To mask or not to mask, that is the question

Roland Christen
 

Hi Astronuts,

This is completely off-topic. My daughter sent me this funny video which attempts to answer today's most pressing question. What are masks for and do they really work? The video is funny and completely non-political. It's in the style of the old Myth Buster's TV programs where they were always blowing things up or burning them down. So, if you have a few minutes to spare, sit down and watch this:

Love ya all and stay healthy,

The keypad always had the latest data for planets.
Where it was lacking was in the data for stars which lacked the extra decimal points for the highest precision and also lacked calculations for precession.

Thanks, Roland.
 
I’ve been watching Christopher Go post his images over the years and have regarded them with a great deal of envy.
 
From a presentation he gave for Woodland Hills, it seems he uses an LRGB approach with a monochrome camera and registers everything using WinJUPOS, which I haven’t used yet.   But when you add up 30 sec for each filter and recognize he takes several groups, it ends up being a healthy amount of time.  (I should probably send this question to him!)
 
However, I thought I had remembered comments posted (by you?) about the planetarium program in the keypad not being quite up to snuff with the latest data for planets. I think it was one of the items that was to be upgraded in the new firmware/software.  My question for Ray was whether uploading ephemeris data for the planets would provide a measurable improvement in the pointing and tracking of the planets at long focal lengths.   And, as a bonus question, how did this play with the APPM modeling – which I believe is principally focused on star pointing and tracking.
 
You can tell we have bad weather here, or otherwise I’d be out there answering these question for myself with some theory to practice evolutions.
 
Thanks in advance for your consideration and thoughts!
 
Best wishes for good health and clear skies!

Re: large alignment error with polemaster & mach2

Jim Hawn
 

You indicated:
"I need to polar align my Mach 2 very quickly"

To echo what many others have indicated, consider using the RAPAS to initially polar align.  With a little practice, this takes about two minutes.
Following initial PA, take advantage of Sharpcap Pro's polar alignment.  With a little practice, you can achieve a <1' polar alignment in about two minutes.
Thus, in less than approximately five minutes from start-to-finish, your Mach2 is decently polar aligned.  Add a minute or two if you want to fine tune to <10".
I'm reporting from experience, not conjecture.
If you define "very quickly" as 4-5 minutes, perhaps this is a solution for you to consider.

Hello,
I need to polar align my Mach 2 very quickly to save time on field.
I thought Polemaster would have been a good choice but I cant get a good alignment with it (I am ways off)
The procedure goes very well, till the end, including the precise alignment step, but I have drift in my images.
running the Polemaster twice results in a small change.


I am not using the refraction calculation , as I leave at 42 deg latitude: can this be one of the reason?

my aim is to shoot 10 min subs unguided (@790mm focal and 1,6 arcsec/pixel resolution).

I still don't have my OTA ready so it is difficult for me to check with the drift method for the time being ( I can borrow a dslr and C8)

Would the RAPAS be a better solution for my needs? 
I understand it can be mounted on the MACH2 using a dovetail, with repeatable accuracy.
Is the accuracy enough for imaging and how it compares to Polemaster?

Thank you,
Andrea

Pelican Nebula and M33

Robert Chozick
 

I got a few more images from my test trip for my new ASI2600 CMOS color camera. 

Pelican Nebula

The bright stars in the Pelican got blown out and really unfixable with the shorter exposure subs so I learned that 5 min at f5 is too much with this camera when bright stars are present.  There was also a reflection in the right upper corner that I think I can fix by bringing the UV-IR filter closer to the sensor.  On the FSQ the CA-35 camera adapter allows a 2 inch filter to be screwed in but it is 30-40mm away from the sensor.  I am getting a ZWO filter drawer to bring it closer.  Hopefully that will fix it. 


M33

I needed more data on M33 and some Ha but I was surprised at the quality of the data for only 2.5 hours.


I need to try to always get more data on images.  In the past I have wanted to get a lot of images on every trip since it is so rare I go but I am going to try to get at least 5-6 hours of data at f5 and 8-12 hours at f8 from now on.

Re: large alignment error with polemaster & mach2

Marcelo Figueroa
 

I've used the polemaster with my Mach1 the last couple of years without any problem (I haven't been able to test the Mach2 yet, it's winter here).  A couple of things to keep in mind:
 
- Make sure that looking at the mount from the front, the USB connector of the polemaster is pointing to the left.
 
- Did you perform the procedure with all the equipment mounted? If it is done without the equipment, adding the extra weight later may introduce small changes.
 

You can also try the PHD2 polar alignment procedures (3 in fact, Drift, Polar Drift Align and Static Polar Align) which is free.

Andrea,

Your original post message is a little confusing.

First you said:

"The procedure goes very well, till the end, including the precise alignment step, but I have drift in my images."

then you said:

"my aim is to shoot 10 min subs unguided (@790mm focal and 1,6 arcsec/pixel resolution).

I still don't have my OTA ready so it is difficult for me to check with the drift method for the time being ( I can borrow a dslr and C8)"

You don't have OTA ready but still get drift in your images? How can you get images if you don't have OTA ready?

What scope were you using that's giving you drift and are you trying to image unguided? Also you said you are aiming for unguided imaging at 790mm focal length which can be very hard to do assuming you are not using pointing model with APCC-Pro. Are you using pointing model yet? If not, I would not expect absolute encoder alone to get pinpoint stars without the help of pointing model even with perfect polar alignment due to many external variables like refraction in the sky, flexure, etc.

So, if you polar align using PoleMaster and its software and use guiding, then I would expect excellent images. Like others said, I would prefer Sharp Cap Pro as well as it's not only accurate but super easy to use. If you already have PoleMaster, then you may not need RAPAS because PoleMaster with Sharp Cap Pro is really good and quick.

Can you clarify your original message a bit more?

Peter

Re: large alignment error with polemaster & mach2

Cheng-Yang Tan
 

One thing that I use SC + PM camera for after polar alignment is monitoring sky conditions. IMO, it’s a complete waste to have a camera just sitting there and doing nothing after polar alignment. I have the 
PM camera mounted on the saddle and thus it is always pointing to where the imaging scope is pointing. Then I have SC do “multistar FWHM measurement” of all the stars. It’s a good measure of whether the sky is deteriorating during the imaging session

SharpCap Pro is a critical tool for me. I use it for controlling my QHY174M-GPS cameras when doing occultations. The price is dirt-cheap and I would still pay for it at four times the price. It is the only camera control program that is capable of collecting the GPS timing and location data from the cam and putting it into the FITS headers while collecting up to 450 frames a second. If course most of the time I am collecting frames at about 4 frames per second.

It's an amazing program for the price. And for many people, the free version is sufficient.

OFF TOPIC: Duplication of Group messages - tagged as “[Edited Message Follows]”

Joe Zeglinski
 

Repetitive Duplication of posted forum messages:
 
    For example, searching through this group’s posts over the past 2 years, I found from “Jimmyjujames” ...  6 edited copies from 1/11/2019, and yet another 6 copies of the very same EDITED message a week later on  9/11/2019. I don’t login via browser by download emails via client, so is this  “EDIT option” a part of the Groups.IO system?
Nothing was “actually edited” in any of those duplicates, not even so much as a “comma replacing a period” ! This is just one example of dozens of such repeating posts.
 
    The original AP_GTO group was  moved from YAHOO to Groups.IO much later that year,  on 24/10.2019 – so the problem is likely not the fault of the Groups.IO server app, or of the AP forums, but perhaps the email client app used to post their messages. I have found a few other members, on about a dozen other Group.IO  forums, so the duplication is not unique to the Astrophysics forums  membership, though I would say the majority are here, owing to its large membership.
 
    Scanning my saved emails list for this [AP_GTO] group, I have come across several other members – using various ISP’s (Gmail, Yahoo, Outlook, etc., even Groups.IO) – extra emails which I usually have to delete, wasting time and disk space, since they seem to be useless Duplicates, made in error, over this sampled timespan. The EDITED posts are good to see, if they had a REASON (option line) attached for it, but the vast majority, with ray’s being an exception, are just copies, without any changes made.  Folks, please exercise some care.

    Are duplicates with the heading  “[Edited Message Follows]” – coming from their (common) smartphone email apps, or from their browser, which might also be the same one, for all those members whose email was repeatedly sent with just the text line  “[Edited Message Follows]” added at the top?

    A few of the old posts saved in my group  Live Mail folder , really are valid  EDITED duplicates, since I found a couple which had yet a second attached  line,  added by the editor below that first one,  stating for example  “[Reason: Added info]”.
Perhaps some members keep clicking on the SEND in their browser, and multiple copies are generated by the smartphone email app or browser – or their mouse button/screen-tap,  is sticky. Certainly doesn’t seem to be the fault of the Group.IO server, based on our transition date being later than the oldest occurrence of “[Edited Message Follows]” insertions.
 
    There may be some commonality among all those duplicates generated by several group members.
Otherwise, there is an on-going problem for the rest of us, who have to check &  (possibly) delete such suspect duplicates,
 
    So, please check your own device – surely you must be seeing your own duplicates sent back to your device,  from [AP_GTO} or other Groups.IO.

Moving to a new imaging laptop #APCC

Dean Jacobsen
 

I am moving to a new imaging laptop in a couple of days and will be installing APCC Pro, ASCOM 6.4 and the AP ASCOM driver on it.

I found the hidden C:\ProgramData\Astro-Physics\APCC\ directory.

I wanted to move as many of the existing settings over to the new computer as possible so I don't have to go through and set everything up again.

I do a new model every time I set up so I don't think that I need to move the "Models"

So, this is what I think I should move from the C:\ProgramData\Astro-Physics\APCC\ directory:

- the HRZ file that is my horizon limits on the current computer,
- the two MLM meridian limits files that I created.  I assume that the default MLM file will be in the new installation already,
- the "Settings" document - replace the default document in the new installation with this one from my current computer.
- the same with the SiteList document

I don't think I need the "Backups", "Logs" and "Models" folders in my new installation.

Is there anything else that I need to transfer over to the new installation?

Re: large alignment error with polemaster & mach2

Hi Rolando,
   I think my "Unfortunately, SC polar alignment costs $", is more of a lament that the software that comes with PM does not seem to be as accurate and the op has to spend money to get it to work better.

  To be clear, I don't begrudge people making money from doing software work.

Everything should not be zero cost. Writing software takes time and expertise and should be rewarded. If everything is zero cost we will all be forced to become subsistence farmers scraping a living from the soil.

I’d suggest trying Sharpcap with the Polemaster camera. I’ve always found Sharpcap gives a better PA than the Polemaster software. An advantage of SC is that it gives an alignment error when you are adjusting alt and az which is absent in PM software.

Unfortunately, SC polar alignment costs $ and is an annual subscription, but it’s cheap.

As usual YMMV

Hello,
I need to polar align my Mach 2 very quickly to save time on field.
I thought Polemaster would have been a good choice but I cant get a good alignment with it (I am ways off)
The procedure goes very well, till the end, including the precise alignment step, but I have drift in my images.
running the Polemaster twice results in a small change.


I am not using the refraction calculation , as I leave at 42 deg latitude: can this be one of the reason?

my aim is to shoot 10 min subs unguided (@790mm focal and 1,6 arcsec/pixel resolution).

I still don't have my OTA ready so it is difficult for me to check with the drift method for the time being ( I can borrow a dslr and C8)

Would the RAPAS be a better solution for my needs? 
I understand it can be mounted on the MACH2 using a dovetail, with repeatable accuracy.
Is the accuracy enough for imaging and how it compares to Polemaster?

Thank you,
Andrea

SharpCap Pro, the version that has the polar alignment tool, is actually a very nice little program.  Lots of stuff you can do with it.  It will run my camera, manage the cooling, run the filter wheel, etc.  The polar alignment tool is very cool and easy to use.

Hi Jim,

 

Thanks for your thorough and helpful response.   Your image of Saturn is spectacular and indicates that while I’m following a similar workflow to the one you described, I’m not getting the same kind of results.  Hence the reason I was searching for some improvement.

 

Since your results are so far superior, I’ve sent you a note directly, explaining my challenges in a little more detail and asking you to share some of your secret sauce.

 

Thanks again.

 

Cheers,

Greg
