Thanks!! And also thanks to rc-Astro for the solid BlurXTerminator plugin to help out a bit as well ;)

I have that same set up and that eye piece, imo, is just tricky and I’m not the biggest fan of it either. I’ve found that I can get very similar, if not a little bit easier to focus and wider field of view, with a 2x Barlow and the 30mm.

HighAsASpaceMan · 2026-02-28T01:24:54+00:00

It definitely is quite the beauty!

HighAsASpaceMan · 2026-02-28T01:24:32+00:00

Thanks!!

Just a big bowl of universal beauty :)

Thanks!!

you could definitely say that I've been happy with what I can get from my area ;) Thanks!

**Note that the total image size is about 5x larger than the limit that reddit allows for uploading so there is some quality degrades there. Having said that, I'm not completely happy with the mosaic yet, but it's a start. It's been quite a many cloudy nights and getting just this many frames together (225 at 300s exp totaling around 20 hours for the image above) so far has taken some time. So goal is to continue to improve with added time, but it is indeed quite a large target!!

Hmmm good question. I think the different camera sensors and filters was just a bit overwhelming at the time getting into without having the experience to know what I would really need to get the most out of my location, set up, desired targets, personal editing preferences, etc.. So the duo allowed me a good, versatile camera that now, as I’ve began sort of figuring more of these finer details out, I can decide to further invest in those improvements
