackyard to be a great source of grounded reason. His transition from DSLR to CCD to CMOS is well chronicled in his videos. Might be too simplistic for you but it was a great start for me after much reading.

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. cytan

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. -- Mike Mike Dodd Louisa County, Virginia USA http://astronomy.mdodd.com |

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.

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

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, scopes, cameras as well as associated support equipment and software that amatures, and some pros only dreamed about 25 years ago. You need to figure out what kind of astrophotography you want to do and what would work best for your location as well as what you feel you are capable of. Your 12" Meade is a large heavy long focal length scope which could be difficult to master as the basis of a starting astrophoto rig. My suggestion would be to start with a good mount such as an AP, a reasonably good smaller to medium size short f/l scope such as a short focus refractor of say 100 mm aperture, possibly a DSLR(unmodified to start) or a one shot color cooled astro camera. I would keep things as simple as possible so you don't get overwhelmed and frustrated. This hobby can be quite taxing physically and mentally. As far as equipment goes, I would recommend you search sites like Canada-wide Astronomy Buy & Sell or Astromart for good used equipment. Can't go wrong with an Astro Physics mount new or good used. They are rock solid and simple to use with great support from the manufacture and from people on sites like this. With regards to software, there is a dizzying array of choices out there from expensive to freeware. Do your research on that as well. Keep in mind that you don't want to get overwhelmed with complicated software suites when you are just starting out. I would start with basic camera control software and try using the mounts hand control (AP has an excellent one) to select and track your targets. I would suggest you spend a good deal of time researching what's available for your budget(none of this is cheap especially in Canadian dollars!). Not sure if there is any local astro clubs near you. Atlin is pretty remote but try to find someone who can help you through the early stages. Just my Toonys worth! Good luck. Don Anderson

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

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 that is exactly how I started out. Of course the route that I
followed is not recommended, but the first thing I did (that is within a few days) after taking early retirement in 2012 was purchased a pre-owned 10" Meade LX200, at which point visual observing, not photography was my main ambition. However, it didn't take
long (about 3 months) for me to try attaching my Nikon camera, then a guide scope + guide camera, focal reducer, etc, etc.. For sure the LX200 mount had terrible tracking and PE, so yielded poor shape stars, but I was excited and pretty pleased to get some
reasonable DSO images, plus I learnt a lot on the way. For planetary and lunar imaging where accurate tracking is less of an issue the 10" Meade performed extremely well.
All of that said, it is FAR easier to get better results with a smaller refractor, even piggy backed on the Meade and of course I ended up parting with the LX200 in favour of a pre-owned Astro-Physics AP1200 mount, which is an absolute joy to use, but
these are rare items to find, certainly in the UK where I'm located.
Good luck and above all have fun.

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 - https://www.amazon.com/Astrophotography-Manual-Practical-Scientific-Approach/dp/1138055360/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1588684414&sr=8-5 2. The Deep Sky Imaging Primer, Second Edition by Charles Bracken - https://www.amazon.com/Deep-sky-Imaging-Primer-Second/dp/0999470906/ref=sr_1_7?crid=LW7SLOLA05HO&dchild=1&keywords=astrophotography+books&qid=1588684493&sprefix=astrophotography%2Caps%2C201&sr=8-7 Both are great book and either [or both] will get you a good start on the modern cameras, mounts, software and techniques. Good luck. -- Dean Jacobsen http://astrophoto.net/wp/ Image Gallery - http://astrophoto.net/wp/image-gallery/ Astrobin - https://www.astrobin.com/users/deanjacobsen/ |

I'll second Dean's recommendations, and I have both of these (and wish I had both when I started out).

There is no substitute to getting a good foundation. Terri |

Hi Dick, ...parting with the LX200 in favour of a pre-owned Astro-Physics AP1200I'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 9.25" SCT on a GEM, then another GEM, and finally a second-hand AP1200 that I still use. It is a wonderful mount, and imaging with it is MUCH easier than with any of the other mounts I've used. I use a separate guide scope and camera <http://astronomy.mdodd.com/observatory.html#Autoguiding> that typically yield guiding errors less than 1 arcsec with the AP1200. 2. IMO a DSLR is a good choice if you're just starting out. But I think buying a cooled CMOS astronomy camera is a better choice if your budget allows. Consider: A) A CMOS camera is powered from the USB (usually USB 3.0) cable, not from an internal battery that might not last through an imaging session. B) A cooled CMOS camera has lower noise than an uncooled DSLR. C) ZWO offers an off-axis guider (OAG) that mounts in between the OTA and the imaging camera. A small lightweight (and inexpensive) camera screws into this OAG. You can easily add autoguiding without needing a separate guide scope and camera. (I use a separate guider for specific reasons related to my imaging goals.) There's a lot to think about; I hope you're not overwhelmed. -- Mike Mike Dodd Louisa County, Virginia USA http://astronomy.mdodd.com |
