Hello,This nebular region in Cepheus sits just over 11 degrees from Polaris, and largely consists of a diffuse dark nebula and bright nebula cataloged by Beverly T. Lynds in 1965 as LDN 1228 and LBN 552, respectively. Near the center of the image sits a unique orange reflection nebula, cataloged both as GN 21.00.4 and Cohen 129, which appears as a hill popping from the dimmer diffuse nebula region. This frame shows only part of the LBN 552 and LDN 1228 structures, which cover a much larger area and themselves are part of an even larger system of clouds in this area of the Milky Way.Thank you very much

Spring is coming and galaxies are coming along too.
After more than a year without imaging, I have the pleasure to present you the Lion Triplet with my new material.
The Leo Triplet, or the M66 Group, is a group of interacting spiral galaxies located in the northern constellation Leo.The group consists of the galaxies Messier 65, Messier 66 and NGC 3628, also known as the Hamburger Galaxy. The Leo Triplet lies at an approximate distance of 35 million light years from Earth.
The three large spiral galaxies can be seen in a single field of view and are well viewed even in small telescopes. Their galactic disks are tilted at different angles when seen from Earth. NGC 3628 appears edge-on, while M65 and M66 are inclined enough to reveal their spiral arms.The three galaxies in the M66 Group have all been affected by gravitational interactions with each other. This is evident in the deformed, drawn out spiral arms of M66 that are experiencing a high rate of star forming activity and in the warped, inflated disk of NGC 3628. With a prominent tidal tail consisting mainly of young blue stars, NGC 3628 seems to be the most affected of the three, while M65 appears to have suffered the least damage from the interaction. The tidal tail of NGC 3628 spans over 300,000 light years, but is very faint and does not always appear in images of the galaxy.

According to ASA, it seems that the steps size are 5 um.
On the other hand, with 5um, I feel that with software @ Focus3 Software Bisque, it works not too well ....
-
Hello,
I search the step size in micronmeter (x um/step) for AAF3 focuser. I have difficult ton find this information.
Thank you in advance for your repply
-
Hello,
I would like know the Resolution per step (in µm) of AAF3 focuser.
I would like used @Focus3 of TheSkyX and this parameters is not available.
Thank you in advanced.

Merci Bernard

Hello,
I currently have a problem connecting the AAF3 focuser.
After installation, I get this error message when opening the software and I can not use it:

Hello,
I noticed some weird egrets on a big star at the edge of the field.
I am shocked by the horizontal egret on the star.
While on all other stars it does not appear :
Thank you for your help

Hello,So, Please find my test image.I tried to adjust the collimation as best as possible with the option "real time" and then I took a break of 20s BIN1x1.Technical specifications include:- Newton 254/1000- Paramount MyT- ASA 0.73x corrector- Moravian G2-4000- Image scale: 2,032- Focal: 751.12- RA 15 04 05.392- DEC +26 48 25.53The goal for the moment is to find the correct distance of the backfocus for the corrector.The TILT will be the next step.For Downloading Image .fit :
This is the field :
With the four corners and the center of the image to see the appearance of the stars :
Zoom on the center of the image :
With CCDInspector :
It is true that there is a lot of Tilt but this will correct later.Here are the questions:1 °) So what do you think of these results regarding my bacfocus for the corrector?2) Is the accuracy of the collimation sufficient?3 °) In "settings"> Collimation screw direction> Clock-wise = pull is selected. I can not understand. In particular with the following image :
Thank you very much in advance for your help
-
Thank you
How do you check that? (the good distance for Backfocus)Do you use software like CCDInspector to see if the distance is good? (see coma) -
thank you mark !
Just to be sure :
Backfocus CCD moravian and filter wheel : 33,5mm
Connected rings : 15mm
AOG : 15 mm
Filter astrodon : - 1mm
So : (33,5 + 15 + 15 - 1) = 62,5 mm
In conclusion, add 3mm extension rings to obtain 65,5mm
-
Sorry, but my focal length is 1000mm (Newtonian 254/1000 FD4).
So i calculate 65,5mm is that correct ?
Thank you

Thank you very much for your help

Edit : more information about telescope
254mm diameter
Focal lenght : 766.94mm with ASA reducteur (astrometry)

Hello,
I own the ASA 2" reducer 0.73 and I can not find the right measure for the BackFocus.Here is my equipment:Newton telescope : focal 766.94mmI tried with the table in the documentation of the correction but I can not be the measure precisely.Thank you in advance for your help.Have a good day
