H-alpha view of Pelican Nebula -- wide and narrow

Posted By Thomas V Davis
I shot this last night -- fullish moon.

Here is the wide view:

AP155EDF f/7
STL11000M Ha 6nm 120 min.

M33 (smaller scope - less time)

Posted By Thomas V Davis
Hi All,

I also took some images of M33 recently. I wasn't sure if it would turn out OK but I thought I'd process the data anyway. I was inspired by Tyler Allred's recent posting -- it was absolutly wonderful.

My image has much less exposure time and was taken through a smaller aperture scope than Tyler's. I need to add more exposure time.

AP 155 EDF f/7
.67x reducer
ST-10XME
LRGB 33:15:15:15 minutes

It's a tough object to get the processing right.

M15

Posted By Thomas V Davis
Here's a test image from last night. I'm still trying to get the BRC collimated. Very challenging -- at least for this small brain.

BRC-250 f/5
STL-11000M
RGB 25:25:25 min

I still don't have my PDF so the focus is not right on -- the FWHM was 2.8 by my hand focusing.

Helix revisited

Posted By Thomas V Davis
I added to my Helix data from last year and tried to process to bring out more of the outer ring.

Cheers,

IC 405 Flaming Star Nebula in H-alpha

Posted By Thomas V Davis
I took this over the last few nights. I'll try to get the color data in a few weeks.

IC410/NGC1893 revisited

Posted By Thomas V Davis
I obtained more data and added it to an image I started last year. This is IC410 in Auriga (the nebula) and NGC1893 (the open cluster in the nebula). The two interesting objects just left of center are called the "tadpoles".

Best,

Tom

NGC7380 and little bubble

Posted By Thomas V Davis
Since the weather has not been cooperating I've been revisiting some data from this time last year. I've changed cameras since then but I learned some different processing techniques so I thought I'd try them out on old data. My recent post of IC410 was one of these experiments.

Well, this is NGC7380 in Cepheus. It has many interesting "wave-like" dark nebulae which make it look like part of a restless ocean. One of the interesting objects within NGC7380 is another bubble nebula. It is much less well known but it would be a great target for those of you (Dan Kowall) with big RC's or other larger aperture/longer f.l. instruments. My humble AP 155EDF can pick it up but not with much detail.

The first post is of NGC7380. The image on the next post is cropped to show the bubble.

ST-8XE (HaR)RGB (120,60):60:60:60 minutes.

Best,

Horsehead and Flame in Ha

Posted By Thomas V Davis
Here is my first attempt at these objects this year. I haven't shot these for about three years so I thought it was time again.

AP155EDF f/7
STL-11000M
Ha 6nm 160 minutes

I'm still waiting for my BRC to get back from TNR in Houston. Hopefully it wasn't damaged during the deluge.

Perseus Double Cluster

Posted By Thomas V Davis
I shot this last night while waiting for another target to rise. They look like celestial gems.

IC 405 Flaming Star HaRGB

Posted By Thomas V Davis
Here's the color version of my recent post of IC 405 in Auriga. I'm not completely satisfied with the results but it's a good start. I had some moon gradients to deal with that made the processing more difficult.

AP 155EDF f/7
STL-11000M
(HaR)RGB (160,60):60:60:70 minutes. Color RGB bin2
