I agree Pete

It has definitely been easier and quicker for me to place the 180 into the open rings which are already attached to the dovetail / saddle plate on the mount, but I use Tony's method for my Stowaway which I leave attached to the rings and dovetail plate. It is light enough that there is no problem lifting it into place in the saddle plate.

Mike,

I keep the rings for my little AP130EDFGT on my alt/az mount and have replaced the felt three times over the past 10+ years. I can remove the scope from the case and secure it into the open rings and be imagining Eagles in under 2 minutes. 

I simply view the felt wear as a maintenance matter not unlike changing the oil in my car.

For whatever it's worth I have been using Roland's method for setting my 180 EDT into the open rings, but I have found that the felt lining in the rings does not hold up very well when I install then remove the scope from the rings every time I get it out.

What I have observed is that the felt (or adhesive) is shrinking, and as it does so it pulls the felt away from the ring and stretches it out (see photo). I think that this is happening because the felt is getting exposed to moisture and dew when I am taking everything down at the end of the observing session. Once the felt it gets wet it shrinks. 

At some point in the near future I am going to have to replace the felt strips in these rings which are barely 2 years old. I believe that leaving the scope attached to the rings would minimize or eliminate this shrinkage.

We have excellent transparency at our observatory and the sky is really dark. The seeing (star scintillation) is not always good, but the Honders is a medium focal length scope (1160mm) so it is ideal for semi-wide field objects. I intend to go extremely deep with it and will be using the fast optics to gather detail in very faint structures.

Very nice Alex!  So you removed NB stars and blended in RGB stars?  Very cool. 


Re: The Beast is heading to Hawaii..

Wow that thing is a beast!  Having Marj there for perspective really.... well... puts it into perspective!

I also noticed the shiny mount, very pretty.  Looks like your QSI683 is mounted on the back.  Really looking forward to your images!  With the time difference you can get a nights sleep just about before you have to "wake up" and start imaging. lol.


Re: Calibration Frames for 130GTX

Chris White
 

Nick,

I have found the seam between the tube and dew shield to be 100% effective at blocking light.   The dew shield threads onto the back of the lens cell so there is a couple of inches after those threads where it's a pretty tight fit as well.  I've taken 20 min darks in the daytime and do not register any more ADU than when I take darks in the dark.  So you are good and don't need to worry about this.  (I assume you are locking the dew shield in the extended position and using the dewshield end cap)

As far as flats go, flats are used to even out the light fall-off towards the corners as well as disruptions from dust motes, etc in your image train.  That said, flats should be bias calibrated.  I'm not sure if it truly matters or not to take flats while cooled, but the finicky nature of CMOS ADC as well as that some cameras do not behave in a linear fashion I think it's a good idea to take all calibration frames (darks, flats, bias) at the same temperature as your light frames.  It's also important to make sure you use the same gain and offset as well.  While the impact of mismatched settings may be more or less insignificant (depending on the type of frame) I'd hate to think I've taken such care with my guiding, my scope and everything else only to not calibrate optimally and have the data suffer, especially since there is really no additional work required to get all the settings the same between calibration and light frames.  (I could think of the scenario where the next day its too warm to cool enough, but in that case maybe cool less for your light frames.  There is very little thermal noise difference whether at 0C or -20C).

One more thing to think about, is that thermal noise is very low on the latest breed of CMOS cameras (like IMX571 or IMX455) and it might not make sense to bias calibrate your darks.  I'm experimenting with this right now.  The ADU is so similar between a 0s Bias and a 1200s dark that there is a tremendous aount of clipping when dark frames are calibrated with a Master Bias.  So instead of the traditional (Bias Calibrated Flats) + (Bias Calibrated Darks) + (Bias) to calibrate my Light frames, I'm starting to use (Bias Calibrated Flats) + (Uncalibrated Darks) to calibrated Light frames.

This may not apply to cameras that have excessive amp glow like the 294, or 183 chips.  In this case you might need to calibrate the Flats with a dark flat. 

Anyway, more info that you were asking about, but hopefully helpful.

Yes, I have evolved the way I set up my 175 over time to set it up quicker without issues. In this video from 2016 I used this technique  https://youtu.be/JHN3eqDzcRU?t=276  (should open at correct location in video). It was in park 5 position. Worked great BUT had the weights out off the side and needed to use the chains as seen in the video. I used to use a light stand as seen at this point in the 2016 video  https://youtu.be/JHN3eqDzcRU?t=226  which is much like what Jim does.

But then I tried what I now do in park 2 position. Either way I have to lift the scope. BUT, no chains needed and the CW's are down. No weight off to one side of the mount for me anymore and less equipment needed to setup.

thanks  tony

You might be horrified to see me (with  help) mounting a big scope with the counterweights held up by a step ladder. Holding the counterweights up while removing the scope is important because once the scope is removed, the counterweights will swing down potentially crashing into me! I don’t suggest anyone use this technique but, I have used it successfully for decades, without incident.

My video is with a 175 refractor, not what you mention below. Various scopes may require other techniques. Also, what one person can accomplish another may not be able to. Just showing my way. I have absolutely no problem with the way I do it. We are talking about perhaps 50 lbs. That's not much weight, at least for me. I do consider myself to be in good shape though. I have a treadmill in my living room which I use twice a day and stay very active.

You will see that I have a handle at the center of balance. I can easily pick up the scope with my left hand and use my right hand on the base of the dovetail. Lifting it up and placing it in the saddle as I describe. The handle gives me a secure grasp of the scope. Depending where I place my mount on my property I may have to carry the 175 several hundred feet to get it to the mount from inside my house. No issues. A simple lift onto the mount is nothing after that.

No way would I try to mount the scope with rings opened and laying the scope in them. But that's me. Not everyone would agree.

BTW, send me that brand new PlaneWave 14 and I will demonstrate. One caveat, you won't be getting it back :)   {I wouldn't own a C14 or a Meade 16}

Calibration Frames for 130GTX

Nick Iversen
 

I have been taking long exposure dark frames with my 130GTX covered at each end to prevent light leakage. But I just realised that I haven't been covering the gap between the tube and the dew cap. That gap is almost airtight. It doesn't leak light does it? I will cover it from now on however.

Speaking of calibration I have seen it said that for flats you don't have to cool the camera because exposure is too short. That surely can't be right for CMOS can it? I always cool my camera for flats.


Re: The Beast is heading to Hawaii..

Close within several hundred miles. You must have been in some strong headwinds flying from Hawaii to SF as the average time is around 4.5 hours. Also not fair to judge distance by airtime due jet stream can be over 200 mph going east and rarely seen spanning the entire continental US. Try flying to Hawaii during a pineapple express. Flight times can exceed 7 hours. -Best, Robert

Having recently acquired a scope from Hawaii, I have learned you can ship by FedEx “ground” to/from Hawaii, and it’s pretty close to the air delivery options, given the paucity of currently available courier trucks that cross the Pacific Ocean.

If going by ship it might take a while for delivery.
Might want to go by air instead.

... where it will gather photons and help to test software and hardware for AP. It has been cloudy here all month with no end in sight, so it is being shipped off to sunnier and warmer climes. My beautiful model is there for perspective to show just how big it is: 1600 mount with 120lb of counterweight and 305mm F3.8 Honders astrograph. Solid as a rock on its ATS pier. Hope to get some images in the coming week.

Can’t wait to see the images. What do you plan on using for an imaging train?

We have excellent transparency at our observatory and the sky is really dark. The seeing (star scintillation) is not always good, but the Honders is a medium focal length scope (1160mm) so it is ideal for semi-wide field objects. I intend to go extremely deep with it and will be using the fast optics to gather detail in very faint structures.

WOW!!! 

 

Should be the proper setting for the scope!

 

Looking forward to Pacific based Honders images.
