I would never tire of this area. Its actually my fav. So majestic. You havent forced the processing beyond what the seeing allowed. I found the seeing here quite jittery. 

Nice capture. look forward to seeing more.

Thanks Neil. Appreciate the comment. The seeing was certainly “iffy” and I agree, it’s a great area to image. 

Loads of files to wade through from last night. Seeing was very variable but it will keep me amused for a while ! This is a stitch of the first two AVI files using a 180 Mak and ASI 178. I've imaged this area many times before but always come back for another go

That is a very good shot of the moon. Very hazy here on the south coast.  Did U 

use single shots of the moon stitched together .

Thanks Steve. I used three video files processed and then stitched together. 

As usual, a cracking image Neil. You certainly put time and energy into getting things right 👍

That's a nice image. Lots of fine detail.

Very nice and natural appearance to it.

Thanks. I'm always tempted to overdue the processing, particularly sharpening I think.

Very nice image. I was out at the same time with my 130mm APO.  Yes, the moon was getting lower by then and seeing also not as good as earlier.

Thanks Bradley. The seeing does makes all the difference.

Some of the files seem better than I thought. I've over cooked some of the highlights but I was pleased with the detail.  I always struggle with high contrast areas.  ED120 with x2 barlow and ASI 120mm last night. 

Thanks. It is a nice area to catch at sunrise / sunset

I think I missed the best seeing last night and didn't set up until about 10 o'clock as the moon was getting lower. It was also cooling rapidly so thought I would plum for a refractor. I don't think the 180 mak would have cooled down.  Taken at prime focus on an ED120 with an ASI 120 mm. Three panes stitched together. 

That’s a cracking picture. Very detailed.

Very nicely captured.

Cheers Pete. Lots to see at present

Lovely shots 👍

Looks very detailed to me Neil. Interested to see what you can get with the 10”. Seeing Petes C9.25 image I’m tempted to buy one of these sheets !!!! . Always something else to try😬

Cracking image Pete. Lots of fine detail.

Cracking image, congrates 👍

Thanks for the comment. 👍Trevor

It’s a stage 1 mod. Hope that helps

Taken yesterday through a modded pst on an ED100. Camera was a 618 imaging source. One day I'll tackle a whole disc !!

That’s very good. I’m really impressed with the detail and smoothness of the video 👍👍

A slight tilt somewhere might help relieve the Newton's Rings.
Some cameras are more prone to NR than others.
Some filter systems are more prone to it in H-a.
Monochromatic light and the camera's protective sensor cover will do it sometimes.

Uneven lighting and patchy detail are due to the so-called etalon sweet spot with larger apertures.
I rotate [clock] and mark my Blocking Filter housing relative to the PST etalon.
Rotate your BF and aim for darkest, most even and detailed image.
Electrical tape, on one edge of the BF, is aligned with the bit of tape stuck on the etalon housing. I find it helps.

If your PST mod is still in its original form then you may not be able to play with rotation.
My 150mm PST Mod uses the popular AOK Swiss PST Etalon Housings. One front and one back.

Thanks very much for the info. I will move the various elements around as you suggest and see what happens

Just going through what i got on the 21st

Bresser 127l baader 495 longpass UVIR Cut ZWO 178MM EQ5 PRO

Great images there Neil. Lots of fine granulation. I often wonder like Pete if I should add colour or not. Interesting point. I think I prefer the mono. Trevor

Clear blue skies, but tricky conditions today, poor seeing then high haze and wind.

White lights with the Evostar 120mm, Lunt wedge,  Asi174mm and H/A with Lunt 50mm

 

 

Lovely images Pete. Can’t think of a better way to spend a work break ! I find the seeing really takes its toll on the HA shots as well.

Beautiful images in both wavelengths

 

ThanksPete. I always find it interesting to compare the views. Trevor

When i read "PST" then saw the images I was like Whaaaat? my PST wasn't that awesome! then I realized its a 100mm with PST mod 🤣

Amazing work!

Thanks for the comment. I should really take flats as well to even the field up a bit. One for the future !

Lots going on at present ! The images are through an ED100 with and without a PST mod. I used a ASI 120MM and imaging source 618. For some reason the ASI produces interference patterns a bit like Newtons rings when I use the mod with a ERF filter over the objective. Haven't a clue why but someone may explain ?
