Re: SolarQuest review

Has anyone tried the field de-rotation feature in AutoStakkert? Seems like it should be able to compensate, however I've never tried it (don't have an alt-az mount).

Hi, Alex

My favorite is your first prominence image. Well done.
What does the 9.9 in the title mean?

Lou
I puzzled about that also until I looked at the date in the images, I believe it is the date of imaging.

Exploding arch prom from 9/19

I was messing around with a different optical train to try to get smaller pixel scale per Valery's recommendation, and figured I would grab some sequences of that nice arch prom that Marty put up when I noticed it changing, literally as I was trying to get focus! At first I thought it was my eyes or...

A few surface grabs from the weekend

Relatively steady morning skies and some clearing of the forest fire smoke finally made for some good conditions over the weekend, at least until the Quark Combo decided it was too hot to stay on band. I'm starting to wonder if I can stick a Peltier cooler and some radiating fins somewhere on it. No...

Re: What camera do you use?

Hello Rainer, The Intereference Eliminator is a camera tilter. Newton rings results from interference between reflected light from two surface close together, so it is usually the Quark or barlow and the camera cover glass; therefore you need to tile the camera relative to the Quark, not the ERF. Th...

Re: What camera do you use?

QHYIII 174 for long focal lengths, ASI1600MM for Lunt 80. Lots of Newton rings with the 1600, but cured with a Daystar Interference Eliminator.

Re: Dragon!

Hi Alex, I used Photoshop's MagicWand selection tool to select pixels of the brightness of the disk, so it follows the brightness outline. I did smooth and feather it a bit. I was too lazy to shrink the image and try to draw a circle of the correct size like I usually do to blot out the disk. I shou...

Dragon!

Finally had good enough seeing the other night (although not for very long!) to tweak the collimation on the Meade 10" on an actual star. Not far off, but it seems to have made a significance difference in sharpness, most noticeably on proms. Now we know from whence dragons come... AI PS 083455_Sola...

Re: Large Filament | 150mm & Quark | 6562.8A | July 24th 2018

Looks great! My seeing has been just the worst recently, and the 110F temps don't help either - Quark won't stay on band. Why is astronomical equipment painted black?!? Everything is painfully hot to touch and the bubble level on the Mach1 seems to have boiled off. Time to drop back to the Lunt for ...

Re: Quantum 0.4Å PE Filter

I think he means the chart here:

http://www.televue.com/images/TV3_Image ... crease.jpg

It shows very little variation of the 4X with distance - it's a little under 4X at 0mm, seems right on at 25-30, and is maybe 4.4 at 100mm

Mosiac of the active region 7/16

Had a go at putting together a 6 panel mosaic of the fading AR2713, was relieved to see it actually come together OK. Using a shorter 15 sec capture time seems to help with the softness of some features, seeing did require me to stack somewhat fewer frames - this was a 500 frame stack. JPGified for ...

Only able to sneak a couple of quick captures as the sun was dodging in and around some clouds.
