Have you considered photographing the quarter Moon? Shadows are very short on the full Moon, so little detail shows, whereas on crescent, quarter and gibbous, at the terminator, the shadows are long and the detail is crisp. Motion blur is commonly caused by a setup which is insufficiently rigid coupled with a shutter speed that is too long. As Mike says, open up the aperture and crank the ISO up, which will also allow you to use faster shutter speeds. I shot the Moon last night at ISO 800, f/9 and 1/250.

You could also try eyepiece projection if you don't have or want to by a barlow, although the barlow will make life easier.

Someone has already suggested Making Every Photon Count, so I'll add Astrophotography by Thierry Legault. It covers an awful lot and in good depth.

I have Astrophotography by Thierry Legault. I don't know if you would consider that the appropriate level, but he is an engineer and discusses things in quite some depth.

This illustrates my point nicely. I have been in business for more than 25 years and never work on the basis of undercutting the competition. I've seen far too many businesses go to the wall by failing to maintain margins. On the same principle, recessions serve a purpose by getting rid of poor businesses that do a great deal of damage to marketplace. If your business can survive a recession, it will come out the other side with greater potential for profits as much of the low-price competitors will have gone to the wall. Of course, if you can lower prices without lowering margins or profitability, through technological innovation, etc, then by all means do so.

Competing by undercutting prices is a potentially dangerous tactic which can start a price war that leads to no-one making money. This is Economics 101. The better thing to do, as a manufacturer, is to keep your prices slightly above the competition and focus on quality and benefits to the customer.

Hi Gina I don't know if you can help, but I want to run a Raspberry Pi for imaging with a ZWO ASI178MM camera and Daystar Solar Scout. However, I need to run with a monitor and keyboard as I intend to take the setup to Gran Canaria for the Mercury transit and will have no other computer with me. So, I have a couple of questions: Do you know if this will work with the new Raspberry Pi 4, as mine will not arrive until next month, now? I have some 3B+ Pies, if not. Do I need to do anything other than connect a monitor and keyboard to use this in normal mode, i.e. not headless? Basically, I need a complete stand-alone solution which will run from the car battery via USB 5 V converters and possibly a small inverter, which I would rather avoid, but might need for the monitor. Thanks.
