You will not find anything about it apart from it was supposed to be funded with Dogecoin. Musk has talked up Dogecoin a few times so may be this tells some thing, calls himself the Dogefather. On Saturday Night Live Musk called it a hustle, and howled, “to the moon,” a catchphrase used by doge enthusiasts intent on getting the cryptocurrency to one dollar. Make of this what you will, this I found looking around financial sites btw.

High flying birds like geese may reflect light and appear like a satellite. Not saying it was a bird but it may explain a wobbly path and slow or speed up. Never seen a satellite do anything unexpected and have seen the usual flares, blinking and going into eclipse. I have seen large birds at vary heights when imaging and surprising how many fly at night.

Well done that is a keeper.

It is excepted amongst us radio amateurs that the best time for random meteors is from midnight to about midday. When I did meteorscatter I always tried to get skeds after midnight but you had to be quick to get in before the best slots were taken. I have no idea if the speed matters but we definitely got more meteors in the hours just before and after sunrise.

Nagler 31 if anyone’s looking …

We did not protest when Mr Brown dropped it to 15% but it did not last of course. -
This one of my favourite objects as well and you have done it proud Peter.

I can assure you that us Brits know full well what VAT is and that it is in the price for consumers. If a business deals mainly with businesses then prices will not have VAT. If they deal with both businesses and consumers then the price will include VAT if not both prices should be displayed with equal prominence. At work we deal with mainly businesses, when we quote prices to a business it is assumed there is no VAT added although we always quote the price plus VAT. We do this because some unscrupulous firms try to catch you out by claiming the price you quoted is the lower price without VAT. The arguments I have had with some of these chancers, they are just trying it on or are ignorant of the law. -
Meteor Detection with RTL-SDR
wxsatuser replied to Stormchaser's topic in Radio Astronomy and Spectroscopy
Here is an image of the tropo signal with a satellite and just left of the tropo signal is a diverging signal, aircraft. -
Meteor Detection with RTL-SDR
wxsatuser replied to Stormchaser's topic in Radio Astronomy and Spectroscopy
I would say aircraft. I see these as well, often they appear along side the tropo signal that I receive direct off the GRAVES side lobes. Normally they run parallel and then diverge off the main signal. -
There are very few zoom lenses that can do better than that. Just like scopes we need to spend an arm and leg to get a good one. What is the zoom lens btw

Darks or Bias or both, dslr vs other.
wxsatuser replied to Malpi12's topic in Getting Started With Imaging
Modern cameras have on sensor dark current suppression. The 450D does'nt have it. -
If your doing short exposures, longer exposures may help, expose so the camera histogram peak is at least 25% from the left.

Cannot help with the filter but it may cause a reflection, may be some one else will comment on that. Re diffraction spikes. As you stop down they become more noticeable. An even number of of blades gives the same amount of spikes, 4 blades 4 spikes. An odd number of blades produces double the amount , 9 blades 18 spikes. You either love or hate spikes, me I don't care, it's something we have to expect if we use camera lenses.

Can I just add, although your sort of correct there are two autofocus systems in Canon cameras. The sensor autofocus only works in Liveview mode or in mirrorless cameras, I believe the whole sensor is used in dual pixel AF. In view finder mode there is a dedicated autofocus chip, I would assume that one wouldn't use Liveview in AP.

Very good image with the new kit. The halo seems odd, strange diffraction pattern across it, surprised that the Canon lens produced this. Strange things can happen with bright stars but may be the halo is from the rest of the image train, filter may be?

Never had an issue with banding on both my 60Da, 7dmk2 or 6d, noise yes but no banding.

where is back focus measured on my c8 edge
wxsatuser replied to iwols's topic in Getting Started With Imaging
I believe it is C Some way down this pdf, page 14 you will see the diagrams for the back focus. https://s3.amazonaws.com/celestron-site-support-files/support_files/edgehd_whitepaper_final.pdf -
A 747's maximum ceiling is 45000feet and modern SAM missiles go well above 52000feet anyway so it would'nt have mattered anyway. As to Mr Branson, when he does an orbit and reentry then that will be different and worth doing.

Most graphics programs should allow you to insert text on an image.

Using monochrome on DSLR vs dedicated astro mono camera

Which Canon DSLR should I buy?
wxsatuser replied to Yellow dwarf's topic in Getting Started With Imaging
If you can manage it go for a more modern version, the later the better. The later models have far better noise performance than the older models.
