It appears that one of Jupiter's moons is starting to cross while I was capturing this image. Kool affect!!

2x Barlow, TV 1/30, 10fps, 240 seconds capture rate.



Hi John, thats a very decent image you captured, some nice detail in this shot, it seems to me though, that your clipping the black point a little to much in levels, this will sometimes help with the detail but your loosing some of the full globe of Jupiter in the process.

just my thoughts, others might disagree, but it is a very nice image just the same.

Tom.

I took a few video clips last night with 2x barlow and NexImage (about 1000 frames, processed in AviStack2). This pic is my favourite so far as I like the craters on the left side of the ridge. It needs a bit more processing but I'll share it now...

It can be start of a new game - "Name That Moon". You tell me the number of craters you need to identify this part of the moon! The most useful information I can give is that it appeared around the bottom left...

Also I like AviStack but it seems to crash a lot - anyone else get this? :question:


Hi Andy,

nice capture, some further processing will i`m sure enhance it very nicely, love the wrinkle ridges too, nice one.

You seem to have a reflection in the lower right of the image, any ideas whats causing it?

Tom.

Hi Tom,

You have a great eye for how images are processed via Registax. Yes, I did clip the black point a little to much in levels. I'll be more aware of this next time.

Thanks for your kind words & input!!

Moon: 2x Barlow used, TV 1/30, 10fps, 240 seconds capture rate, RegiStax, no photoshop

I sacrificed the side of this image to gain the max details of the carter via the wavelets.

Oops, I did use a 2x Barlow

Yes John,

the center of the image is pin sharp, great detail in the crater, well done!

Hi Tom

Not sure what the reflection is - moonlight?! I tried unsuccessfully to remove it from the image which is why I think it needs further processing. I was struggling with the Burn & Dodge tools on this image - and running out of time - for some reason the boss wanted me to finish my lunch and get back to work again.

Thanks for your comments. If I get chance I'll rework it and see what happens. :grin:

Last night I did a little experimenting with a DSI2 OSC attached directly to a 180mm Nikon Lens. I attched that assembly to a dovetail mount ( ring around the Lens), and mounted that onto the Nexstar 8 mount.

I was rather surprised to get 45 second images in Alt/Az Mode. This is a compliation of 25 images.I am located in a fairly light polluted area (mag 3.5). I'm not impressed so much by the image as the stability of the mount.

I entered 50% backlash adjustement to all of the settings- Alt/Pos&Neg and Az Pos&Neg. Before that, I couldn't manage 20seconds.

I also used Dan's instruction about Alignment and later with Enter and Alignment approach. That gets tricky when the sensor on the camera is upside down..I kept asking myself..."so, which way is right and up?" :roflmao:

Every nice Tom! I'm not familiar with this object, but there appears to be a Neb in the lower left.

What is this photo of?

By the way, I grew up 10 miles NW of Boston.

err...

John, this is the Horsehead Nebula (also known as Barnard 33 / B33) in Orion.

The bright star centre left is Zeta Orionis and the emission nebula underneath Zeta Orionis is NGC 2024. The star centre top is Sigma Orionis. The red background is the emission nebula IC 434 and also visible is the reflection nebula NGC 2023.

This is a NASA photo of the Horsehead Nebula:

Posted Image

RA 5:41, Dec -2:24 (Orion)
Distance: 1500 ly
Type: dark nebula / diffuse nebulae
Zeta Orionis (Alnitak) is the easternmost star in Orion's belt.

BTW - shouldn't this reply and your preceeding post be in the disussion thread :question:

Thanks! I now can see the horsehead in Tom's photo.

I think the "no reply" within this thread has died a slow death. But at least people are posting photos!!

BTW, John, That's the Flame Nebula -NGC 2024- that you were asking about in the lower left. The HHN itself is listed as IC434, just below the first star, Alnitak, in Orion's belt ( from left to right). Don't expect to see it naked eye unless you've got one big scope and a very dark sky. I saw the HHN once through a 15" Odyssey Dob and it was one of those moments in Observing that are unforgettable.

Hi Tom,

Please don't be daunted by comparisons of your image of the Horsehead and its surroundings with those produced by Hubble et al: there's a wealth of data in yours.

I hope therefore you don't mind but I took the liberty to uncover some of it with the following result:

Best regards,

Hi guys, did you use a H-beta filter or just take it as it came?

Hi..?

I didn't use an Halpha filter. I was just using a DSI 2 Meade color camera. What's surprising is that the DSI2 OSC is not as sensitive as the mono versions, and my skies are very glary. It's a wonder I got anythng at all from such a faint target. Tel reworked my image.

This is an image I took the other night in HA ( NOT with the Nexstar mount :lol:) Posted Image

The above image was with a DSI 3 mono camera through an Orion ED80 refractor on top of an LXD 75 Mount.

I took 5 8minute exposures using PHD guiding and then processed the image in Images Plus twith Darks and Flats.
