Straight range-Lunar domes?

Posted By Mike Wirths
Hi all,

Shot an avi of the straight range on the night of the 30th, I just processed the avi yesterday and there seem to be some features that look like lunar domes to me, are there any avid lunar observers out there, is that what they are? I shot the pic with my 18" Starmaster, a 3x's televue, toucam. I labeled the 3 dome features, can't seem to find any refrence to them on the APLO site yet. I e-mailed the lunar domes coordinator of ALPO so I'll have to wait and see! They kinda form a triangle around a crater that is approx 1.5km in diameter (according to guide 8).
I like the shot since the straight range is one of my favotrite lunar features.

cheers

Theophilus & Cyrillus

Posted By Mike Wirths
Hi all,

Great to see so many amazing pics lately, from Leroi's fabulous Jupiter and also lots of superb deep sky images!!
Here in Ontario Canada its been typical spring weather ie lots of clouds and rain especially at night of course!!
Last night I tried to get some lunar shots in despite lots of at times thick cirrus clouds and only 5/10 seeing, but hey I was desperate!
The only shot that half way turned out was of Theophilus and Cyrillus using a 3X's televue barlow and my 18' Starmaster. I had to use about 40% gain and a lot of brightness/gamma to compensate for the clouds, hence the contrast of the image is poor but it still shows a fair bit of detail. The stack is 130 out of 600, done in Reg 2 processed in Images Plus.

cheers and hoping for better weather!

1st light Atik webcam/Albategnius shot

Posted By Mike Wirths
Hi all,

Well I finally got my new B&W Atik instruments cooled webcam from the UK. I choose this as it would allow me to do long exposure shots on bright DSO's such as planetaries, as well as lunar shots.
Thurs night finally cleared enough to give it a test drive, but the seeing was atrocious, Jupiter barely showed the N & S Eq belts! Still I shot a sequence on the moon using a 3X's barlow on my 18" Starmaster. The sequence looked very clean, almost no decernable grain. The pic is a stack of 30/600 done in Reg2, captured in K3CCD tools. Its the crater Albategnius, right beside Ptolameus (I wanted to do it but the FOV was too small.). Maybe the next 2 nights will give better seeing, it sure can't get much worse!

cheers

Atik cam Stadius area

Posted By Mike Wirths
Hi all,

Got some ok seeing last night (5-6/10) but it was gusty so hard to keep stuff in the FOV! Hope you people don't mind a bunch o lunar shots cause I went kinda crazy trying out the new webcam. Heres Stadius and craterlets.
Stack of about 120/600 3x's barlow 18" Starmaster. I like the new camera better than the Toucam seems to have a lot less noise.

Atik cam Clavius

Posted By Mike Wirths
Hi,

heres my Clavius, not as nice as Wes's but still fairly low noise, I think I overexposed it a little too. Just have to wait for some better seeing! Stack of 120/600, 3x's barlow, 18" Staraster. Reg 2 and Images plus.

Interlace lines?--Help!

Posted By Mike Wirths
Hi all,

I noticed in my raw avis that the single frames have a noticable pattern of horizontal lines on them, I have no idea how to get rid of them, they even show up on my processed pics....very annoying! Are they some kind of interlace lines? I'm using Registax 2, I usually uncheck the color box. I attached a single frame from my recent pic of Stadius.

thanks

Plato-reprocessed/neat image software

Posted By Mike Wirths
Hi all,

With lousey seeing the norm lately and work obligations, I've turned to old images in the hope of squeezing a bit more out of them. My Mar 30th shot of Plato is a fair bit more detailed and less noise thanks to NeatImage software which worked well in this case as the smooth crater floor of Plato gives a sample for neat image to subtract the noise.

see what you think
