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 ...

Quick peek at active region 7/12/18 with the 10" LX200

Only able to sneak a couple of quick captures as the sun was dodging in and around some clouds. I figured it was time to pack it up when the thunder started https://www.cloudynights.com//public/style_emoticons/default/storm.gif . Seeing was fair to average on the whole with some gusting winds, still...

Re: Large filament on June 25

Re: Help! Tiltadaptor and Lunt LS50..

I did not notice any change in the available back focus when I changed from the stock helical focuser to the Feathertouch on the LS50. I went down this road too.

Re: Help! Tiltadaptor and Lunt LS50..

Unfortunately the lack of back focus is one of the limiting factors in using the LS50 for imaging, and was a big part of me moving to the LS80. I could get it to focus with the 50 by removing the B600 nosepiece and screwing the blocking filter directly to the back of the focuser with a T adapter rin...
