I go about the selection of subjects a bit differently. First I determine the angular coverage of my lens/sensor combination . To do this you need to know the physical dimensions of your sensor. ...

Wow, Chris. That's an amazing amount of detail with "just"  71 mm and 1 hour integration. That Ha filter really must help. Thanks for sharing!

That would certainly be an option. Might also just get a Pentax 400 mm, f/5.6 lens (used). Even a small refractor would be another option.

Maybe it will work out OK. With my crop-sensor camera it will give a FOV of 6.7° x 4.5°. That might give the corona a large enough size on the sensor to be useful. It's what I'll be using along ...

One thing seems to be missing in the comments about "lucky imaging" being used for the solar eclipse - image size.  Jerry pointed out how lucky imaging is used to advantage with the tiny images of ...

I have used the Losmandy G-11 for about 8 years, with optical tubes between 25 and 35 lbs. They are spendy, particularly with the Gemini Go-To option. But that's well worth it for the ease of ...

Another possibility is that the green object is a "point meteor" - a meteor that is traveling directly toward the camera. The green color is consistent with the possibility.

Good job, TheLion! Looks like your tracking was very good. Nice capture of the Northern Coalsack as well as parts of Cygnus and Cepheus. You even got the Andromeda Galaxy along the bottom right ...

Yowza! What a sight that must have been. Was it traveling downward to bottom right of your photo? Definitely a very bright meteor (bolide?). Not an Iridium flare since those have a much more ...

Those are beautiful images, Chris. The detail is amazing. Did you use your 72mm refractor? Quite nice result. A few years ago I did a single frame of the same area using a DGM Optics NPB (Narrow ...

My climate is a bit different here in southwest Oregon. In August watching the Perseid meteor shower I was laying back in a lounge chair. For about 4 hours not generating much heat by any ...

You might consider some other items: (1) Memory card with adequate space (2) Camera battery charged, extra battery (3) Dew prevention ...

I'll have to look into that lens, particularly since it has been tested by an astrophotographer. I do have a Sigma 19mm, but it's only f/2.8. The 24mm f/1.4 is a nice fast  wide angle that should ...

Excellent image, Chris. It took me a while to recognize the Omega or Swan figure since you also captured so much of the faint nebulosity surrounding the bright parts. But well-done!

Roger, that has to be one of the finest deep-sky/meteor photos I've ever seen. Your interpretation of what was happening adds a lot to it. I've set this as one of my desktop backgrounds. Thanks ...

Nice capture, Jack. I've been watching how fast Mars has been moving relative to Saturn, Antares and Delta Scorpio. You've gotten all 4 of these in your image. Not too long ago Mars was located ...

Thanks, OllieN - I've got the information adjusted.

Thanks, OllieN for your contribution to our survey. I've entered your information into our database as shown below. Since the requested information has changed a bit as time went by, the numbers ...

Great! What a project you have undertaken. That will surely be a fantastic composite when you get it all processed.

That's great, Wade. Thanks for being willing to add to the survey. I've entered some rough, preliminary numbers in the database - splitting the totals, putting 1/2 on each camera. When you get ...
