Hi my name is Jay, new to all and any forums, lol. Not sure where to start so here I go. I have a few questions about Sirius the double star while observing through my Nexstar 4se telescope using a 2x Barlow and my neximage burst color. While I was able to capture quite stunning results of the star Sirius, this morning before sunrise, I was curious though as to if I might have incorrectly focused my scope on the star or if this image is a clear image of the star? I will attach a brief 7-8 second video I took this morning. It was the first time I had gotten to focus my scope on the star as it kept drifting before but I solved the drifting issue as a result of improper anti-backlash. But now back to the video, was wondering if any of you could help determine if I properly focused on the star because from what I see the star appears to be in the shape of an out-of-control atom in the video and at the center it is black, is this the observing of a quasar? Thanks for all the help in advance if anyone stops by thanks for the time and efforts here's the video. star.avi
I cannot emphasise enough my current feeling of happiness. For weeks on end, I've been looking for a seller in Japan that offers the HEQ5, but the effort was futile. Until now, that is. FLO (First Light Optics) ships to Japan! They really do! (Well, I will have to add 200£ to the mix, though). What makes matters better is that by the end of the year, I'll be able to afford the HEQ5, a good (F4) guide scope, a autoguiding camera, AND possibly a Coma Corrector! But then again, I'm thwarted by a question my beginner brain cannot answer. Assuming I have the HEQ5 perfectly Polar Aligned (Sharpcap Pro FTW) and I've balanced correctly (that biasing rubbish), what kind of subs will I be expecting with roughly 7-8 kg on the HEQ5 total? Clear skies, Leon.
My “not so bad” AstroPhotography & Astronomy site is up. Past the “all hat and no cattle stage”, it’s fast, clean, and full of new content. All of the images are mine and available under a Creative Commons Attribution-NonCommercial-ShareAlike license. New feature articles on getting started, earthshine moon photography, and printing astrophotography are in the “How to” section. http://astronomy.robpettengill.org/ The site features my astronomical images - mostly made from Austin with a small telescope or camera. There are seven ways to navigate and discover related images: featured, target, keyword, title, date, shared keywords, and shared targets. A slide show viewer pops up when any image icon in a related photos group is selected. I have queue of improvements in the works including more “how to” notes”, a full month of lunar images, FAQs, and links to full resolution images. Under the covers: It’s hard to make an image intensive site fast, so I built an XML model driven, correct by construction, static managed site. It takes less than a second to generate the nearly 200 files in the site from the XML content database. On the web, there is no slow wait for hidden database gears to grind or SQL Server error messages. Let me know what you think.
