Is there a way to re-set the sliders to where they were, I moved them all to the left for the Select Image/Sun ? Thanks

Also correct, and 0 when the tube is horizontal.

From Twitter: Dr Heidi B. Hammel@hbhammel·20hThis diagram of NIRCam optics is complicated, but the take-away is that when the "Pupil Imaging Lens" is in the beam, we see the *mirror* in focus, rather than the *sky* in focus. This mode is used for only alignment and engineering, not for science.

Looks fine to me, apart from the lack of a counterweight.

I don't know if they are the same, but on the TS Optics RACI finder version (Which was also at about 45º to the tube), the eyepiece can be unscrewed and the support ring moved. Is yours like this? I know you said above that you unscrewed it, but I'm wondering which bit you unscrewed , or maybe the SW version is different.

Looks great! I did that on my ST 80 😀

Many thanks to @Pete Presland for the rapid delivery via Hermes of Sky-watcher 0.9 Coma Corrector.

Thanks, it will be interesting to to compare it to StarXTerminator

What mount is this? Those scales are usually only very approximate.

How close to the stones will I get? How close to the stones you can get during normal opening hours at Stonehenge During normal opening hours you cannot walk up to the stones themselves. The nearest you will get to the stones is about 10 yards, the monument being roped off by a low barrier, (see picture below). However it is possible to walk up to and among the stones at Stonehenge outside public opening hours. These are called Special Access visits. During these sessions of one hour duration, only 26 people are allowed onto Stonehenge, going beyond the barriers and walking amongst the stones. The fact that these Stonehenge Special Access visits are outside public opening hours mean that they are at dawn or evening. Given that Stonehenge is two hours' drive from London this obviously provides logistical issues in getting there. The Special Access Visits are also immensely popular, demand far outstrips supply and they are often sold out months in advance. We have dedicated pages for people independently wanting to partake in a Stonehenge Special Access Visit and also a page on scheduled Stonehenge Special Access Tours from London.

NASA TV NASA to Discuss Webb’s Arrival at Final Destination, Next Steps Scientists and engineers operating NASA’s James Webb Space Telescope will answer questions about the mission’s latest milestones in a NASA Science Live broadcast at 3 p.m. EST Monday, Jan. 24, followed by a media teleconference at 4 p.m. https://www.nasa.gov/press-release/nasa-to-discuss-webb-s-arrival-at-final-destination-next-steps

All say 0.0 now.

I found this on YouTube by Nerdy Beardo Astrophotography Easy Star Reduction in Adobe Photoshop There is a StarXterminator Action Set here, at the bottom of the page. https://www.nerdybeardo.com/star-reduction-in-adobe-photoshop/?fbclid=IwAR1-euKwzvOZNWr76Z4ZsZKvuuGLIqPnJkoBj9OsleOTv16JccdKSAHbMTk Note: If running a trial version of StarXterminator , open an image first, run StarXterminator once, Revert the image, then run the action set, now you have control over the opacity of the levels. Also, Interesting results with an image that has been enhanced in Topaz Gigapixel.

This help? https://stellafane.org/tm/dob/ota/design.html https://stellafane.org/tm/newt-web/newt-web.html I once designed a telescope with a DOS version of Newt 21 ( A while ago 😉 )

Ran it through Topaz Gigapixel AI, just to see... Noise and Blur at about 50%

My amateur attempt for what it's worth. No filter stack. Logarithmic stretch (JR Astrophotography Macro's) in Affinity. Gradiant Xterminator, levels, curves, crop, vibrance, in Photoshop.
