Terminator of an 8 day old Moon

Posted By John Krawczyk
Hi All

Here is another mosaic from the 18th that shows the whole length of the terminator. The south pole region was hard to keep from blowing out, but the rest of the image came out rather nicely. Same camera and setup as the Lunar Montes image. In fact the images share two common image tiles. This mosaic is (8) 640x480 images combined in iMerge and cropped. The link is to a full size image.

Markarians Chain w/Nikon D70

Posted By John Krawczyk
Hi All

Markarian Chain of galaxies in the Virgo Cluster of galaxies. In addtion to the obvious ones, i got some of the real faint fuzzy mag 14-16 IC galaxies. You can find them in the full size(2.5MB)image at the link below. The image is a combination of 12x4.5 min ISO1600 and 20x5min ISO1600 shots taken from my light polluted backyard near Annapolis, MD. The scope is a Stellarvue SV102 APO on a Losmandy G11. I used a .8x focal reducer and IDAS LPS filter.

M-64 The Blackeyed Galaxy

Posted By John Krawczyk
Hi All,

I put together this image from Luminace data i shot in early March with RGB data i shot on Saturday night to make this nice image of the Blackeyed galaxy. The seeing and tranparency were 4/5 on Sat., so i wasnt gonna waste it inspite of a bright moon!

Here is the shooting data:

Scope: Stellarvue SV-102 APO @ f/4.9 w/Celestron .63x focal reducer for the RGB frames and f/7.8 (native FR) for the Luminance frames
Camera: ATIK-2HS
Exposures: 76:49:32:42 240 sec subs for lum 50% gain amp off, 210 sec subs for RGB 70% gain amp off.
Mount: Losmandy G11
Guiding: ST-4 autoguider and SV80/9d guidescope
Filters: Astronomik LRGB Type 2 & IDAS LPS

To process i used Images Plus, Registar, Paintshop Pro 8 and PixInsight's DBE tool to remove the nasty moon gradients (what a great tool).

Thanks for looking!

Plato w/4" apo

Posted By John Krawczyk
Hi All

I had some good seeing last night and with a good sun angle coupled with my most excellent Stellarvue SV102, it let me push the envelope of the scopes performance at f/35ish using a 2x barlowed 2.5x powermate and an ATIK-2HS w/green dichroic filter. Imaging craterlets in Plato has been a goal of mine since i got this scope last October. I finally got the seeing i needed to do it. The image is about 100 frames stacked using Gassian wavelets tranform in Registax 3.

Thanks for looking

Valles Alpes w/4" apo

Posted By John Krawczyk
Hi All,

Here is another lunar image from 4/18. It was a great night to say the least. 2nd on my list of lunar feature, after Plato craterlets, to capture with 4" of aperture is the rille in Valles Alpes. While this is the best image i have of the Valley to date, i think it will require 5/5 seeing to image the rille itself. Again i was using my SV102 w/a 2x barlowed 2.5x powermate and a ATIK-2HS w/green filter to capture. Processing with Regstax 3.

M3 - Firstlight with HX916

Posted By John Krawczyk
Hi all. Here is my first image with my newly aquired HX916 and Homeyer filter wheel. The camera and wheel work great, but i've lots of software and computer issues to work out before i can truly automate my capture sequences. This image is very short on exposure since i was testing the setup and wasnt guiding on a very windy night. I tossed better than 50% of the images out on this reprocess of the image i posted on CN. This image ended up being LRGB 4:4:4:4 (min) with 45 sec. subs all calibrated with dark frames and Adaptive Added in Images Plus. Registration of the color channels and RGB combine were done with Registar. DDP strectch in IP and final processing with Paintshop Pro 8.

Re: If you could restore...

Porsche 356 Speedster.

I might break even on it, depending on how bad it was to start with. Restoring my low mileage 1979 Porsche 928 to concours would be a losing proposition, even though its a good 10' car. Its gonna make me a great street/track car and cost me less than a new Boxster. If only i would stop spending money on astrophotography gear....

My retirement dream is to live out in the mountains/country and restore old Porsches and build an observatory. I got about 23 years to go on the Porsche dream. The observatory dream make take another 10 to realize.

Heres a pic of my 928. I use it to haul my astro gear to starparties. Its the only vehicle i have right now that i can do this with. My pickup is too rough.

Re: When I win the lottery

Posted By John Krawczyk
Nice Choice! I like the 575 Marrenello too. As a 928 owner, the 575 would be right up my alley.

But if i won the lottery, i'd probably spend every last dime on this. Provided i could wrest one of the 39 GTO's ever built from a present owner

NGC6888 Ha w/4

Posted By John Krawczyk
Hi All,

Its been a while since i've posted anything here, as weather has been tough, or the images arent up to snuff. Warren was the early bird getting the worm here with his very nice image of the Cresent.

Here is the shooting data:

Scope: Stellarvue SV-102 APO @ f/7.8 (native focal ratio)
Camera: Starlight Xpress HX-916 1.3MP monochrome CCD
Exposures: 6x1200sec Ha bin 1x1
Mount: Losmandy G11
Guiding: ST-4 w/SV-80/9d Guidescope
Filters: Astronomik 14nm Ha

The image was calibrated with darks, bias and flat frames in Images
Plus 2.1. Then registered and sum combined in Registar 1.0. DDP and
log stretched in Images Plus.
