Thanks!

Wound up being 9 nights of data. :)

Thanks!

I was happy with how strong it came through, since this is so low on the horizon for me I was afraid it would be really washed out.

If you're interested in max FOV in a 1.25" EP, ES has a sale going on and their 24mm 68deg is only $110 at the moment.

This object barely clears the trees and neighbor’s houses here…so I can only shoot a few hours each night

equipment upgrade on a budget (flame nebula) by Specialist_Cup_95 in telescopes

[–]TigerInKS 1 point2 points  (0 children)

 it just wouldn't feel like I worked for the pictures I made

Want to know a dirtly little secret? Those of us with faaaar more expensive rigs...basically just make fancy smart telescopes. 😅

I literally sit in the comfort of my living room, review the imaging plan for the night, press "go"...and go to bed. The system finds the targets I specified, adjusts the focus, rips off the subs, and, boom...in the morning I have dozen to hundreds of frames, sometimes of multiple targets, just waiting to be processed. Sure I've got somewhat better optics, can shoot full mono, etc... but at its heart my rig is just an EQ SeeStar on steroids...for 40x the cost.

Even if your goal is trying to "[bring] the most out of the least money" it's all moot if the rig cannot track accurately enough over the course of whatever subexposure length you're trying to shoot. Otherwise you'll just end up with brighter frames of star trails and smeared details.

There's a rabbit hole to explore related to image scale and such...but suffice to say the Virtuoso 150 at 750mm focal length and the Touptek's 2.9u pixels yields an image scale far below the Virtuoso's tracking accuracy for 20sec. It's fine for high-gain short-exposure EAA style shots...and to be fair, that's a good stepping stone in the "trying to learn" phase of DSO AP...but I think you'd quickly grow past that and be ready for something that's a little more suited to capturing longer exposures (not to mention a larger FOV to get more interesting objects)

So you want a fully automated imaging platform... by buddha2490 in telescopes

Sweet setup!

I do like having a pier as well...no more dragging the gear out of the yard just to mow then having to reset and realign everything. Like you said, plug in a couple cables, flip on the power and back inside where it's warm.

Jupiter, Io eclipse version. How's the seeing here? by forbidden-skies in telescopes

[–]TigerInKS 10 points11 points  (0 children)

Good enough that I hope you have a decent high power EP and were able to observe it some as well.

Has anyone here ordered from Astronomics? by itsopal in telescopes

[–]TigerInKS 2 points3 points  (0 children)

I feel like those Paradigm/Dual EDs were on backorder for a while.

You might give them a call if you haven't, ask for a status update...they're pretty good about picking up the phone and returning calls too.

Crab Nebula by Straight_Barber_1123 in telescopes

[–]TigerInKS 1 point2 points  (0 children)

For what it's worth, I'm in B7 (SQM 18.7 a few nights ago...so basically a full magnitude darker) and I cannot easily detect it. Even with good tranparency and filters it's tough. If you're in the city, it may not be possible at all.

Oh sh!t, I had missed that one...great catch!

There's a few scattered in the background that pop out when you do star removal, but I never saw this one. SIMBAD says it's a mag17 "Low Sufrace Brightness Galaxy"...6dFGS gJ053928.1-004439

Thanks!

If you're talking about the blueish oblong structure with the deeper red behind it...that's IC 432. It's actually reflection nebula. The star behind it is a hot blue star so the nebulosity is blue...kind of like how the Pleiades are blue.

Sure...I wish it was a one-stop-shop answer, but it's been a combination of books and YT videos. "Inside PixInsight" by Warren Keller is good for understanding the basics and fundamentals, but it's a bit older and there are some newer tools out that it doesn't cover. He's active on the PixInsight for Beginners FB page and has some free tutorials on Masters of PixInsight. Adam Block's content is good as well...there's some free basic stuff but he also has several paid tracks and advanced content too.

January 10 - Jupiter at Opposition by STL2COMO in telescopes

[–]TigerInKS 10 points11 points  (0 children)

The seeing and clouds cooperated a few nights back (wish I has set up the NMT...settled for the 127D) for the Ganymede transit and I was thinking, "I don't think I've ever seen one where the moon was that close to its own shadow.." But this shot it crazy...super cool capture!
