That is a super shot! In such a short time it is doubly impressive!

Re: A quick Draco Triplet

 

Roland I use the ASI6200MC (full frame color) and do 15 minute subs on my SV80mm f6 refractor

I generally don't have an issue with saturating the stars

Compared to the # of stars in the final image https://www.brianvalentephotography.com/astrophotography/i-DwvmwzK/A  I would say total star saturation is a ways off for me.

This is unstretched sub showing some star saturation on the larger ones and a few others, but comparatively few stars are full well

Probably the reason is that my exposures are 5 minutes long. I'm still in the CCD mode of long exposures = better sign/noise. I guess I will have to experiment with short exposures for my shots.

Very nice image. Even though you posted a low res version, I can tell that your setup has potential to make very highly detailed images.

As a travel imager the late sunsets of summer can make it a real struggle to shoot on a work night, but who needs sleep anyway?  I managed to snag just shy of two hours on the Draco Triplet last night using my 12" F4 Newtonian on the 1100GTO.  This will hopefully be my last image using the trusty 1600MM-Pro as I have a 2600MM-Pro arriving tomorrow.  I shot an hour of Luminance at gain 76, and 15 minutes each of RGB at gain 139 using 60 second exposures for all.

Hi, Chris:

I have been watching your Jupiter and Saturn imaging for years and enjoyed your presentation at NEAF some years ago, and have long admired your dedication and work. But these two images of Jupiter raise the bar. They are extraordinary! And to think that you were contending with variable seeing post-monsoon—even more amazing.

Thank you for sharing these with us,

Eric Baumgartner

Re: Lunar eclipse composite

Karen Christen
 

Hello Rahul and group members,

 

There are 3 ways to include an image in a message on the forum:

  • You can include a link to a file (such as on Astrobin or Imgur like Rahul did).  This is a terrific option because it does not cause the email to be a large size (which can wreak havoc for some folks’ email systems) and your file does not lose any of its brilliance.
  • You can post your pic or document in the Photos or Files section of the Groups.io page, and then include a link to it in an email message to the group.
  • You can attach a file to your email.  Be aware that Groups.io will likely resize your attached file so it may no be as gorgeous as your original.

Re: Suggestions for Stowaway Tripod and Head

wes Bolin
 

FYI I own a Stowaway and have a portable set-up.  I tried several iterations and I have ended up with a configuration that meets my visual "requirements".  I have a DiscMounts DM-4 mount with encoders and SkyCommander computer.  It attaches to the 3/8 stud on my Sirui-3004 tripod.  The tripod is rated at 55 lbs capacity and
has a hook under the top plate that I hang a stabilizing weight for more stability.
The tripod is good for portability with a minimal size and weight.  But, some of my viewing does not need the compactness, so I use my Losmandy HD tripod with the DM-4.
In order to mount the DM-4 on the Losmandy tripod, I had a machine shop make a steel adapter that fits on the tripod and has a 3/8 inch stud for the DM-4.  It weighs about 10 lbs. 
 I use a threaded coupler on an eye bolt, and attach it to the tripod hook and the steel adapter, and hang it under the tripod. It gives me much more stability/lower damping time when I use the compact tripod, and move it to the Losmandy tripod when needed.  I don't "need" the weight but it improves the stability.  I also use Dryer vibration pads under the tripod feet if I am on a hard surface.
One case for the mount, a bag for the tripod, and another bag for the steel weight, vibration pads, misc. hardware, and stuff.  I absolutely enjoy taking the Stowaway away from my light dome out into the countryside for viewing with a quick and easy set-up and tear-down.  I hope you enjoy your Stowaway with a portable mount too.
