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.
Just wanted to share my bloodmoon experience with you in this blog.
It was quite challenging, ice on my balcony, camera falling out of telescopes and tracking challenges.
But in the end it was a wonderful experience, you can read it here:
and i've included a (gittery) timelapse + final image.
Please let me know what you think, should I keep the stuff that goes bananas for myself or share it with you folks?
After a fistful of stars from the other night here's a few stars more from last night . Transparency was poor, though and I had to give up in the end. As well as fitting the Lightwave 0.8x to my 80 mm F6, I've also transferred the scope to the Heq5. Although I think Sharpcap is great for live stacking it won't always detect enough stars to auto align which means I have to use guiding. I can see plenty of stars on the screen but Sharpcap refuses to share my view! I've tried noise reduction and boosted digital gain etc. I think I'll try the v3.2 beta. I might try without the uhc in future as it probably cuts out too much light when combined with the IDAS D1. All live stacked with darks and flats. Some were guided.
M35 - 20 x 30s with IDAS D1 and UHC:
NGC 2420 aka the Twinkling Comet Cluster, 30x30s:
Jellyfish Neb, 40x30s:
You can just see the edge of it with some stretching!
More apparent with overstretch but - yuk!
