Here is a wonderful Crab.  Same thing, 180 seconds, stack of about 5.

John,

 

Very nice images from the other night.  Your skies appear to be well suited to the LSX2.  Too bad you don't have a LSX2C to compare.

Thanks Don. I don't miss color much at all really, the simplicity of mono is quite alluring imho. But yes, would be cool to compare the color LSX2C.

I agree John.  I started out in video with a b&w video camera and found going to a color camera a bit intimidating and a lot more work.  I currently use my b&w video camera with a narrow band filter on a monthly basis when the moon is high and bright .  It's a nice change of pace to be able to capture objects with simplicity of control and b&w detail is very refreshing and detail abounds.

I'm with you guys on the mono.  And the narrow band filter makes it even better.

I have been away for awhile due to having so many mount issues over the last few months.
I purchased a floor model iOptron iEQ45 and discovered that it was a first generation model and apparently suffered a bit of abuse from the general public.
I have had quite an adventure working on this project. 
Needless to  say I have had to completely rebuild the head. 
This includes all the circuit boards, hand controller and upgrading the RA gearing to a high precision worm gear. 
It has taken some time but I am happy to report that the mount is giving exceptional results.
I use an Astro-video Systems MK IV video camera and before the mounts refurbishment and upgrade, the tracking ability made it useless for anything above integration 256.
Using any of the cameras internal stacking abilities turned on would always show star smear and other artifacts. 
This made any of my SCT and MCT telescopes practically useless at their native F-stop.
Anyway I am back and with my first captures with the mount functioning at it's best. 
I do guide at the long integration setting of 1024 and having internal stacking on at 5 frames the first image appears after 85 seconds. 
Here is the first image and one of my favorites.

Great images John, your mount certainly appears to be back and even better than before. Isn't it a good feeling to get nice round stars?

 

I think I'm in somewhat the same boat, after 5 years or so of use my CGE needs a little TLC ... specifically new worm bearings.

and another.  No amp glow mask was used.  Temp was -14C at the start of the broadcast and the cold seemed to have minimized amp glow and hot and warm pixels.  Transparency was only so so as there was ice fog forming.  Seeing was also it's usual shabby self.Attached File  2014.11.17.015618.jpg   175.04KB   14 downloads

Nice images Dwight :bow:  Could you explain the exposure MC mode/procedure please to us Lodestar users ?  Does "Integrating: 12 of 90sec continuous shooting: frames 2 of 2" = 180s exposure and are these the last two frames from the sequence of 12?  Or is the total exposure of the image different?   TIA

Thanks Maurice.  The 12 of 90 seconds is the exposure time counter - that is 12 seconds into the next exposure.  The display is of the previous exposure which is an average stack of two.  When a frame is grabbed in Miloslick it freezes what is on screen.  Live the countdown timer continues on.  When selecting average in stacking mode, the effective exposure is not lengthened as it would be by sum.  Noise is reduced very well by it.  Miloslick has a sum stack function but I don't think I have used it.  Up to 10 frames can be stacked and I usually choose rolling so the first frame is dropped as subsequent frames are added.  This is handy when one frame is out of sync and trailing is showing.  The next frame usually corrects this when the bad one is dropped.  Not a problem if you guide which I don't.

Aperture is clearly helping here Dwight. :) btw, what is gain set at?

AGC was at 3 Curtis.  This is my usual setting.  Very occasionally I have used AGC at 0.

Great images Dwight.  The lack of amp glow is impressive.  At AGC 3 I definitely would have amp glow at these integrations even though my X2 is fitted with a Class 0 sensor.

 

What mount were you using?

Hi Don:  thanks for the feedback Don!  I was using the club's AP1200 mount.  I can squeeze up to 4 minutes + out of it with 3 minutes being consistent.  With a shorter focal length it would be essentially unlimited.  Interestingly enough, I can replicate those times with my Tak EM200 at half the price.  Who says the cold isn't good for something!   Aside from reduced amp glow, there were very few hot pixels and no warm ones.  I was surprised and now won't hesitate to go out into the cold dark night - as long as it isn't -30. :lol:

My first try at this over the weekend! I was learning a lot and managing many things, so I don't have all the details, but this is what I do remember...

 

The moon was through my first attempt using the 9.25 SCT, I definitely didn't have something right, seems blocky to me. I tried Jupiter the same night but didn't get much in the way of results.

 

Last night I had what I think is good success using the FC60 to get M42. I think that was 12 seconds no stacking. I tried the Pleiades but couldn't get everything in the frame. When I tried the Mallincam focal reducer I couldn't find a setup to reach focus, it was just between my shortest diagonal and no diagonal. Extensions on order.

 

Then I switched to the 127 Mak and had much better success with Jupiter.

 

I was very excited to get anything at all, very excited to try more!
